八年级英语下册 How long have you been collecting shells教案 人教新目标版

《How long have you been collecting shells?》教学实录 时间：Apr.11 地点：北海中学 授课、实录整理、反思：苏海玲 教学内容：八下unit6 课时：1a---2c 教学目标：Talk about how long people have been doing sth 【抽到题目，感到有点难度，不是因为对教材的陌生，而是因为这是一节新授课，学生不仅要学习新单词，而且还要接触新的语法：现在完成进行时，课的任务是1a到2c,任务量也非常的大，我预测到学生学起来会吃力，基于此，我对教材内容进行了一点微小的变化，把和本节内容毫不相干的标题换成了和所授内容息息相关的“How long have you been skating?” 相对来说我觉得更容易把学生引入到话题中来。】 课堂实录及反思： T: Hello, everyone! Nice to meet you! I’m very happy to be here as your new English teacher, so I’m happy and I have a gift to you. Gift, do you know?【用礼物来引出歌曲，刺激学生的好奇心，吸引学生的注意力和兴趣】 Ss: Yes. T: OK. Do you like listening to music? Ss: Yes. Very much. T: Good, my gift is an English song. Now please listen carefully and then join me in singing, OK? Ss: OK. T: Sing, sing , sing a song, come and sing along, Jolly Jolly Jolly Jolly, life is like a song. Ss: Listen and then join Miss Su in singing. T: Good. You did a good job. Are you happy？ Ss: Yes. 【教唱英文歌曲，激发学生兴趣，同时为新课导入做好铺垫。】 反思： 学唱英文歌曲及教唱英文歌曲一直是我的心愿，我希望我的学生 在英语学习中不仅仅学到知识，还要得到乐趣，在他们学唱的过程中 我发现他们眼中的惊喜和兴奋，这就够了。 T: Look, I like singsing, I started singsing in 1980, Now it’s 2011, so I have been singsing for 31 years. (draw a time line) Today we will talk about how long you have been doing sth. (write it on the blackboard) Please tell me “How long have I been singing?”【在时间线上标出关键的时间点，时间段，让学生清晰的看出时态的意义。】 Ss：（help them to answer）You have been singing for 31 years. T: Read after me: I have been singing for 31 years. Ss: I have been singing for 31 years. (read it for three times) T: I was born in 1976. In 1980, I was 4 years old. So I can also say: I have been singing since I was four years old. (write it on the Bb) How long have I been singing? Ss: You have been singing for 31years. (help them to answer) You have been singing since you were 4 years old. Then read them twice.【这里教授新词since, 学生发音不是很好，教读了五遍。】 T: We can also say: I have been singing since 1980. 【领读，让学生通过看时间轴来感知。】 Ss：I have been singing for 31 years. I have been singing since I was 4 years old. I have been singing since 1980. Using the same way to teach : T: How long have I been teaching? How long has Jack Chan been teaching? S1:You have been teaching for 10 years. S2: You have been teaching since 2001. S3: You have been teaching since I was 24. S4: Jack Chan has been acting for 50 years. S5: You have been teaching since 1961. S6: You have been teaching since he was 7. T: Do you know Deng Yaping? Who is she? Ss: Yes. She is a ping-pong player. T: She started playing ping-pong in 1978, she stopped playing in 1997. Now she don’t play ping-pong. How long did she play? Ss：（help them to answer）Deng Yaping played for 19 years. T: We don’t use “she has been playing”, we use “she played”, because she don’t play now. She stopped in 1997. OK. How long did she play? Ss: She played for 19 years.【运用学生熟悉的成龙、邓亚萍让学生进行操练，加深印象，强化知识的渗透。】 T: OK. Today we will talk about how long you have been doing sth and how long you did sth. (Write them on the Bb) Clear? Ss: Yes. 反思： 在本环节中，虽然考虑了学生对名人的熟悉和迷恋引入了成龙和 邓亚萍，然而在追求真实的情况下，学生对于时间的计算和读加大了 难度，这也说明我对学情了解的不够。但是对于重点的突破做的很好， 能够让学生通过观察时间轴明白时态的真正含义，学生可以一目了然。 T: Now open your books and please turn to P44. At first, look at the picture, what are they doing? S7: They are skating ? T: What does “skating” mean? S8: “溜冰”。 T: Yes, they are skating because the they are have a skating marathon. Marathon? Do you know? Guess. Ss: “马拉松”。 T：You are so great! Marathon is a long race .【通过图片和语境,让学生感知猜测新词,锻炼学生能力和智力.】 look at the students, they have skated for some time. Now listen and write down how long they have been skating or how long they skated. For example, Please tell me: How long has Alison been skating? Ss: He has been skating for five hours. T: How long did Sam skate? Ss: He has been skating for four hours. T: No. he skated for hours. Not has been skating. Clear? Because he has stopped. Ss: Yes.【指导学生通过对图片的观察和思考，让他们明白他们可能会面临的问题，提高学生的思维。】 反思: 对于现在完成进行和一般过去时,我花费了很大的努力让学生感知,操练, 但是仍然发现部分学生有困惑,不过想在一节课让学生都掌握,这也是不现实的. 要对学生存在期盼. T: Now let’s listen. Are you ready? Ss: Yes. (listen to the tape and write down the answer) T: (听力背景声音是运动会的场景，很嘈杂，不是很清晰.) Listen again. And you can write only the hours. Ss: listen to it again. T: OK. How long has Victor been skating. S: He has been skating for five hours. T: He has been skating for five hours. Right? Ss: Yes. T: Celia. Who can tell me your answer. Any volunteer? S: She has been skating for two hours. T: En, She skated for two hours.【学生在此听力中，对现在完成进行时和一般过去式的区别存在错误，通过重复对学生的错误给与改正。】 Pay attention to: How long has Victor been skating? How long did Celia skate? OK. Now 1c. First let’s read it together. Ss: How long has Alison been skating? He has been skating for five hours. How long did Sam skate? He skated for four hours. T: What about Victor and Celia, please work in pairs, ask and answer, clear? Ss: Yes. They ask and answer together.(It lasted 2 minutes.) T: Have you finished? Celia has stopped, so we should ask “ how long did Celia skate?” Victor is still skating, so we should use “how long has Victor been skating?” OK, now let’s talk about them. Which pairs? Ss: 10 students stand up and show their dialogues. 反思: 教师要管住自己的嘴, 把课堂还给学生, 我争取让更多的学生在课堂上有更多的展示自我的空间，虽然很多学生都举首发言,但是重复率太高,我鼓励发言不积极的男生参与活动中,在后来他们的表现也让我感到很安慰. T: All the students are having the skating marathon, do you want to know who the winner is? Do you know who won the first prize? Ss: Yes. T: OK. Let’s look at the picture in 2a. Who is the girl? Ss: She is Alison.(对比1a、2a 中的图片得知)
