PEP4 Unit4 At the farm 教学反思洪合镇中心小学 刘桂荣 一、 教学内容：第2课时A Lets learn及Lets chant 课型：词汇 二、教学目标1知识目标（1）能够听、说、认读单词tomato，potato，carrot，green beans。（3） 能理解句子Look at the green beans. Theyre so long. Yes, and the potatoes are big.（3）会说唱歌谣。2能力目标 培养学生的口头表达能力和表演能力。3情感目标 教育学生要有合理的饮食习惯。三、教学重难点教学重点：掌握三会单词tomato，potato，carrot，green beans。教学难点：掌握单词potato和tomato的复数形式。四、教学过程Step 1Warming up创设情境，导入新课。T: Today we are going to an interesting place.a) It has many trees and grass. b) It has many animals.c) It has many vegetables.d) There are potatoes, tomatoes, carrots and green beans.Can you guess? Where are we going? Ss: Farm.T: Yes, we are going to the farm.设计意图：根据心理学家提出的“U型”效应告诉我们，要把最重要的事情安排在开头和结尾的部分，由于小学生自身活泼好动的特点，本课的导入自然有趣，创设一个真实农场的情景，把四种学习的蔬菜整体呈现给学生，这时学生的记忆尤为深刻。Step 2Presentation1. Teach “carrot（s)-yummy”1) T: Lets play a guessing game: its a kind of vegetables. Its orange. The rabbits like it very much. Whats it？Ss can answer it both in Chinese and English. Then T will show the word card and the picture and drill it. T will lead activity and pick some S group to read.T: Then lets count the carrots in the picture. (e.g., One carrot, two carrots many carrots.)教师出示word card “carrots” 并张贴，教师带读，抽查2小组读。2) I like carrots. They are yummy.（出示单词卡，背面注上中文，抽读个别学生，教师带读新单词。)趣味拍手操练chant: I like carrots. I like carrots. Yummy, yummy, yummy.（师生示范chant，学生之间pair work。）设计意图：以一个谜语导入本课的新授知识，富有一定的创意，容易激发学生的好奇心，调动学生的积极性，并在自编的chant中不知不觉地学习如何描述carrot。2.Teach “Green beans-tender-long”1) T: Show a picture of “green beans” and ask “what are these? Are they carrots?Ss: No, they arent. They are green beans.（教师启发）Ss show the word card and drill it.2) T: Look at the green beans. Theyre tender. （比较几根发蔫的四季豆和新鲜的四季豆。）Then, show the word “tender” and ask Ss to read it.趣味拍手操练: I like green beans, I like green beans, tender, tender, tender. (Use the different intonations.)3) Look at the green beans. Theyre long. (Show two green beans and compare them.）Show the word card “long” and let Ss read it.3. Teach “tomato(es)-juicy”1) Show a bag. T： Look! I have a bag. There is something in it. Who wants to come to the front and taste? Be brave!2) Close your eyes. Open your mouth. Whats it?当学生得出答案时，教师出示实物及单词，逐步引出one tomato，two tomatoes，从而引出tomato的复数形式。3) Play the finger exercises. 请学生看老师的手指数量来判断应该使用tomato还是tomatoes。4) Show tomatoes.T: Look at the tomatoes. What color are they？Ss: They are red. T: Yes. Theyre red and juicy.教师用手掰开西红柿并展示词卡。Then ask the boys and girls to repeat it.趣味拍手操练:I like tomatoes, I like tomatoes, juicy, juicy, juicy.设计意图：在这个教学环节教师应用了一个不同的导入方法，让学生通过品尝从而引出tomato。应用finger游戏让学生掌握tomato的单复数关系，避免了讲语法的枯燥，符合小学生的心理特征。4. Teach “potato(es)-tasty”1) Show a bag.T: Look at the bag. Can you touch and guess “Which one is the potato?”Ss touch it and try to find out the potato.通过这个“摸一摸”游戏，引出新单词potato，然后出示单词卡，让学生认读。接着引导学生数一数共有多少个potato。2) Play a short game “High and low”.巩固操练potato的读音。3) Show the true potatoes.T: Look at the tomatoes. Theyre red. Look at the potatoes. Theyre brown.编一个chant巩固知识：带领学生分小组一起吟唱。Tomatoes, tomatoes, “t” is for tomatoes.Potatoes, potatoes, “p” is for potatoes.4) T: When the potatoes become fries, theyre tasty.趣味拍手操练：I like potatoes, I like potatoes, tasty, tasty, tasty.5) T shows two potatoes and compare them.T: Look! This potato is big.T shows the word card “big” and let Ss read it.设计意图：根据心理学的“连锁塑造效应”，我们先把教学目标分解成若干个小目标，学生每完成一个小目标我们都及时对其进行鼓励表扬，最终完成新课的学习。在这个环节里，教师让学生通过摸一摸、猜一猜的方式引出potato。并把potato 和tomato进行了比较教学，以一个chant 加深学生对这两个音、形近单词的印象，最后一个环节教师又把单词教学落实到句型中，使单词教学更具意义。Step 3Drill1. Games Teacher says the words and asks two students to point out the picture. Lets see who is quicker.（看图说单词）Guessing game: one student holds the picture, the other student guess. Use the structure:S1: what are these? S2: are they.?S1: Yes, they are. / No, they arent. Bingo Write the four words on the paper:1) For the first time: listen and tick. When you finished, put up your hands and say “bingo” lets check and see who can get the first bingo.2) For the second time: listen and circle. When you finished, put up your hands and say “bingo”. Lets check and see who can get the second bingo.3) For the third time: listen and cross. When you finished, put up your hands and say “bingo”. Lets check and see who can get the third bingo.设计意图：复习巩固所学单词，为下面的句型教学作铺垫。2. Lets learnNow, Sarah and Mike are at the farm, too. Lets listen to the tape.教师播放Lets learn的内容。 1) 第一遍，学生听录音回答问题：Are the green beans long? Are the potatoes big?2) 第二遍，订正答案并跟读。3) Pair work: one student is Sarah, the other is Mike.4）Show time.设计意图：根据是德国心理学家艾宾浩斯研究发现的人类记忆遗忘曲线原理，下课前回归文本，通过听读、演一演的活动，及时复习巩固本课学习的新知识。Step 4Consolidation这节课我们学习了tomato，potato，carrot，green beans四种蔬菜的名称，它们是农民伯伯通过辛勤的劳作才得以收成的。我们知道蔬菜含有丰富的维生素C，应该多吃蔬菜，因为它们有益于我们的健康。Lets chant:跟随音乐一起进行歌谣说唱。设计意图：课堂的最后，谨防心理学上的超限效应，通过学生喜欢的chant形式
