unit9 when was it invented?第三节 （period 3）本节与上节相关性分析：本节课在上节课介绍各种发明物的基础上更进一步地探讨一些有关吃的东西的味道以及它们的发明史。教材提到“薯片”的发明历史，这是小孩子特别爱吃的食物，所以学生比较感兴趣。本节课是上节课的一个延伸和拓展。通过听力和口语训练，让学生自己讲述“薯片”的发明历史。最后以谈论“飞碟”的发明史从而更进一步地提高了学生会话的能力。课型：listening& speaking 时间：45 minutes教材内容：section b 1a,1b, 2a, 2b,2c,3b教学要求：1. language goals: i. words & expressions crispy, sour, sweet, bitter, hot, salty, by mistake, in the end, sprinkle ii. key sentences it was invented by mistake.2. ability goals：enable the students to use the passive voice. 3. emotion & attitude goals：enable the students to be aware of different inventions around them.4. strategy goals： enable the students to use what they know to explain new words.教学重点:understand and use the new words, phrases and the passive voice correctly.教学难点:introduce the history of potato chips according to the listening materials.教学方法: instigative method and instigative method教学手段: a computer, blackboard, the listening materials, pptteaching procedures （教学步骤）stepsaimsteachers activitiesstudents activitiesteaching methodsstep ibrainstormrevisionto help the students to revise the words about some food.show some pictures about different kinds of food that students have learned before.(divide the whole class into four groups)say out the names of some food. instigativemethodstep iipairwork 1. to get the students to talk about the tastes of different food.2. to get the students to know the expressions of the tastes.give the students an example: a: how the potato chips taste? b: it tastes very tasty.then ask them to work in pairs and learn the words: crispy, sour, sweet, bitter, hot, salty, work in pairs.elicitationmethod slide 3,4,5,6,7&8step iii:free talkto lead in the target language.ask the students some questions about potato chips.talk with each other.elicitationmethod zstep iv:listening practiceto practice the students listening skills.ask “how were the potato chips invented?” read the instructions to the class. play the recording. check the answers. students listen and finish 2a &2b.elicitationmethod sep v: speaking practiceto practice the students speaking skills.ask the students to role play the conversation about the invention of potato chips.work in pairselicitationmethod step vi:extra speaking practiceto practice the students speaking skills.lead the students to make conversation about the invention of flying disk.work in groups according to the listening materials.inductive methodstep vii exerciseto help the students to practice what they learned today.show the students to exercise.finish the exercise.inductive and elicitation methodstep viiihomework1.retell the history of potato chips2. write an article about the invention of the flying disk. 附一：(blackboard design) g1 g2 g3the emperor-was boiling-over 正 正 正some leaves-fell into-remained 正 正 一the emperor noticed-produced 一 教学反思：本节课是听说课。主要是依靠口头训练，检验与促进语言的吸收与听力能力。听力材料内容是有关学生比较感兴趣的话题：薯片的发明史。大家都知道听说课就是一个对语言的感知、解析、和应用的过程。我记得美国认识心理学家安德森（anderson）曾认为：听力理解过程可划分为三个阶段，即感知过程(perceptual processing)、解析过程(parsing)和应用过程(utilization)。这三个过程相互交迭、循环往复、不断修正。所以本节课在听力之前我先让学生进行一个“free talk”，让学生自由发挥谈论有关potato chips的内容。这看似是一个口语活动，与听力无关，其实不然。它是听力训练中的一个重要环节。这个free talk就是语言的感知过程。然后引出本节课的语言目标when was it invented?让学生带着问题去听，其实这是一个对语言目标的解析过程。最后再利用对话的形式(work in pairs)对potato chips的发明史进行对话，这是对目标语言的应用。在应用过程中，输入到学生大脑中的话语意义和学生的现有知识相互联系起来，于是学生就对整个口头语篇产生丰富的先前知识，并能把先前的知识更好地组织起来，加以更策略地运用。应用过程既是对听力理解力的检测，又是对听力理解力的促进，为听力能力的进一步发展
