pep人教版五年级下册英语第一单元单元整体教学课堂实录全文共6篇示例，供读者参考篇1Unit 1: A Bright StartToday was our first English class of the new semester. Miss Li walked in with a big smile on her face. "Good morning, class! How was your vacation?" she asked cheerfully. We all replied with a loud "Great!"Miss Li clapped her hands together. "Wonderful! I'm so glad you all had a nice break. Now, who can tell me what we learned about in our last unit before the vacation?"Quite a few hands shot up. Miss Li called on Xiao Ming. "We learned about different summer jobs and how to describe them," he answered."Very good, Xiao Ming!" Miss Li praised him. "This unit, we're going to learn about setting goals and making plans for the school year ahead. Can anyone tell me what a goal is?"I raised my hand eagerly. Miss Li nodded at me. "A goal is something you want to achieve or accomplish," I explained."Excellent definition!" Miss Li said. "Setting goals is very important for success in life. Let's start with a fun activity - I want each of you to think of one goal you have for this school year. It can be anything - getting better grades, joining a club, or even something simple like reading more books."We all thought hard for a few minutes. Then Miss Li asked us to share our goals. There were all sorts of creative ones - Xiao Li wanted to win a writing contest, Xiao Zhang hoped to get on the football team, and Xiao Wang just wanted to be more organized with his homework.After we went around the class, Miss Li said, "Those are all wonderful goals! But how can we make sure we actually achieve them? The key is to make a plan with specific steps."She wrote an example on the board:Goal: Get an A in English classPlan:Pay attention in class and ask questionsDo all homework assignmentsReview material regularlyGet help from parents or teacher if struggling"Can you see how having a clear plan makes it much easier to work towards your goal?" Miss Li asked. We all nodded in agreement.Then it was our turn to make plans for our own goals. I decided my goal was to read 20 books this year, so my plan looked like:Read 30 minutes every night before bedBorrow books regularly from the libraryJoin the reading club at schoolAsk parents and teachers for book recommendationsOnce we had all written out our goals and plans, Miss Li had us get into small groups to discuss. "Share your goals with your group members, and see if they have any suggestions to improve your plans," she instructed.My group gave me some great ideas, like setting a reading timer on my desk and keeping a reading log. I also helped them refine their plans for joining sports teams and music clubs.As the class ended, Miss Li reminded us, "Don't forget to POST your goals and plans somewhere you'll see them every day! Staying motivated is so important. I'm excited to see what you all accomplish this year!"I could already tell this was going to be a productive semester. Having a clear goal and plan gave me a strong sense of purpose. I couldn't wait to start working towards becoming a reading superstar!篇2Hello Class! Today we are starting a new unit in our English textbooks – Unit 1: My Day. Miss Li seems really excited to teach us all about daily routines and schedules."Good morning students! I hope you all had a wonderful weekend," Miss Li begins with a big smile. "Who can tell me what the title of our new unit is?"I quickly raise my hand, eager to get started. "My Day!" I announce proudly when called on."Very good, Xiaoming. Does anyone know what this unit will be about?" Miss Li scans the classroom. Xuexue's hand shoots up."It's about our daily routines and schedules," she answers confidently."Excellent job, Xuexue! You're absolutely right," praises Miss Li. "In this unit, we'll learn vocabulary and phrases to talk about the activities we do each day, from when we wake up to when we go to bed at night."We all nod excitedly. Learning to describe our daily lives in English sounds really useful and fun!Miss Li continues, "Let's start by looking at the picture on page 12. What do you see?"I study the colorful illustration carefully. "I see a girl waking up and getting out of bed," I observe."Good eye, Xiaoming. And Fengfeng, what is she doing next?"Fengfeng points to the next picture. "She is brushing her teeth and getting ready for the day.""Wonderful! Then what happens after that, Dandan?" Miss Li gestures to the following images."Um, she eats breakfast...then leaves for school?" Dandan phrases it like a question, unsure.Miss Li smiles reassuringly. "You're on the right track. The pictures show her eating breakfast, packing her bag, and heading out the door to school. Very observant!"We spend the next few minutes reviewing the basic morning routine illustrated in the pictures, repeating the new vocabulary words like "wake up", "brush teeth", "eat breakfast", and so on. Miss Li has us all stand and act out the motions as we say each phrase.Next, Miss Li splits us into pairs to practice simple dialogues about our morning schedules using the new language from the pictures."Xiaoming, what time do you usually wake up?" Xuexue asks me.I scratch my chin, thinking. "I usually wake up at...7 o'clock in the morning.""Wow, that's early!" Xuexue responds. "I wake up at 7:30. Then what do you do after waking up?""Well, first I brush my teeth. Then I get dressed and eat breakfast - usually rice porridge with pickles!"Xuexue giggles at my breakfast choice. "I like toast with jam better. Do you have any other morning routines before leaving for school?"I nod enthusiastically. "Yes, I also pack my school bag and...oh! I almost forgot - I practice piano for 15 minutes too.""You're so diligent, Xiaoming!" Xuexue gives me a high-five. "I just watch cartoons until the last minute."We both laugh, then switch roles so I can ask Xuexue about her morning schedule. The practice dialogues are great writing and speaking practice.After letting us chat in pairs for a bit, Miss Li regains our attention. "Alright class, let's move on to talking about our afternoon schedules after school gets out. What kinds of activities do you all do in the afternoon and evening?"Handhands raise all around the room, everyone eager to share. "I do my homework!" "I have piano lessons." "I play basketball." "My grandma cooks dinner for us."Miss Li listens with a smile, nodding along. "Those all sound like wonderful afternoon activities. In this unit, we'll learn to talk about not just our morning routines, but everything we do until bedtime at night."The rest of class flies by as we review vocabulary for common after-school activities, meals, chores, hobbies, and how to describe our nightly routines too. We practice asking each other questions like "What do you do after dinner?" and "What time do you go to bed?". By the end, I feel like I've learned so many new English phrases to discuss my daily schedule!As the bell rings for class to be over, Miss Li reminds us, "Don't forget to review the vocabulary from today's lesson at home. Next class, we'll practice putting all the new morning, afternoon, and evening phrases together to describe a full day's routine. I'm excited to hear all about your daily lives in English! Class dismissed."I can't wait for the next lesson. Describing my typical day at school sounds really fun and useful. I'm glad we're starting this new unit!篇3Unit 1: My HobbiesTeacher: Good morning, class! How are you all doing today?Students: Good morning, Miss Lee!Teacher: Wonderful! Today, we're going to start a new unit called "My Hobbies." Can anyone tell me what a hobby is?Alice: A hobby is an activity that we do for fun in our free time.Teacher: Excellent, Alice! Hobbies are a great way to relax and enjoy ourselves after a long day of studying and working hard. Now, let's look at the first dialogue in our textbook.(The teacher plays the audio dialogue between two friends discussing their hobbies.)Teacher: Did you understand what they were talking about?Tom: Yes, Miss Lee. One of them likes playing badminton, and the other one likes reading comic books.Teacher: Very good, Tom. Playing badminton and reading comics are both hobbies that the characters enjoy. Can anyone give me an example of their own hobby?Mary: I like dancing! I take ballet classes every weekend.Teacher: That's wonderful, Mary. Dancing is a fantastic hobby that helps you stay active and express yourself creatively. Who else would like to share their hobby?(Several students raise their hands and share their hobbies, such as playing soccer, painting, and learning to play the guitar.)Teacher: It's great to see that you all have such diverse and interesting hobbies. Hobbies not only bring us joy and relaxation, but they can also teach us valuable skills and help us make new friends who share our interests.Now, let's practice some vocabulary related to hobbies. Can anyone tell me what "collection" means?John: A collection is a group of things that someone gathers and keeps, like stamps or coins.Teacher: Excellent, John! Collecting is a popular hobby for many people. And what about "craft"?Amy: A craft is an activity where you make things with your hands, like knitting or woodworking.Teacher: Well done, Amy. Crafts are a great way to express your creativity and make unique items.(The teacher continues to introduce and explain vocabulary related to hobbies, such as "masterpiece," "amateur," "professional," and "exhibition.")Teacher: Alright, class, now it's time for a fun activity. I've prepared a worksheet with pictures of different hobbies. In pairs, I want you to discuss the hobbies and write down the names and any vocabulary words you know related to each one.(The students work in pairs on the activity, discussing and writing about the different hobbies depicted in the pictures.)Teacher: Time's up! Let's share what you've written. Who would like to go first?(Several pairs of students take turns presenting their work and discussing the hobbies they identified.)Teacher: Great job, everyone! You've all shown a wonderful understanding of hobbies and the vocabulary we've learned today. For homework, I'd like you to write a short paragraph about your favorite hobby, using at least three new vocabulary words from this unit.Remember, hobbies are not only fun but also help us develop new skills and interests. I hope you all continue to explore and enjoy your hobbies outside of school.Class dismissed!Students: Thank you, Miss Lee!篇4Hi everyone! I'm so excited to share my experience from our recent English class. We started a brand new unit, and it was super fun! Let me tell you all about it.Miss Li, our English teacher, greeted us with her usual warm smile. "Good morning, class! Are you ready to embark on a new adventure?" We all nodded eagerly, curious to know what she had in store for us."Today, we're going to explore the first unit of our new textbook," she announced. "It's called 'My Favorite Things,' and we'll learn how to talk about our likes and dislikes, hobbies, and personal preferences."First up, Miss Li introduced some new vocabulary words. We learned words like "favorite," "hobby," "collection," and "interest." She showed us pictures and asked us to repeat the words after her. It was a fun way to learn!Then, we moved on to a dialogue between two characters, Amy and Tom. They were discussing their favorite things and hobbies. Miss Li played the audio, and we listened carefully."Amy loves playing the piano and collecting stickers," Tom said."That's cool! I like playing basketball and reading comics," Amy replied.After listening, Miss Li asked us questions to check our understanding. "What is Amy's favorite hobby?" she inquired. I raised my hand excitedly and answered, "Amy's favorite hobby is playing the piano!"Next, we practiced the dialogue in pairs. I partnered up with my best friend, Lily. We took turns playing the roles of Amy and Tom, pretending to talk about our favorite things. It was hilarious when Lily said her favorite hobby was eating ice cream!Miss Li then introduced a new grammar point: the present simple tense. We learned how to form sentences like "I like playing football" and "She doesn't like reading books." We did some exercises to practice using the present simple tense correctly.After the grammar lesson, it was time for a fun activity! Miss Li divided us into groups, and each group had to create a poster about their favorite things. My group chose to make a posterabout our favorite sports. We drew pictures, wrote captions, and even included some interesting facts.When we finished, each group presented their poster to the class. It was amazing to see the variety of interests and hobbies represented. From collecting rocks to playing video games, we all had unique favorites!Finally, Miss Li asked us to write a short paragraph about our favorite things. I wrote about my love for drawing and how I enjoy creating art with crayons and colored pencils. I even drew a little picture to go with my paragraph.As the class came to an end, Miss Li praised us for our hard work and enthusiasm. "You all did a fantastic job today!" she said. "I'm so proud of you for embracing this new unit with such energy and creativity."We couldn't wait for the next English lesson! Learning about our favorite things was not only fun but also helped us express ourselves better in English. I can't wait to see what other exciting adventures await us in this unit!篇5Teacher: Good morning, class! How was everyone's weekend?Students: Good morning, Mrs. Smith! My weekend was great, I went to the park with my family.Teacher: That's wonderful to hear! Today we're starting a new unit in our English textbook. Can anyone tell me what the unit is about from looking at the title and pictures?Student 1: I think it's about different countries and cultures around the world. I see pictures of famous landmarks like the Eiffel Tower and the Great Wall of China.Teacher: You're absolutely right, Sarah. This unit is called "A World of Wonders" and we'll be learning about diverse cultures, customs, and places. Let's start by looking at the first lesson - "Welcome to My Home Country." Who can read the first paragraph?Student 2: "Hello, my name is Miguel. I'm from a beautiful country called Mexico..."Teacher: Great job, Johnny. Mexico is indeed a fascinating country with rich history and traditions. The reading talks about some famous Mexican foods like tacos and enchiladas. Has anyone tried authentic Mexican cuisine before?Student 3: Yes, my family loves Mexican food! We sometimes go to this restaurant that serves the most delicious burritos and guacamole.Teacher: Wonderful, food is such an important part of culture. Now, let's look at some of the new vocabulary words we'll learn in this unit...(continues reviewing vocabulary)A few days later...Teacher: Okay, class, who can tell me what we learned about in yesterday's reading?Student 4: We read about the Day of the Dead festival that's celebrated in Mexico. It's when people honor their deceased family members with special altars and offerings.Teacher: That's right, Emma. The Day of the Dead is a very unique and meaningful tradition. Today, we'll watch a short video that shows how it is celebrated. Pay close attention...After the video...Teacher: What did you all think of that festival? Did anything surprise you?Student 5: I was surprised to see so many skeletons and skull decorations! In my culture, we don't really have celebrations involving things like that.Teacher: That's an excellent point, Jack. Different cultures have different perspectives and customs surrounding death and the afterlife. The skull imagery in Day of the Dead celebrations represents a light-hearted, positive view of death rather than something morbid or scary.We then spent some time discussing cultural perspectives and misconceptions. Towards the end...Teacher: Well, I'm impressed with how thoughtful and open-minded you all have been while learning about Mexican culture. Let's give ourselves a hand for being such great cultural ambassadors!Students:clappingTeacher: Next week, we'll explore some other fascinating countries and cultures by reading stories, watching videos, and even trying our hand at some traditional arts and crafts. I can't wait!Student 6: Me neither, Mrs. Smith! I'm really enjoying learning about different cultures in this fun new unit.篇6Today in English class, we started a new unit all about animals. Miss Li walked in carrying a big box full of stuffed animal toys. "Good morning, class! Can anyone guess what we'll be learning about this unit?" she asked with a smile.Xiaoming's hand shot up. "Animals?" he guessed."Very good, Xiaoming!" Miss Li praised him. She pulled out a fuzzy brown bear from the box. "This unit is called 'A World of Animals.' We're going to learn all about different kinds of animals and where they live."She reached back into the box and pulled out a plastic snake.A few girls squealed and laughed. "Don't worry, it's not real!" Miss Li assured us. "We'll start by learning how to describe an animal's appearance and characteristics."First, Miss Li had us open our textbooks to the vocabulary list on pages 4 and 5. There were words like "fur", "feathers", "scales", and "patterns." She held up each stuffed animal toy and we repeated the words that described what it looked like. Theelephant had gray wrinkly skin and big floppy ears. The zebra was black and white with stripes.Next, we listened to a recording about some kids visiting the zoo. They described seeing all the different animal exhibits. Miss Li paused the recording sometimes and asked us comprehension questions like "What did the girl say about the kangaroos?" It was a little tricky understanding everything at first, but I'm getting better at listening to English.After that, Miss Li put us into groups of four. Each group had to work together and make a poster about one particular animal. My group picked the panda! Lili looked up facts about pandas online while Dandan and I drew a big picture of a panda bear. We had to use the new vocabulary words to describe what pandas look like and what they can do. Dandan wrote "Pandas have black fur around their eyes and ears." I added "They have white fur on the rest of their body."When we presented our posters, Miss Li pointed out great examples of how we used descriptive language. Xiaoming's group did an awesome job on their poster about eagles. They wrote "Eagles have sharp curved beaks and sharp talons for gripping prey."Towards the end of class, Miss Li introduced some of the readings we'll do during this unit. One story is about a rainforest explorer who discovers a new species of frog. Another one takes place at a marine biology camp where the characters learn all about life in the ocean. I can't wait to read them!For homework tonight, we have to look over the vocabulary words again and write five sentences using them. We also have to fill out an activity sheet that has pictures of different animals, and we need to write what they look like underneath each picture.I feel like I already learned so much today! This is going to bea really interesting and fun unit. Studying different animals will make English class way more exciting than just learning grammar rules and vocabulary lists. I'm looking forward to learning more cool facts about animals and how to talk about them in English.。

小学英语下册集体备课活动记录范文全文共3篇示例，供读者参考小学英语下册集体备课活动记录范文1为进一步提高我校小学英语教师教学能力，发扬我校小学英语教师的团队合作和探究精神，开展好小学英语教学工作，在立足个人备课的基础上，加强小学英语集体备课。

为了切实提高集体备课的实效性，将集体备课活动落到实处，制定如下工作一、工作重点1、认真学习小学英语新课程标准和如何应用小学英语空中课堂资源，优化教学方式，提高课堂教学质量。

2、通过集体备课，充分挖掘教师们的教育教学潜能，有效地整合教育教学资源，提高教育教学质量，促进教师的专业发展。

二、工作措施1、在中心学校的组织和领导下，全镇小学英语教师间周一次，分年级进行集体备课活动，组长做好考勤记录。

2、为了减少盲目性，开学初的第一次集体备课，要向备课组成员明确本学期集体备课工作的具体要求，解读集体备课工作计划，安排好每一次备课内容和中心发言人，让每位教师都心中有数，使每次集体备课都有目的性针对性和实效性。

3、每次集体备课，组内教师轮流做中心发言人，提前书写好自己要研究的教学设计和教学中的.困惑并在个人说明的基础上，全组成员进行交流讨论，最终拿出最佳教学方案。

4、组内教师要跟踪看课，反馈集体备课成果，做好听课笔记，并在下一次活动中加以改进。

三、具体实施措施1、严格执行“个人粗备-----集体齐备-----个人细备-----反思复备”的步骤。

备课依据：①三定：定集体备课课题，定中心发言人，定教学进度。

②四统一：统一单元教学目的，统一教学重难点，统一课时分配，统一单元评价测试。

③五备：备课标，备教材，备教学手段，备教法，备学法。

④五点：重点、难点、知识点、能力点、教育点。

2、备课组成员必须在集体备课前先行备好简案，以及在中心想好自己的设想。

3、中心发言人在集体备课前要深入钻研教材和大纲，反复阅读教学参考书及积极查找相关资料，为发言谈做好充分的准备。

中心发言人的辅导内容应包括以下内容：①教材简介：含教材内容、特点、教学目标、重点、难点、教具准备、课时安排等。

五年级英语备课组活动记录一、活动主题。

提高五年级英语课堂教学效率与学生综合语言运用能力。

二、活动时间。

[具体日期]三、活动地点。

学校会议室。

四、参与人员。

五年级英语备课组全体教师。

五、活动内容。

1. 教材分析。

- 主备教师首先对人教版五年级英语教材进行整体分析。

指出本册教材重点在于巩固一般现在时的用法，同时增加了一些复杂的词汇和句型结构。

例如，在Unit 3中，学生需要掌握描述日常活动的短语，像“do morning exercises”“have English class”等，并且能够用一般现在时的句型“He/She often...”来描述他人的日常活动。

- 大家共同讨论教材中的难点内容，认为对于一些语法概念，如第三人称单数动词的变化，学生理解起来可能会有困难。

像“go - goes”“do - does”的变化规则，需要通过大量的实例和练习让学生掌握。

2. 教学方法研讨。

- 一位教师分享了情景教学法在英语课堂中的应用。

以Unit 2 “My week”为例，可以创设学校课程安排的情景，让学生在真实的语境中学习有关星期和课程的词汇与句型。

在这个情景中，教师可以利用教室的课程表，让学生进行问答练习，如“What do you have on Monday?”“I have Chinese, English and music.”- 另一位教师提出采用游戏教学法来提高学生的学习兴趣。

比如在复习单词时，可以玩“单词接龙”游戏。

教师先说出一个单词，然后学生以前一个单词的最后一个字母为开头说出下一个单词。

这个游戏可以在小组内进行竞赛，激发学生的竞争意识，从而更积极地参与到单词学习中。

- 大家还讨论了如何在教学中运用多媒体资源。

例如，在教授有关自然景观的词汇时，可以播放一些美丽的自然风景视频，如山脉（mountains）、河流（rivers）等，让学生在观看视频的同时学习单词，增强视觉记忆效果。

3. 作业设计。
