1、新课标人教版初中英语八年级下册Unit 3 What were you doing when the UFO arrived ?Section A教学设计Section A 第一课时（一）学生分析：1.本班大部分学生英语学习兴趣浓厚，乐于积极参与唱歌，问答，游戏，调查及报告等活动，有一定的综合语言运用能力。2.有一小部分同学英语基础欠缺，小组合作中的互帮互助可以很好的解决这一问题。3.学生已经学习过现在进行时中的“be+doing” 结构，对过去进行时的理解和掌握有一定的帮助。4.学生课前已经预习过相关生词，为新授课的学习奠定了一定基础。（二）教材分析：1.本课是Unit3中的第一课时，需要完
2、成1a,1b,1c,2a,2b,2c的内容。2.本课的背景素材为UFO和外星人，能激发学生的学习兴趣。3.在本套教材的初一下册中，已经系统地学习了现在进行时和一般过去时，为本课中的过去进行时奠定了基础。4.本课时让学生熟悉运用was/were +doing 结构的基本用法及其特殊疑问句，为他们学习3a,3b,4和Section B打好基础。（三）教学目标：1. 语言知识目标：能熟悉运用was/were + doing的基本用法及其特殊疑问句能了解when和 while的用法区别。2. 语言技能目标：能谈论在过去某一时刻或某一段时间正在发生的事情。3. 情感目标：通过创设人文情景，学生亲身感受体

4、活动的录像，录音机，课堂练习表格（七）教学过程：Task 1: Leading in the topic by singing a song.Aims: Incite the students interest and lead in the topic.Teachers activity: Show the lyrics and lead the students to sing the song:Were you sleeping,Were you sleeping,When the teacher came in?When the teacher came in?Try to be be
5、tter.Try to be better.Hurry! Hurry! Hurry!Hurry! Hurry! Hurry!Students activity: learn by singing.在这pre-task阶段，通过让学生来学唱简单的英语歌曲，初步感知过去进行时，并通过强调过去进行时的结构来导入本课，从而激发了学生的学习兴趣和学习欲望，为一节成功的课做好了准备。Task 2: Learn some phrases of activities.Aims: Help the students learn the key words and get them ready for the n
6、ext task.Teachers activity: Present the phrases with pictures and help the students learn.Students activity: Learn the phrases by the pictures.Step:Show the students the pictures and ask them to read the phrases after the tape.Step:Tell the students to pay attention to their ing forms.仍然是pre-task阶段的
7、任务，学生通过生动形象的图片，截取的听力原文，兴趣盎然地学习了key words，激活了对完成以下任务非常有用的词汇，同时，通过对动词-ing形式的练习，为下面任务中对过去进行时的处理打下了基础。Task 3: Leading in the target language by listening to the tape.Aims: Practice the students listening skill and lead in the target language.Step: Ask students to read the phrases in activity 1b to get r
8、eady for listening.Step: Ask the students to circle what they will hear by listening to the tape.Step: Check the students answers by asking and answering like:-What was she doing when the UFO arrived?-She was standing in front of the library.Step: Pair work, ask the students to ask and answer with t
9、he target language with the help of the pictures in Task 2.在这一任务的设计中，既加强了对听力技巧的指导，又通过对听力答案的订正很自然地过渡到了对目标语言的对话练习中。Task 4: Retell a short story by Listening practice in activity 2a.Aims: Improve the students listening skill and oral English.Step: Lead the students to read the sentences in activity 2a
10、to make sure the students are familiar with the listening materials.Step: Ask the students to listen to the tape and number the statements in the order they hear them.Step: Check the students answers with the following words:First,landed onNext,got out ofThen,went intoAnd then,boughtFinally,visitedS
11、tep: Ask the students to practice retelling the short story with the help of the words.在这一任务的设计中，考虑到听力任务的难度不大，于是在听力结束之后又提高了任务难度，即根据听力信息来复述这则小故事，为第二课时中3a的学习奠定了基础。Task 5: Find the differences between “when” and “while” by listening and doing the exercises.Aims: Try to make the students learn the gramm
12、ar by doing themselves.Step: Ask the students to complete the sentences with “when” and “while” in activity 2b themselves before listening.Step: Ask the students to listen to the tape and check their answers.Step: Ask the students to read the sentences carefully and try to find the differences betwe
13、en “when” and “while”.Step: Make some of the students show their views about the grammar, and show the detailed explanation:When I got to the classroom, Mr. Li was talking to my classmates this morning.在表示过去的时间状语中,when后跟一般过去时。While Tom was doing his homework, his father was cooking.在表示过去的时间状语中,when后
14、跟一般过去时。在本环节中，并没有直接将语法项目呈现给学生，而是让学生通过自主探究，learning by doing,归纳出知识点，教师再做适当的点拨。这样的处理方式，会使学生对所学知识理解的更深刻，记忆的更牢固。Task 6: Using the grammar points by playing a game.Aims: Try to use the grammar points and incite the students interest.Step: Talk about the appearance of aliens with the students.Step: Ask two
15、 students to come to the blackboard and draw aliens.Step: Show some notes to the students and ask the students to do the activities as the notes tell them.Step: Ask the students to tell some sentences as the model given by the teacher:While they were drawing, I was walking around the classroom.在这一任务
16、的设计中，通过黑板上同学画神秘的外星人，座位上的同学做各种有趣的动作，极大地调动了学生的积极性和主动性，为“while”在过去进行时中的应用训练创设了绝佳的情景，让同学们在游戏中轻松掌握了知识点，体验到了成功的快乐。Task 7: The famous detective ConanAims: Develop the topic and evaluate the language out-put.Step: Watch a video of a party. (At the party, a girls handbag was robbed by a robber)Step: To make
17、the students sure that the teacher isnt the robber, play another video about what the teacher was doing at that time.Step: Monitor the survey.First, ask the students to work in groups and choose their group leader as Conan.Next, ask them to ask and answer in their groups as the model given:Conan: Wh
18、at were you doing at 8:00 yesterday evening?Student1: I was watching TV at that time.Student2: I was doing my homework then.Then, ask the students to fill in the following chart:Student1:Student2:Student3:8:00pm8:15pm8:30pmFinally, ask the group leader to report with the help of the following words:
19、Madam, at 8:00pm, Student1 was watching TV; Student2 was doing homework; Student3 was cutting hair. No one could be the robber. (Ask them to use their real names.)在这一任务设计中，前面的party事件为活动的开展创设了真实的语言情境，在调查活动中要求学生按照活动规则开展有组织、有纪律的小组合作。学生为了完成任务，会自觉地使用到target language 并加以拓展。学生的对话和汇报都很精彩，有的同学在其中加入了相应的动作，汇报中
20、根据实际情况将内容作了调整,如：Li Ling forgot what she was doing at that time. Maybe she is the robber. 充分体现了小组合作学习的成果，培养了创造性思维。（八）课后反思本节课成功的方面：（1） 整节课在新课标理念的指引下采用了task-based language teaching、Communicative Approach的教学模式，以学生为中心，让学生真正做到“learning by doing”。（2） 课堂气氛跌宕起伏，Task1导课中的一首歌很快将学生引入到学习中，使课堂气氛活跃 起来，到后面的Task6中在画
21、外星人的背景衬托下练习 “while”的用法，和Task7 The famous detective Conan的活动中，又掀起两次高潮，整堂课的各个活动自始至终围绕着过去进行时来学习、操练和实际运用，学生在轻松、愉悦的环境中达到了学习目标，感受到了学习的乐趣。（3）重点突出，形式多样：通过singing a song, pair work, playing a game, listening, groupwork等形式，让学生充分练习运用过去进行时，从而能熟练掌握，激发兴趣。 存在不足： 在这节课中，听、说、读、写的能力训练中，学生写的能力没有得到充分的训练，课后应通过做练习题来巩固知识点，或设计相应的写作训练。
