2016年江西师范大学考研教育硕士(Ed.M)教育综合真题试卷(题后含答案及解析)题型有:1. 名词解释题 2. 简答题 3. 论述题1.教育目的正确答案:教育目的即指教育要达到的预期结果,反映为教育在人的培养规格标准、努力方向和社会倾向性等方面的要求。
狭义的教育目的特指一定社会(国家或地区)为所属各级各类教育人才培养所确立的总体要求;广义的教育目的是指对教育活动具有指向作用的目的领域,含有不同层次预期实现的目标系列。
它不仅标志着一定社会(国家或地区)对教育培养人的要求,也标示着教育活动的方向和目标,是教育活动的出发点和归宿。
2.认知发展阶段正确答案:认知发展阶段是著名教育心理学家皮亚杰提出的一个概念。
他将儿童和青少年的认知发展划分为四个阶段:感知运动阶段、前运算阶段、具体运算阶段和形式运算阶段。
他认为所有的儿童都会依次经历这四个阶段,新的心智能力的出现是每个新阶段到来的标志,而这些新的心智能力使得人们能够以更为复杂的方式来理解世界;虽然不同的儿童以不同的发展速度经历这几个阶段,但是都不可能跳过某一个发展阶段。
3.动作技能正确答案:动作技能指通过练习巩固下来的、自动化的、完善的动作活动方式。
动作技能的理解与形成过程是通过领悟和练习逐步掌握某种动作操作程序的过程。
复杂运动技能的形成,一般要经历认知阶段、分解阶段、联系定位阶段、自动化阶段等四个主要阶段。
4.班级授课制正确答案:班级授课制是一种集体教学形式。
它把一定数量的学生按年龄与已有知识水平编成固定的班级,根据周课表和作息时间表,安排教师有计划地向全班学生集体上课。
在班级授课制中,同一个班的每个学生的学习内容与进度必须一致,且开设的各门课程,特别是在高年级,通常由具有不同专业知识的教师分别担任。
其注重集体化、同步化、标准化,长于向学生集体教学,但拙于照顾学生的个别差异、对学生进行个别指导,不利于培养学生的兴趣、特长和发展他们的个性。
5.教育行动研究正确答案:教育行动研究是在实际情景中,由实际工作者和专家共同合作,针对实际问题提出改进计划,通过在实践中实施、验证、修正而得到研究结果的一种研究方法。
2016年经济类专业学位考试《综合能力》真题(总分:100.00,做题时间:90分钟)一、逻辑推理1.巴西赤道雨林的面积每年以惊人的比例减少,引起了全球的关注。
但是,卫星照片的数据显示,去年巴西雨林面积的缩小比例明显低于往年。
去年,巴西政府支出数百万用以制止滥砍滥伐和防止森林火灾。
巴西政府宣称,上述卫星照片的数据说明巴西政府保护赤道雨林的努力取得了显著成效。
以下哪项如果为真,最能削弱巴西政府的言论?(分数:2.00)A.去年巴西用以保护赤道雨林的财政投入明显低于往年。
B.与巴西毗邻的阿根廷国的赤道雨林的面积并未缩小。
C.去年巴西的旱季出现了异乎寻常的大面积持续降雨。
√D.巴西用于雨林保护的费用只占年度财政支出的很小比例。
E.森林面积的萎缩是全球性的环保问题。
【解析】题干由去年巴西雨林面积的缩小比例明显低于往年,推出巴西政府保护赤道雨林的努力取得了显著成效。
C项为真说明巴西热带雨林面积缩小比例减少的原因是持续降雨,属于另有他因,削弱了题干推理。
故答案选C。
2.科学家研究发现,超过1 000个小行星经常穿越地球轨道。
即使小行星撞击地球的概率几乎可以忽略不计,但由于撞击将带来灾难性的后果,应尽可能降低撞击概率。
避免撞击的办法是使用核武器摧毁小行星,因此将核武器储存在空间站以备不时之需是有必要的。
科学家的推断会导致如下哪个推论?(分数:2.00)A.核武器是目前人类可知的唯一阻止小行星撞地球的方法。
B.空间站应当部署核武器。
√C.小行星撞击地球的事件尚未发生。
D.小行星撞击地球的概率极低。
E.为了防止小行星撞击地球,没有理由拒绝使用核武器。
【解析】题干中科学家的推断是将核武器储存在空间站以备不时之需是有必要的。
由此出发,会导致的推论必然涉及空间站与核武器之间的关系,选项中只有B项符合。
A、E两项过于绝对,C、D两项均为题干内容的复述,而非推论。
故答案选B。
3.要使中国足球队真正能跻身世界强队,至少必须解决两个关键问题:一是提高队员基本体能,二是讲究科学训练。

Students Students Students without without without experience experience experience can can can catch catch catch up up up after after after a a a few few few introductory introductory introductory courses, courses, courses, said said said Tom Tom Cortina, the assistant dean at Carnegie Mellon ‟s School of Computer Science. However, However, Cortina Cortina Cortina said, said, said, early early early exposure exposure exposure is is is beneficial. beneficial. beneficial. When When When younger younger younger kids kids kids learn learn learn computer computer science, they learn that it ‟s s not just a confusing, endless string of letters and numbers not just a confusing, endless string of letters and numbers – but a tool to build apps, or create artwork, or test hypotheses. It ‟s not as hard for them to transform their thought processes as it is for older students. Breaking down problems into bite-sized chunks and using code to solve them becomes normal. Giving more children this training could increase the number of people interested in the field and help fill the jobs gap, Cortina said. Students also benefit from learning something about coding before they get to college, where introductory computer-science classes are packed to the brim, which can drive the less-experienced or-determined students away. The The Flatiron Flatiron Flatiron School, School, School, where where where people people people pay pay pay to to to learn learn learn programming, programming, programming, started started started as as as one one one of of of the the the many many coding boot camps that that‟‟s become popular for adults looking for a career change. The high-schoolers high-schoolers get get get the the the same same same curriculum, curriculum, curriculum, but but “we we try try try to to to gear gear gear lessons lessons lessons toward toward toward things things things they they they‟‟re interested in,” said Victoria Friedman, an instructor. For instance, one of the apps the students are developing suggests movies based on your mood. The students in the Flatiron class probably won‟t drop out of high school and build the next Facebook. Programming languages have a quick turnover, so the “Ruby on Rails ” language they learned may not even be relevant by the time they enter the job market. But the skills they learn – how how to to to think think think logically logically logically through through through a a a problem problem problem and and and organize organize organize the the the results results – apply apply to to to any any any coding coding language, said Deborah Seehorn, an education consultant for the state of North Carolina. Indeed, the Flatiron students might not go into IT at all. But creating a future army of coders is not the sole purpose of the classes. These kids are going to be surrounded by computers-in their pockets ,in their offices, in their homes –for the rest of their lives, The younger they learn how computers think, how to coax the machine into producing what they want –the earlier they learn that they have the power to do that –the better. 21. Cortina holds that early exposure to computer science makes it easier to _______ A. complete future job training B. remold the way of thinking C. formulate logical hypotheses D. perfect artwork production 【答案】B 22. In delivering lessons for high - schoolers , Flatiron has considered their________ A. experience B. interest C. career prospects D. academic backgrounds 【答案】B 23.

But But But one one one specific specific specific complaint complaint complaint is is is made made especially mournfully : There There‟‟s never any time to read. What makes the problem thornier is that the usual time-management techniques don ‘t seem sufficient. The web ‟s full of articles offering tips on making time to read:” Give up TV ” or “Carry a book with you at all times.” But in my experience, using such methods to free up the odd 30 minutes minutes doesn doesn doesn‟‟t t work. work. work. Sit Sit Sit down down down to to to read read read and and and the the the flywheel flywheel flywheel of of of work-related work-related work-related thoughts thoughts thoughts keeps keeps spinning-or spinning-or else else else you you you‟‟re re so so so exhausted exhausted exhausted that that that a a a challenging challenging challenging book book book‟‟s s the the the last last last thing thing thing you you you need. need. need. The The modern modern mind, mind, mind, Tim Tim Tim Parks, Parks, Parks, a a a novelist novelist novelist and and and critic, critic, critic, writes, writes, writes, ““is is overwhelmingly overwhelmingly overwhelmingly inclined inclined inclined toward toward communication …It It is is is not not not simply simply simply that that that one one one is is is interrupted; interrupted; interrupted; it it it is is is that that that one one one is is is actually actually actually inclined inclined inclined to to interruption.interruption.”” Deep Deep reading reading reading requires requires requires not not not just just just time, time, time, but but but a a a special special special kind kind kind of of of time time time which which which can can can‟‟t t be be obtained merely by becoming more efficient. In fact, “becoming more efficient ” is part of the problem. Thinking of time as a resource to be be maximized maximized maximized means means means you you you approach approach approach it it it instrumentally, instrumentally, instrumentally, judging judging judging any any any given given given moment moment moment as as as well well well spent spent only in so far as it advances progress toward some goal. Immersive reading, by contrast, depends on being willing to risk inefficiency, godlessness, even time-wasting. Try to slot it as a to-do list item and you ‟ll manage only goal-focused reading-useful, sometimes, but not the most fulfilling kind. “The The future future future comes comes comes at at at us us us like like like empty empty empty bottles bottles bottles along along along an an an unstoppable unstoppable unstoppable and and and nearly nearly nearly infinite infinite conveyor belt,” writes Gary Eberle in his book Sacred Time, and “we feel a pressure to fill these different-sized bottles (days, hours, minutes) as they pass, for if they get by without being filled, we will have wasted them.” No mind-set could be worse for losing yourself in a book. So what does work? Perhaps surprisingly, scheduling regular times for reading. You‟d think this might fuel the efficiency mind-set, but in fact, Eberle notes, such ritualistic behavior helps us “step outside time ‟s flow ” into “soul time.” You could limit distractions by reading only physical books, books, or on or on single-purpose single-purpose e-readers. e-readers. e-readers. ““Carry Carry a a a book book book with with with you you you at at at all all all times times times”” can can actually actually actually work, work, too-providing you dip in often enough, so that reading becomes the default state from which you temporarily surface to take care of business, before dropping back down. On a really good day, it no no longer longer longer feels feels feels as as as if if if you you you‟‟re re ““making making time time time to to to read,read,read,”” but but just just just reading, reading, reading, and and and making making making time time time for for everything else. 31.
