The premise iswrong…”Earlier theories of motivation IIHumanistic psychology (Maslow): satisfaction of basic needs:PhysiologicalSafetyLoveEsteemself-actualizationCurrent dominant paradigmsCognitive revolution:Chomsky’s review of Skinner’s Verbal Behavior contributed to a declineof behaviorist theories and the development of cognitive theories Cognitive and social theories:People viewed as autonomous, thinking beings with minds, who are opento influences from their environment and social context, but are not fullydetermined by those influences.Language Learning MotivationThe most influential approach to motivation in language learning: R.C.

and (b) the individual is convinced that the goal is attainable.Goal Theories IIIGoal orientation theoryMastery orientationFocus on learning, mastering content: “task-involvement goals”Performance orientationDemonstrate ability, get good grades, do better than others: “ego-involvement goals”Self-determination theory IDistinction between intrinsic and extrinsic regulation of motivationIntrinsic:To experience pleasure, satisfy curiosityExtrinsic:Means to an end, receive awards, avoid punishmentAmotivation:Lack of regulation: “there is no point”; “I don’t know why I’m doing this”feelingSelf-determination theory IIContinuum of different types of extrinsic regulation (Vallerand, Deci & Ryan, Noels et al.)External regulation (or extrinsic): least self-determined: doing somethingdue to external pressuresIntrojected regulation: doing something because you think you should: obeya rule, conform to an external expectationIdentified regulation: doing something because you recognize its personal importance (e.g. hobby)Integrated regulation: doing something because it is considered part ofone’s self-identityMotivation as an individual difference variable in SLASome individual difference variables that have been studied:AgeAptitudeCognitive styleStrategy useAttitudes and MotivationThe role of age in SLAThe Critical Period HypothesisIs there an age after which native-like proficiency in an L2 in no longerattainable?Sometimes called “sensitive period”Research findings mixed: “yes and no”Before age 7, native-like proficiency quite certain7 to 14: more variation in degree of accentednessAfter age 14, native-like proficiency sometimes considered impossible, but some succeedNo biological evidence for critical periodAccess to Universal Grammar (UG) in SLAResearch related to role of age focuses now on learning mechanisms involved:Do L2 learners have access to Universal Grammar (specialized cognitive structures for language)?Issue still the subject of hot debateSome research supports hypothesis of UG accessOther research points to use of general learning mechanisms: e.g. gender in FrenchAptitudeDifferences in natural ability to learn an L2Partly related to general intelligence, partly distinctHas been shown to play an important role in language learning achievement Aptitude is focused on less nowadays in L2 education: preference to think in terms of what can be changedComponents of language learning aptitudePhonemic coding abilityAbility to identify sounds, establish sound-symbol linksGrammatical sensitivityAwareness of grammatical patterns, structuresInductive language learning abilityAbility to infer form-meaning links from contextRote learning abilityAbility to form and remember associations;

In the pursuit of academic excellence, it is crucial to develop and refine strategies that foster effective learning. The process of enhancing one's learning experience transcends mere rote memorization and involves a multi-dimensional approach that encompasses cognitive, emotional, and environmental aspects. This essay delves into various key elements that contribute to optimizing learning, offering a comprehensive and high-quality roadmap for students seeking to elevate their academic performance.1. **Establishing a Strong Foundation of Motivation**A compelling drive to learn is the cornerstone of academic success. To cultivate this motivation, it is essential to identify personal goals and aspirations, linking them explicitly to the learning process. This can be achieved by setting specific, measurable, achievable, relevant, and time-bound (SMART) objectives, which provide clear direction and a sense of purpose. Moreover, understanding the intrinsic value of knowledge acquisition, such as its potential to broaden perspectives, foster critical thinking, and enhance career prospects, can further fuel motivation.Additionally, extrinsic motivators, such as praise, rewards, or the prospect of higher grades, can also play a role in maintaining momentum. However, it is crucial to strike a balance between intrinsic and extrinsic motivation, as overreliance on external factors may undermine long-term interest and engagement.2. **Adopting Effective Study Techniques**The methods we employ to process and retain information significantly impact our learning outcomes. Here are some evidence-based study techniques: **Active Learning:** Engaging in activities like summarizing, discussing, teaching, or applying concepts promotes deeper understanding and retention compared to passive reading or listening. Techniques like the Feynman Technique, where one explains a concept to an imaginary audience in simple terms, can be particularly effective.**Spaced Repetition:** Revisiting material at increasingly longer intervals helps consolidate memories in long-term storage. Tools like flashcards or digital apps like Anki can facilitate this process.**Interleaving:** Alternating between different subjects or types of problems during a study session enhances retention and problem-solving skills by forcing the brain to discriminate and adapt to varying contexts.**Deep Processing:** Encouraging elaboration, organization, and critical thinking about the material, rather than superficial processing, leads to better retention and transfer of knowledge. Techniques like mind mapping or the PQ4R (Preview, Question, Read, Reflect, Recite, Review) method can promote deep processing.3. **Cultivating a Growth Mindset**A growth mindset, as opposed to a fixed mindset, embraces challenges, views effort as a path to mastery, and learns from setbacks. Cultivating this mindset involves:**Embracing Challenges:** Seeing difficult tasks as opportunities for growth rather than threats to competence.**Valuing Effort:** Recognizing that intelligence and talent are malleable and can be developed through persistent effort.**Learning from Failure:** Perceiving failures as informative feedback rather than a reflection of inherent abilities, and using them to adjust strategies and persist in learning.4. **Managing Time Effectively**Efficient time management is vital for balancing academic responsibilities, personal life, and self-care. Strategies include:**Creating a Study Schedule:** Designing a structured yet flexible plan that allocates time for coursework, revision, breaks, and leisure activities.**Prioritizing Tasks:** Using tools like the Eisenhower Matrix to categorize tasks based on urgency and importance, ensuring focus on high-value activities.**Minimizing Distractions:** Identifying and eliminating or mitigating distractions, such as social media or multitasking, to enhance concentration during study sessions.**Practicing Self-Discipline:** Establishing routines, setting boundaries, and holding oneself accountable to maintain consistency and productivity.5. **Promoting Physical and Mental Well-being**Optimal learning is contingent upon good physical and mental health. Steps to nurture well-being include:**Maintaining a Balanced Diet:** Consuming a diet rich in nutrients, vitamins, and minerals to support brain function and energy levels.**Regular Exercise:** Engaging in physical activity to improve mood, reduce stress, and enhance cognitive function.**Quality Sleep:** Ensuring adequate sleep to facilitate memory consolidation, attention, and emotional regulation.**Mental Health Support:** Seeking help when needed, practicing stress-reduction techniques like mindfulness or meditation, and cultivating positive relationships for emotional support.6. **Leveraging Technology and Resources**In today's digital age, technology offers numerous tools and resources to augment learning:**Online Learning Platforms:** Utilizing platforms like Coursera, Khan Academy, or edX for supplementary learning materials, interactive exercises, and expert insights.**Educational Apps:** Exploiting apps like Duolingo, Quizlet, or Evernote to facilitate language learning, memorization, or organization.**Collaborative Tools:** Employing tools like Google Docs, Zoom, or Slack to facilitate group work, discussions, and peer learning.7. **Engaging in Continuous Feedback and Reflection**Continuous assessment and reflection are instrumental in identifying strengths, weaknesses, and areas for improvement. Strategies include: **Self-Assessment:** Regularly evaluating one's understanding, progress, and study habits using quizzes, self-tests, or reflection journals.**Peer Feedback:** Seeking constructive criticism and suggestions from classmates, study groups, or online forums.**Teacher Feedback:** Actively engaging with instructors, asking questions, attending office hours, and incorporating their feedback into learning strategies.**Formal Assessments:** Analyzing exam results, assignment feedback, and course evaluations to inform future learning approaches.In conclusion, enhancing learning is a holistic endeavor that requires a blend of motivation, effective study techniques, mindset cultivation, time management, well-being promotion, technology utilization, and continuous feedback. By integrating these multifaceted strategies, students can embark on a transformative journey towards academic excellence, fostering not only improved grades but also a lifelong love for learning and a robust set of skills applicable beyond the classroom.。

自我管理作文英语Self-management is a critical skill that plays a significant role in our personal and professional lives. It encompasses the ability to regulate our emotions, thoughts, and behaviors in different situations, as well as effectively manage our time and resources. In this essay, we will delve into the historical background and development of self-management, analyze various perspectives and opinions surrounding the topic, provide case studies and examples to illustratekey points, offer a critical evaluation of the benefits and drawbacks of self-management, and conclude with future implications and recommendations related to the title.Historical Background and DevelopmentThe concept of self-management has roots in ancient philosophy, with thinkers such as Aristotle and Confucius emphasizing the importance of self-control andself-discipline. However, the modern understanding of self-management has evolved significantly, particularly in the context of organizational behavior and psychology. In the 20th century, influential psychologists like Abraham Maslow and Carl Rogers contributed to the development of self-management theories,highlighting the significance of self-awareness, self-regulation, and motivationin achieving personal growth and success. Today, self-management is a key focus in fields such as leadership development, emotional intelligence, and stress management, reflecting its enduring relevance in contemporary society.Different Perspectives and OpinionsThe topic of self-management elicits a wide range of perspectives and opinions. Some individuals view self-management as a fundamental skill for personal and professional success, emphasizing its role in fostering resilience, adaptability, and productivity. They argue that individuals who possess strong self-management abilities are better equipped to navigate challenges, make informed decisions, and achieve their goals. On the other hand, critics may argue that excessive emphasis on self-management can lead to burnout and unrealistic expectations, particularlyin high-pressure work environments. They suggest that a more balanced approach,which incorporates support systems and collective responsibility, is essential for sustainable well-being and performance.Case Studies and ExamplesTo illustrate the importance of self-management, we can consider the case of Steve Jobs, the co-founder of Apple Inc. Known for his visionary leadership and innovative mindset, Jobs exemplified the power of self-management in driving personal and professional success. Despite facing numerous setbacks and challenges, he maintained a steadfast commitment to his goals, demonstrating resilience, focus, and self-discipline. Similarly, in the context of academic achievement, research has shown that students who possess strong self-management skills, such aseffective time management and goal setting, are more likely to excel in their studies and extracurricular activities. These examples underscore the tangible impact of self-management on individual outcomes and success.Critical Evaluation of Benefits and DrawbacksWhile self-management offers various benefits, it is essential to critically evaluate its drawbacks and limitations. One potential drawback is the risk of excessive self-reliance, which may hinder individuals from seeking support or collaboration when needed. Moreover, the pressure to constantly self-manage can contribute to stress and anxiety, particularly in competitive and fast-paced environments. Additionally, individuals with limited access to resources or facing systemic barriers may encounter challenges in developing and applying self-management skills, highlighting the importance of addressing broader societal factors in fostering personal development.Future Implications and RecommendationsLooking ahead, the future implications of self-management are multifaceted. As technology continues to reshape the nature of work and communication, individuals will need to adapt and refine their self-management skills to thrive in evolving environments. Furthermore, there is a growing recognition of the interconnectedness between individual well-being and organizational success, underscoring the need for holistic approaches to self-management that prioritizemental health and work-life balance. To that end, recommendations for promoting effective self-management include integrating well-being initiatives in educational and workplace settings, fostering a culture of open communication and support, and providing accessible resources for skill development and self-care.In conclusion, self-management is a complex and multifaceted topic that holds significant implications for personal and professional development. By examining its historical background, analyzing different perspectives, and critically evaluating its benefits and drawbacks, we gain a deeper understanding of its relevance in contemporary society. As we navigate the complexities of the modern world, the cultivation of effective self-management skills emerges as a valuable asset for individuals and organizations alike. Embracing a balanced and inclusive approach to self-management, grounded in empathy and self-awareness, can pave the way for sustainable well-being and success in the future.。

原文:Merger Policy and Tax CompetitionIn many situations governments have sector-specific tax and regulation policies at their disposal to influence the market outcome after a national or an international merger has taken place. We find that whether national or international mergers are more likely to be enacted in the presence of nationally optimal tax policies depends crucially on the ownership structure of firms. When all firms are owned domestically in the premerger situation, non-cooperative tax policies are more efficient in the national merger case and smaller synergy effects are needed for this type of merger to be proposed and cleared. These results are reversed when there is a high degree of foreign firm ownership prior to the merger.Mergers have played a prominent role over the past decade, and international merger activity has grown particularly fast. During the period 1981-1998 the annual number of mergers and acquisitions (M&A) has increased more than fivefold and the share of cross-border mergers has reached more than one quarter of the total by the end of this period. This increase in merger activity has led to situations where a national or an international merger have been in direct competition with each other. A recent example has been the bidding race for the leading Spanish electricity provider Endesa, where the German-based E.ON company initially competed with the Spanish-based rival Gas Natural. The Spanish authorities favored the national merger and formulated severe obstacles to an international take-over by E.ON, which was one of the reasons why E.ON eventually withdrew its bid.A different approach has been taken by the British government, which has fully liberalized its electricity market in the early 1990s. In this process, foreign electricity providers (among them E.ON ) took over a large part of the British electricity industry. The British government responded to high profits in this and other privatized industries by imposing a one-time, sector-specifi c ‘windfall pro fi t tax’ in 1997. Since then, a renewed imposition of this tax has been repeatedly discussed as a complement to the regulation of prices through the regulation authority Ofgem (Office of Gas and Electricity Markets).The last example shows clearly that national governments dispose overadditional policy instruments in an industry where a merger or a foreign acquisition has taken place. Price regulation in privatized `network industries' is one important way to increase domestic consumer surplus at the expense of corporate profits, which often accrue, at least in part, to foreign shareholders. Sector-specific profit taxes have very similar effects, if their proceeds are redistributed to consumers in compensation for higher goods prices. On the other hand, there are also many industries where subsidies are granted in order to improve the competitiveness of domestic products in world markets. One set of examples are direct subsidies to specific sectors, such as mining, shipbuilding, steel production, or airplane construction. Moreover, several of these sectors and several others (e.g. air transportation) also receive indirect subsidies by paying reduced rates of excise taxes, in particular mineral oil or electricity taxes. To the extent that these `eco taxes' represent Pigouvian taxes that cause firms to internalize the true social cost of their products, such tax rebates also represent subsidies to the involved sectors and, importantly, to the electricity and energy sector itself. In all these cases, sector-specific tax or subsidy policies can be adjusted by national policymakers in response to a change in market structure caused by a merger.we argue that the possibility to levy industry-specific taxes or subsidies in a nationally optimal way has important repercussions on the position that national regulation authorities take vis-µa-vis a national or an international merger proposal. At the same time, merging firms will incorporate a possible change in policy when deciding about a merger in a particular country. To analyze this interaction between tax and merger policies we set up a model where both firms and merger regulation authorities anticipate that taxes will be optimally adjusted in the host country after a merger has taken place. More specifically, we investigate a setting of Cournot quantity competition between four producing firms where two firms are located in each of two symmetric countries. Importantly, these firms may have foreign shareholders, thus giving an incentive to each government to employ profit taxes that can be partly exported to foreigners.Starting from a market structure of double duopoly, our focus is on the comparison between a national merger in one of the countries and an international merger between a home and a foreign firm.Our analysis shows that the relative attractiveness of a national versus an international merger depends critically on the degree of foreign firm ownership. When all firms are nationally owned prior to the merger, then a national merger will lead to more efficient tax policies as compared to the international merger. In contrast, when the level of foreign firm ownership is high initially, then non-cooperative tax policies in the host countries will be more efficient under the international merger. Extending the model to allow for synergy effects of mergers, we show that these welfare properties translate into the national (international) merger being more likely to be proposed and adopted when the degree of foreign firm ownership is low (high). These results imply that a more geographically dispersed ownership structure of firms, in combination with non-cooperatively chosen national tax policies, may offer one explanation for the recent surge in cross-border merger activity.Our analysis relates to two strands in the literature. First, there is a growing recent literature on merger policies in open economies. This literature, however, typically regards merger control as an isolated policy problem for national or international regulators. The literature that analyses the interaction of merger control with other policy instruments is scarce, and it almost exclusively focuses on international trade policies as the additional policy variable (Richardson, 1999; Horn and Levinsohn, 2001; Huck and Konrad, 2004; Saggi and Yildiz, 2006). In contrast, the interaction between merger policy and national tax policies has not been addressed in this literature so far. A second literature strand on which our paper builds is the analysis of optimal commodity taxation in oligopolistic markets (Keen and Lahiri, 1998; Lockwood, 2001; Keen et al., 2002;Haufler et al.,2005;Hashimzade et al.,2005). This literature, however, has focused mainly on issues of commodity tax harmonization and the choice of commodity tax regime under an exogenously given market structure. It has not addressed the implications for tax policy that follow from changes in the underlying market conditions as a result of mergers.The plan of the paper is as follows. Section 2 describes the basic framework for our analysis. Section 3 presents the benchmark case of double duopoly, where two firms are located in each country and all four firms compete in both markets. Section4 analyzes the changes in tax policies and welfare when a national merger occurs in one of the countries. Section5 carries out the same analysis for an international merger. Section6 introduces synergy effects associated with a national and an international merger and compares the conditions under which one or the other type of merger is proposed and accepted by merger authorities. Section7 concludes.In practice a core motivation for firms to undertake mergers, and an important reason for regulation authorities to permit them, is that mergers can create synergy effects. We analyze how large the cost savings must be for a national or an international merger in order to be in the interest of both the merging firms and the regulation authority of the host country. We deal again with different ownership structures of firms. Due to the complexity of the resulting expressions, we confine the discussion in the main text to the polar cases of full national ownership and complete international ownership diversificationWe should observe a positive and systematic relationship between the foreign ownership share and the share of cross-border mergers in a particular industry. There is indeed some first, suggestive evidence in favour of this proposition. In the OECD countries the share of cross-border mergers in the total number of M&A cases differs widely across different economic sectors and is highest in manufacturing. At the same time, manufacturing is also one of the most internationalized sectors with respect to foreign ownership, at least in European countries. Similarly, there are sectors with a low share of foreign firm ownership, such as construction, where the share of cross-border mergers in the total number of M&A cases is also low. A detailed empirical study would be needed to rigorously test whether this positive relationship between foreign ownership and the share of cross-border mergers holds more generally, and whether it can be linked to the interaction of nationally optimal tax policies and merger control.In many industries governments have sector-specific tax and regulation policies at their disposal to influence the market outcome after a change in market structure has occurred. In this paper we have set up a simple model to analyze how nationally optimal tax rates will be adjusted in response to a national merger on the one hand andan international merger on the other. Extending the analysis to incorporate synergy effects of mergers, we have then studied how these changes in tax policy feed back on the incentives for firms to propose one or the other kind of merger, and for the merger regulation authorities to accept it.Our analysis shows that a national and an international merger lead to different incentives for national tax policy. On the one hand an international merger increases the 24 incentives for non-cooperative tax policy to tax foreign firm owners in excess of the efficient levels. On the other hand, an international merger leads to a larger share of consumption in each country being served by local producers and thus increases the incentive for each country to grant Pareto efficient subsidies. Which of these two effects dominates depends crucially on the share of foreign firm ownership in the pre-merger situation. If all firms are locally owned initially, then the national merger is the dominant alternative, in the sense that it requires fewer cost savings in order to be proposed by the merging firms and to be cleared by the regulation authority. In contrast, if the share of foreign firm ownership is large, then the international merger will be proposed and cleared for a wider range of cost savings.One implication of our model is that a rise in international portfolio diversification will favour cross-border mergers, other things being equal. When, as it is often argued, a rise in foreign asset holdings is one of the consequences of economic integration, then our analysis provides an explanation for the rising share of cross-border mergers. In principle our argument is complementary to other reasons for cross-border mergers found in the literature, in particular the argument that they allow firms to save aggregate transport costs. It is interesting to note, however, that this alternative argument cannot explain a rising share of cross-border mergers over time, as it becomes less important when economic integration proceeds and transport costs accordingly fall.Our analysis could be extended in several directions. One possibility would be to indigenize the share of foreign firm ownership, and relate this share explicitly to the forces of economic integration. In such a setting international portfolio diversification would lead to gains in the form of higher returns or lower aggregate risk, but it wouldalso cause higher information or transaction costs. If economic integration reduces the latter, the link between globalization and the rise of cross-border mergers could be explicitly modeled. We do not expect, however, that our conclusions would be fun- dementally altered by this extension. Another model extension would be to consider consecutive mergers, or `merger waves'. In such a setting it would be possible to derive equilibrium market structures for any given set of exogenous model parameters (as in Horn and Parson, 2001). In principle this extension could be incorporated into our model, but the analysis must account for both the change in market structure and for the change in tax policies following each merger. We leave this task for future research.Source: Andreas Haufle, 2007.”Merger Policy and Tax Competition”, Munich Discussion Paper No.39 P25-35.译文:合并政策和税收竞争通常政府有特定部门的税收和管理政策来处理国内并购或者跨国并购中产生的市场问题。
510(k) SUBSTANTIAL EQUIVALENCE DETERMINATIONDECISION SUMMARYINSTRUMENT ONLY TEMPLATEA. 510(k) Number:k170983B.Purpose for Submission:Modification of a previously cleared device to add a 6 second exhalation modeC.Manufacturer and Instrument Name:Circassia AB NIOX VEROD.Type of Test or Tests Performed:QuantitativeE. System Descriptions:1. Device Description:NIOX VERO is a portable system for the non‐invasive, quantitative measurement of the fraction of exhaled nitric oxide (NO) in expired human breath (FeNO).The NIOX VERO system is comprised of the NIOX VERO unit with AC adapter, arechargeable battery, an electrochemical NO sensor, disposable patient filters, and anexchangeable handle containing an internal NO scrubber filter. The NIOX Panel is anoptional PC application for operation of the NIOX VERO from a PC and access toelectronic medical record systems. The device can connect to the PC via a standard USB cable or wirelessly via Bluetooth.For testing, the patient empties their lungs, inhales deeply through the patient filter tototal lung capacity and then slowly exhales for 6 or 10 seconds, depending on the mode of operation. The default mode of operation is the 10 second exhalation mode. Inapproximately one minute, the NO concentration is displayed in parts per billion (ppb).Results are processed using dedicated software. The device has built‐in system controlprocedures and a Quality Control procedure to be performed on a daily basis.2. Principles of Operation:The measurement principle is based on American Thoracic Society guidelines (ATS/ERS Recommendations for Standardized Procedures for the Online and Offline Measurement of Exhaled Lower Respiratory Nitric Oxide and Nasal Nitric Oxide, 2005. Am J RespirCrit Care Med. 2005;171:912-930). The last three second fraction of a 6 second or 10 second exhalation is evaluated for average NO concentration. The exhalation flow is controlled to 50 ml/s ±5 ml/s at an applied pressure of 10 to 20 cm H2O. Sample isevaluated in 25 seconds (2 ml/sec for 25 seconds). The inhaled air is NO free. NO is measured using electrochemical detection. There is a gas inlet chamber with anelectrolyte (sulfuric acid solution) and hardware. The NO molecules diffuse through the membrane and reach the electrolyte. A chemical reaction takes place where one electron for each NO molecule is generated. The current is proportional to the number ofconverted NO molecules.3.

Regulation section:21 CFR 862.3080, Breath nitric oxide test system2. Classification:Class II3 Product code:MXA4. Panel:Clinical Chemistry (75)G. Intended Use:1. Indication(s) for Use:NIOX VERO measures Nitric Oxide (NO) in human breath. Nitric Oxide is frequentlyincreased in some airway inflammatory processes such as asthma. The fractional NOconcentration in expired breath (FeNO), can be measured by NIOX VERO according to guidelines for NO measurement established by the American Thoracic Society.Measurement of FeNO by NIOX VERO is a quantitative, non-invasive, simple and safe method to measure the decrease in FeNO concentration in asthma patients that oftenoccurs after treatment with anti-inflammatory pharmacological therapy, as an indication of the therapeutic effect in patients with elevated FeNO levels. NIOX VERO is suitable for children, 7- 17 years, and adults 18 years and older.NIOX VERO 10 second test mode is for age 7 and up.NIOX VERO 6 second test mode is for ages 7-10 only who cannot successfully completea 10 second test.FeNO measurements provide the physician with means of evaluating an asthma patient'sresponse to anti-inflammatory therapy, as an adjunct to the established clinical andlaboratory assessments in asthma. The NIOX VERO is intended for prescription use and should only be used as directed in the NIOX VERO User Manual by trained healthcareprofessionals. NIOX VERO cannot be used with infants or by children under the age of 7 as measurement requires patient cooperation.NIOX VERO should not be used in critical care, emergency care or in anesthesiology.2. Special Conditions for Use Statement(s):NIOX VERO should only be operated by trained healthcare professionals and only after careful reading of the NIOX VERO User Manual.The device should not be used with infants or by children under the age of 7, or anypatient who cannot cooperate with any necessary requirements of test performance.The device should not be used in critical care, emergency care or in anaesthesiology.Subjects should not smoke in the hour before measurements, and short- and long-termactive and passive smoking history should be recorded. In addition, subjects shouldrefrain from eating and drinking for 1 hour before exhaled NO measurement. Alcoholingestion reduces FENO in patients with asthma and healthy subjects FENO.It is prudent, where possible, to perform serial NO measurements in the same period ofthe day and to always record the time.For prescription use only.H.

Performance Characteristics:1. Analytical Performance:a. Accuracy:A method comparison study was performed to assess the agreement between the 6second and 10 second exhalation modes of the NIOX VERO in patients ages 7 – 10.The difference in FeNO measurements between the 6 second and 10 secondexhalation modes was not clinically significant.b. Precision/Reproducibility:Analytical precision for the 6 second exhalation mode was evaluated based on theCLSI standard EP5-A2. A certified NO calibration gas concentration of 200 ppb wasmixed with nitrogen gas in a gas mixer to create concentrations of 5, 25, 75, and 200ppb. Data was collected over 20 operating days, two runs per day, with duplicatedeterminations for each concentration. The repeatability and within-device precisionover 20 days were determined for each concentration. Five NIOX VERO sensors,continually mounted in 5 NIOX VERO instruments, respectively, were used. Theresults at the 5 and 25 ppb levels, expressed as standard deviation (ppb), and at the 75and 200 ppb levels, expressed as percent CV (%), are as follows:c. Linearity:Linearity of measurements using the 6 second exhalation mode was determined using certified NO at 200 ppb and 2000 ppb in nitrogen calibration gas mixed with nitrogen gas in a gas mixer, connected in-line with the NIOX VERO instrument, (withmounted NIOX VERO sensors), to obtain 7 NO concentration levels (3, 5, 25, 100,200, 300 and 330 ppb). Five replicate determinations of the concentrations at 3 and 5 ppb, and three replicate determinations on the other intervals were made.For the 10 devices tested, the regression analysis gave slopes of 1.05 to 1.09 andintercept ± 4 ppb. The squared correlation coefficient r2 was 0.999 for all 10 devices tested. Results indicate linearity within the 5-300 ppb measuring range.Effects of Temperature and Relative HumidityThe effects of temperature and relative humidity were characterized in k133898.Please refer to the Decision Memorandum for k133898 for details.d. Carryover:Not applicablee. Interfering Substances:The effect of potentially interfering substances was characterized in k133898.2. Other Supportive Instrument Performance Data Not Covered Above:Other clinical supportive data:A clinical study was not conducted with the 6 second mode of the NIOX VERO device.In 2007, a multi-center device randomized open-label prospective single-cohort study was conducted to demonstrate substantial equivalence between NIOX MINO andpredicate device (NIOX) when measuring the change of FeNO that often occurs after 2 weeks of corticosteroid therapy compared to their baseline levels. Symptomatic asthmatic males and females performed two valid FeNO measurements at each visit, with NIOX MINO and NIOX respectively, with a limit of six exhalation attempts per subject in each device. The order of the FENO measurement on NIOX MINO versus NIOX wasrandomized. At every visit and for every patient, spirometry was performed and asthma symptoms were recorded using Asthma Control Questionnaire (ACQ). In total, 156subjects were included, 105 adults 18 - 70 years old and 51 children 7 - 17 years old.Results from this study, in conjunction with the new method comparison study described above, were determined to be applicable to the 6 second mode of the candidate device, the NIOX VERO. See k072816 for more details.Traceability, Stability, Expected values (controls, calibrators, or methods):The NIOX VERO instrument is calibrated by the manufacturer and does not requirecalibration by the user. A replaceable sensor is used which is pre-programmed and pre-calibrated for a defined number of tests. The life time of NIOX VERO instrument is setto 5.5 years. The number of possible tests is 15000. The sensor life time is limited to 12 months in unopened packaging following manufacture, for 6 months from initialinstallation into NIOX VERO, or for the defined number of tests (60, 100, 300, 500 or1000), whichever comes first. The shelf life for NIOX Filter in unopened primarypackage is 2 years. NIOX Filter is for single use and must be replaced for every newpatient and measurement occasion. Stability information to support all claims wasreviewed in k133898.Detection limit:The detection limit of the NIOX VERO using the 6 second mode was determined in alaboratory setting, using mixtures of standard reference NO gas and nitrogen gas belowand above the detection limit, at 3 and 5 ppb. Five replicate determinations of eachconcentration were made. 10 NIOX VERO sensors, continually mounted in 10 NIOXVERO instruments, respectively, were used in these tests. The results of the study support the claimed detection limit of 5 ppb for the 6 second mode.Expected values/Reference range:The expected values are provided from the literature. In the labeling the sponsor states,“Given that physiological and environmental factors can affect FeNO, FeNO levels inclinical practice need to be established on an individual basis. However, most healthyindividuals will have NO levels in the range 5-35 ppb (children slightly lower, 5-25 ppb) when measured at 50 ml/s.(ATS/ERS Recommendations for Standardized Procedures for the Online and OfflineMeasurement of Exhaled Lower Respiratory Nitric Oxide and Nasal Nitric Oxide, 2005.Am J Respir Crit Care Med. 2005;171:912-930.)”K.

Regulation of Motivation: Evaluating an Underemphasized Aspect of Self-Regulated LearningChristopher A. WoltersDepartment of Educational PsychologyUniversity of HoustonSelf-regulated learning is often described as a function of students’motivation,cognitive strat-egy use,and metacognition.The purpose of this article is to emphasize regulation of motivationas another important aspect of self-regulated learning.To achieve this goal,a specific concep-tual understanding of regulation of motivation is proposed and used to clarify theoretical dis-tinctions between this process and motivation,metacognition,and volition.In addition,the di-verse nature of this regulatory activity is established by reviewing evidence showing students’use of several specific strategies for the regulation of motivation.The importance of this processis highlighted by discussing links between these regulatory strategies and indicators of students’motivation,cognitive engagement,and achievement.Finally,a guide for additional research re-lated to the theoretical definition,measurement,development and instruction of strategies forregulating motivation is identified.Models of self-regulated learning emphasize that students are more effective when they take a purposeful role in their own learning(Pintrich,2000;Schunk,2001;Zimmerman, 2000).Research in this area has emphasized that self-regu-lated learners are autonomous,reflective,and efficient learners who have the cognitive and metacognitive abilities as well as the motivational beliefs and attitudes needed to understand,monitor,and direct their own learning(see Boekaerts,Pintrich,&Zeidner,2000;Schunk& Zimmerman,1994).The focus of this article is on the regu-lation of motivation,an essential but less investigated as-pect of self-regulated learning.SELF-REGULATED LEARNINGThe specific characteristics most often attributed to self-regulated learners concern their motivational beliefs or attitudes,their cognitive strategy use,and their metacognitive abilities.Regarding motivation,self-regu-lated learners are thought to hold a collection of adaptive beliefs and attitudes that drive their willingness to engage in and persist at academic tasks.Specifically,these students tend to be highly self-efficacious individuals who are fo-cused on increasing their level of mastery and who view the material they are learning in school as valuable,interesting, and useful to know(Pintrich,2000;Schunk&Ertmer, 2000;Wigfield,1994).At the same time,self-regulated learners are viewed as having a large arsenal of cognitive strategies that they can readily and skillfully deploy to accomplish different aca-demic tasks.For instance,these students are proficient with a variety of rehearsal,organizational,and elaboration strate-gies(Alexander,Graham,&Harris,1998;Weinstein& Mayer,1986).Self-regulated learners also are perceived as metacognitively skilled regarding their awareness and use of cognitive strategies(Butler&Winne,1995;Zimmerman, 1989,1994).These students have a large store of metacognitive knowledge about learning strategies specifi-cally,and about the learning process more generally (Borkowski,Carr,Rellinger,&Pressley,1990;Pintrich, Wolters,&Baxter,2000;Zimmerman,1986).They are ca-pable of monitoring their learning and generating internal feedback about their cognitive processing(Butler&Winne, 1995).They also are adept at modifying their learning be-haviors in response to shifting situational demands or con-ditions(Zimmerman,1989).In short,self-regulated learners have high levels of knowledge about different cog-nitive learning strategies and have the ability to select,mon-itor,and regulate their use of those strategies when engaged in academic tasks.EDUCATIONAL PSYCHOLOGIST,38(4),189–205Copyright © 2003, Lawrence Erlbaum Associates, Inc.Requests for reprints should be sent to Christopher A.Wolters,Depart-ment of Educational Psychology,University of Houston,491Farish Hall, Houston, TX77204–5029. E-mail: cwolters@REGULATION OF MOTIVATION AS ACOMPONENT OF SELF-REGULATEDLEARNINGMany models of self-regulated learning also presume that students manage aspects of the learning process in addition to their actual cognitive processing.Students’ability to control aspects of their motivation,more specifically,is thought to have an impact on their learning and achievement.Research examining self-regulation from a volitional perspective,for example,has emphasized students’efforts to increase their persistence or time on task(Corno,1993,2001;Kuhl,1985). Motivation has also been identified as one area of the learning process that students actively self-regulate within social cog-nitive models of self-regulated learning(Zimmerman,1994). In line with this view,Pintrich(2000;Garcia&Pintrich, 1994)described resource management or effort control as an important component of students’self-regulated learning. Finally,Boekearts(1995,1997)depicted the active manage-ment of affective and motivational processes as an important part of self-regulated learning.In sum,there is some agree-ment in the literature that students may act to monitor and reg-ulate their motivation or the processes responsible for their motivation and that this form of self-regulation can ultimately have an impact on their learning and achievement.The purpose of this article is to evaluate the theoretical and empirical research concerning regulation of motivation to emphasize its importance to students’self-regulated learning. To achieve this goal the remainder of the article is divided into four sections.In the first section,a working definition of regulation of motivation is provided.In the second section, the theoretical distinctions between regulation of motivation and motivation,volition,and metacognition are evaluated.In the third section,this conceptual understanding is used to identify and describe a number of strategies that students might use to regulate their motivation within academic con-texts.As part of this discussion,the empirical evidence relat-ing these strategies to students’choice,effort,cognitive engagement,or academic performance is reviewed.Finally, in the fourth section,several key issues related to regulation of motivation are identified as a guide for additional research.REGULATION OF MOTIVATION AND ITSRELATION TO OTHER ASPECTS OFSELF-REGULATED LEARNINGTo define regulation of motivation,the meaning of achieve-ment motivation itself needs to be clarified.Behaviorally, theories of motivation attempt to explain outcomes such as students’choice of activities,the intensity of their effort or level of cognitive engagement within those activities,and their persistence at those activities(Graham&Weiner,1996; Pintrich&Schrauben,1992;Winne&Marx,1989).His-torically,efforts to understand and explain these behavioral outcomes have relied on factors that include instincts,inter-nal drives or traits,behavioral associations,and psychoanalytic forces(Graham&Weiner,1996;Pintrich& Schunk,2002).In contrast,more contemporary models of motivation emphasize the importance of cognitive constructs such as students’causal attributions,perceptions of self-com-petence,value,interest,feelings of self-determination,and reasons for engaging in an activity(Graham&Weiner,1996; Pintrich & Schunk, 2002).From a cognitive perspective,motivation can be charac-terized as either a product or a process(Winne&Marx, 1989).When viewed as a product or state,motivation refers to a student’s willingness to engage in and persist at a task.At any particular time,students have a level of motivation that they experience phenomenologically and that influences their choice,effort,and persistence regarding a particular ac-tivity.For example,students can experience the phenomenological state of being interested,feeling self-effi-cacious,or wanting to master an activity.Motivation also can be viewed as the process or processes that account for stu-dents’level of motivation or goal-directed behavior(Pintrich &Schunk,2002).From this perspective,motivation refers not just to an end state but also to the means through which that state is determined,and more generally to the cognitive processes that govern students’choice,effort,and persistence (Winne&Marx,1989).For instance,motivation would in-clude the processes that account for a student being inter-ested,feeling self-efficacious,or wanting to master a task and the impact of these states on students’behavior.Within this discussion,the term motivation is used broadly to refer to both students’level of motivation as well as the processes that account for that level of motivation.Consistent with this inclusive view of motivation,regula-tion of motivation can be described as the activities through which individuals purposefully act to initiate,maintain,or supplement their willingness to start,to provide work toward, or to complete a particular activity or goal(i.e.,their level of motivation).This form of regulation is achieved by deliber-ately intervening in,managing,or controlling one of the un-derlying processes that determine this willingness(i.e.,the processes of motivation).Regarding behavior,the regulation of motivation(or motivational regulation)encompasses those thoughts,actions,or behaviors through which students act to influence their choice,effort,or persistence for aca-demic tasks.Consistent with general descriptions of strate-gies(Alexander et al.,1998),a strategy for the regulation of motivation(or motivational regulation strategy)can be char-acterized as a procedure used by individuals in a purposeful and willful manner to influence their motivation.To the ex-tent that such a strategy is instigated,monitored,and directed by a student,it also can be identified as a self-regulation strat-egy and one factor in determining whether that student is a self-regulated learner.As conceptualized here,motivational regulation is one process that operates within the larger system of self-regu-190WOLTERSlated learning.As such it is related to but conceptually distinct from other processes considered critical to self-regulated learning including motivation, volition, and metacognition. Distinguishing Between Motivation andRegulation of MotivationAlthough deeply interrelated,the process of motivational regulation can be conceptually distinguished from the pro-cesses that account for motivation itself.Most notably these two processes can be differentiated based on the awareness and purposefulness of students’thoughts and actions. Self-regulated learners are considered to be consciously and intentionally engaging various regulatory strategies to ac-complish specific learning goals,especially in the initial stages of using a strategy(Pintrich,2000;Schunk,2001; Zimmerman,2000).Consistent with this view,regulation of motivation concerns only the thoughts and actions through which students deliberately try to influence their motivation regarding a particular activity.Cognitive models of motivation,in contrast,do not typi-cally propose that students necessarily are aware of the under-lying processes that determine their motivation or that they purposefully intervene in these processes.For example,attri-bution theory proposes a process in which the causal attribu-tions that students identify as responsible for their success or failure at a task sparks an emotional response and influences students’later expectations for success(Weiner,1986).To-gether these emotions and expectations influence students’willingness to engage in similar tasks encountered in the fu-ture.Students’understanding and active control over the attributional process is not necessary for these effects to be re-alized.In contrast,students must exhibit a conscious level of understanding and more active control to self-regulate this motivational process.Boekaerts(1992)described this distinc-tion as the difference between subjective control,meaning ac-tions influenced through beliefs and perceptions,and active control,meaning conscious intent to manipulate.Kuhl high-lights this difference by referring to the factors influencing the metalevel of decision making regarding one’s actions as executional preferences,while using the labels“motiva-tional”or“emotional”preferences for those factors influenc-ing the more traditional process of motivation(Kuhl& Kazen-Saad,1988;Kuhl&Kraska,1989).Theories of moti-vation emphasize the subjective control that various beliefs and attitudes have on students’choice,effort,and persistence, whereas the regulation of motivation concerns students’ac-tive control of the processes that influence these outcomes.This theoretical distinction between the process of motiva-tion and the regulation of motivation mirrors the division that can be drawn between students’cognitive processing and their regulation of cognition(Pintrich et al.,2000).As with this latter distinction,the difference between the process of motivation and the regulation of motivation can become somewhat fuzzy.For example,self-efficacy has been labeled a“self-regulatory process”and its role in students’motiva-tion has been described as the self-regulation of motivation (Schunk,1991;Zimmerman,Bandura,&Martinez-Pons, 1992).Self-efficacy does reflect a belief about the self and it does have a significant influence on motivation and ulti-mately on students’self-regulated learning.In line with the aforementioned distinction,however,this influence does not necessarily include any deliberate thoughts or actions by the individual.As an example,students may avoid activities be-cause they do not feel efficacious about completing them (Bandura,1997).This influence on choice,though,may not and may never have been consciously understood or con-trolled by the learner.Following the current understanding, therefore,the traditional influence of self-efficacy on stu-dents’choice,effort,or persistence would be considered mo-tivational,whereas only some awareness and intentional management of this process by the student would be consid-ered the regulation of motivation.Despite this theoretical distinction,motivation and the regulation of motivation are likely to have a complex and in-terdependent relation.The need to use a motivational regula-tion strategy may only be triggered when students experience problems with their ongoing level of motivation,learning,or performance.It is possible that students will sometimes begin and complete a task with a consistently high level of motiva-tion and thus may not experience any obstacles that interrupt their initiation,engagement,and persistence at the task.Dur-ing such times students are unlikely to engage any regulation strategies intended to influence their motivation.This reason-ing suggests that students who express highly adaptive moti-vational beliefs and attitudes may sometimes use motivational regulation strategies less frequently than stu-dents with less adaptive beliefs and attitudes may.In contrast to this rather ideal situation,students often have some positive level of motivation yet experience potential motivational obstacles as they are preparing for and complet-ing their academic work.For example,students may face boredom,difficulty in making progress,or distractions in the environment.Theoretically,the ability to regulate their moti-vation under these conditions should allow some students to overcome these problems and maintain a more productive level of engagement in the task.Hence,students who produc-tively regulate their motivation should experience fewer situ-ations in which they choose not to begin a task,provide inadequate effort,or disengage before a task is complete.Un-der these conditions,students’use of motivational regulation strategies should be positively associated with their motiva-tion, their effort, and their performance.Adding to the complexity of the relation between motiva-tion and the regulation of motivation is the fact that some ef-fort and thus some initial level of motivation are necessary to engage any regulatory strategy.Although it ultimately should result in an increased level of motivation,the regulation of motivation is also an effortful process that itself must be initi-REGULATION OF MOTIVATION191ated by some minimal willingness to complete a task.It seems doubtful that students who completely lack any expectation of success,who do not value successful completion of a task in the least,and who are not committed to finishing the task for any reason,will activate a strategy designed to ensure that the task is accomplished.From this perspective students must possess some minimum willingness to engage and complete a task or else when they encounter motivational problems they will fail to regulate their motivation and quit the task alto-gether.This assumption is supported by empirical evidence showing that students with more adaptive motivational be-liefs tend to report using some motivational regulation strate-gies more frequently (Wolters & Rosenthal, 2000).Overall,this line of reasoning suggests a theoretical rela-tion between students’motivation and motivational regula-tion that is reciprocal and perhaps curvilinear.This relation is reciprocal in that students’motivation affects their use of mo-tivational regulation strategies,while at the same time the use of motivational regulation strategies influences students’on-going motivation.It may be curvilinear because this relation is likely to be strongest among students with a moderate level of motivation,while weaker for students with very high or very low levels of initial motivation.Research that tests these assumptions empirically is needed to clarify and better estab-lish the nature of these hypothetical relations,and to explore how the regulation of motivation fits with specific models used to explain motivation.Distinguishing Between Regulation ofMotivation and MetacognitionLike motivation,metacognition is often viewed as a core ele-ment necessary for self-regulated learning(Butler&Winne, 1995;Pintrich et al.,2000;Zimmerman,1994).Historically, research on metacognition has roots that stretch into many ar-eas of psychology including work focused on cognitive de-velopment,memory,executive processing,and learning strategies(Brown,Bransford,Ferrara,&Campione,1983; Flavell,1979;Kluwe,1982;Pressley,Borkowski,&Schnei-der,1987).Perhaps because of this heterogeneous back-ground an exact and enduring definition of metacognition and its constituent processes has at times proven to be elusive (Baker,1994;Paris&Winograd,1990;Wellman,1983). Nevertheless,metacognition is most frequently described as consisting of at least two theoretically distinguishable com-ponents including regulation of cognition and knowledge of cognition(Brown et al.,1983;Flavell,1979;Pintrich et al., 2000; Schraw & Moshman, 1995).Narrowly defined,regulation of cognition describes stu-dents’efforts to monitor,control,or adjust their cognitive processing in response to shifting task demands or conditions (Baker,1994;Brown,1987).Activities typically viewed as efforts to regulate cognition include planning how to com-plete a task,selecting the cognitive strategies one will use,monitoring the effectiveness of the strategies one has chosen, and modifying or changing the cognitive strategies one is us-ing when problems are encountered(Pintrich et al.,2000; Schraw&Moshman,1995).Generally,the research on this facet of metacognition indicates that students who more ef-fectively regulate their cognitive strategy use tend to show more adaptive performance or achievement outcomes (Baker,1994;Butler&Winne,1995;Pressley et al.,1987; Schraw & Moshman, 1995).The regulation of motivation and the regulation of cogni-tion are conceptually similar except that the purpose,object, or target of these two regulatory activities is different.Strat-egies for the regulation of cognition are meant to affect stu-dents’use of cognitive learning strategies or how students are processing,constructing,or understanding the material with which they are interacting.In contrast,strategies for regulat-ing motivation ultimately are meant to affect students’will-ingness to process information,to construct meaning,or to continue working.Strategies for regulating motivation do not necessarily influence how students are completing activities, but why they are completing them,or for how long they are completing them.A student using a motivational regulation strategy,for instance,may be intentionally pushing herself to continue working on a task,but she is not necessarily modify-ing the cognitive activities she is using to complete it.She may be using memorization before as well as after engaging the motivational regulation strategy.Theoretically,strategies for regulating motivation and strategies for regulating cognition are closely related and may be used in conjunction with one another(Boekaerts,1997). For example,the aforementioned student,recognizing that memorization is not working,may decide to outline and an-swer adjunct questions.This type of change in cognitive strat-egies would be the result of a metacognitive process.At the same time the student may activate a strategy to regulate her motivation to sustain the effort needed to engage in this more effortful cognitive processing.Alternatively,a student recog-nizing that she is bored and frustrated with a reading may en-gage a strategy to increase her persistence while also changing to a form of cognitive processing that requires less effort.In short,though they can be distinguished conceptu-ally,the regulation of motivation and the regulation of cogni-tion are expressions of the same underlying self-regulatory system and likely work in tandem under many circumstances. Thus,it may be difficult to differentiate empirically between regulation that is motivational and regulation that is metacognitive in particular cases.Knowledge of cognition,the second component of metacognition,includes students’understanding or stored in-formation regarding the thinking and learning process.This aspect of metacognition has been differentiated based on whether the knowledge pertains to the person,to tasks,or to strategies,and into declarative,procedural,and conditional forms of knowledge(Baker,1994;Flavell,1979;Schraw& Moshman,1995).Students’knowledge of the thinking and192WOLTERSlearning process is viewed as an important prerequisite for the regulatory aspects of metacognition and thus for students’self-regulated learning (Pintrich et al., 2000).In a similar fashion,students’regulation of motivation is likely to be dependent on their metalevel knowledge regard-ing motivation.This knowledge might include information regarding their current level of motivation,the processes that impact their motivation,and the factors that affect motivation more generally.In other words,the influence of students’metamotivational knowledge on their use of motivational regulation strategies would mirror the impact of students’metacognitive knowledge on their use of strategies for regu-lating cognition.In theory,students would need to have de-clarative,procedural,and conditional knowledge pertaining to strategies for regulating motivation to use them effectively. Metalevel knowledge about motivation would also be impor-tant when making decisions about which motivational regula-tion strategy would be most effective within a particular context,or when making decisions about how to modify a strategy to fit a specific situation.Students who lack the req-uisite knowledge of motivation may fail to use a particular strategy for regulating motivation,or they may fail to use it effectively.Previous research provides some insight into the impor-tance of students’metalevel knowledge regarding motiva-tion.For example,developmental changes in students’knowledge or beliefs about effort and its relation to ability can influence their level of motivation and perhaps their self-reg-ulated learning more generally(Wigfield,Eccles,& Rodriquez,1998).Still,motivational research has tended to focus on beliefs and attitudes that influence motivation through subjective control rather than on knowledge that is important for the active control of motivation(Boekaerts, 1992).For instance,much research has examined develop-mental changes in how competent students feel about com-pleting academic work and how these changes relate to students’motivation and achievement(Wigfield et al.,1998). In contrast,studies that focus on whether students are aware of these changes—or are aware of how their feelings of com-petence impact their choice,effort,and persistence at aca-demic tasks—are less readily available.Generally,additional research is needed that directly investigates the thoughts or beliefs that can be categorized as knowledge of motivation, when this knowledge develops,and how this knowledge in-fluences students’ cognition and motivation. Distinguishing Between Regulation ofMotivation and VolitionThe notion of will or volition appeared early in the history of psychology(e.g.,Ach,1905;James,1890)although its prom-inence has waxed and waned especially regarding explaining behavior within academic settings(see Corno,2001;Kuhl& Beckmann,1985,for reviews).More recently,volition has been emphasized by Kuhl(1985)and Corno(2001)as a way of understanding students’self-regulated learning.In fact,the regulation of motivation discussed up to this point appears similar and indeed has much in common with volitional ac-counts of self-regulation.Regulation of motivation and voli-tion both convey the importance of understanding how stu-dents manage disruptions in goal-directed behaviors.For instance,each construct can be used to explain how students manage distractions or other problems that might interfere with the timely completion of their academic work.In addi-tion,regulation of motivation and volition both recognize as significant the distinction between motivational processes and students’ability to regulate or purposefully control those processes.Finally,explanations of the regulation of motiva-tion and volition are similar in that they both highlight the fact that the management of goal-directed behavior is accom-plished through the use of various strategies that,at least ini-tially, are consciously controlled by the learner.Despite these commonalities,students’management of their motivation is conceptualized and presented in this re-view from a more general social cognitive perspective of self-regulated learning.One reason for adopting this view of self-regulated learning is that it assumes a more fluid,ongo-ing interaction between students’motivational,cognitive, and regulatory processing(Bandura,1986;Schunk,2001; Zimmerman,2000).Volitional perspectives on self-regula-tion emphasize the distinction between motivational pro-cesses or those that account for the selection of which goals to pursue,and volitional processes that are important for pro-tecting the intention to pursue that goal(Corno,2001;Kuhl, 1985).For example,the transition from processing that is mo-tivational to processing that is volitional has been depicted as crossing the Rubicon,a change that is difficult to undo (Corno,1993).Social cognitive views also acknowledge that the self-regulation process can be described as including fore-thought,performance,and self-reflection phases (Zimmerman,2000).From a social cognitive perspective, however,the distinction among these phases is viewed as less absolute,and the interaction among the processes within each phase more dynamic.For example,self-efficacy as a motiva-tional process is thought to be important within each of these phases(Schunk,2001).This more dynamic view is advanta-geous for understanding the regulation of motivation because many of the strategies described in the following section ap-pear to operate across the forethought,performance,and self-reflection phases of task completion.A second reason for using a social cognitive framework to understand the regulation of motivation is that this framework makes it easier to tie this process to contempo-rary views of motivation.Cognitive views of motivation are not limited to explaining students’selection of particular goals,or to their choice of activities or behaviors.Rather, cognitive views of motivation extend into the activities as-sociated with completing a task to understand,explain,and predict students’quality or intensity of engagement and on-REGULATION OF MOTIVATION193。
