Teaching plan Topic: S1B U4 More reading: The Mystery of Hibernation (Oxford English Senior1B) Teaching aim: After class, students are expected to 1. learn to make a guess of new words related to hibernation from the context, such as hibernation, absence, occur, pulse rate, breathing rate, den, stir, etc.; 2. learn about the background knowledge related to hibernating animals, like mammals, amphibians, reptiles, warm-blooded/cold-blooded animals, etc.; 3. learn to scan the article for detailed and useful information; 4. learn to draw conclusions based on their background knowledge and the information they’ve got from the article; 5. become interested in animal hibernation and engage themselves in the subject about how humans can learn from animal hibernation. Teaching difficulties: 1. scan the article for detailed and useful information; 2. draw conclusion based on their background knowledge and the article. stage Teacher’s activity Students’ activity Purpose Pre-reading Ask students to do a quiz. (PPT shows 6 pictures and ask students “Are they insects? Mammals? Reptiles? Amphibians?”) Ask students to classify the animals Look at the pictures and try to answer questions. --to arouse students interest and lead in. - in the pictures according to the definition. Mammals: • Definition: a group of animals that give birth to babies rather than laying eggs, and feed their young with milk. Amphibians: • Definition: a group of animals that can live both on land and in water. Reptiles: • Definition: a group of animals which lay eggs and have skins covered with small, hard plates called scales. Warm-blooded and cold-blooded animals: • The body temperatures of warm-blooded animals do not change much, while the body temperatures of cold-blooded animals change much according to the air temperatures around. The six animals share one thing in common, that is, they are all hibernating animals. Try to understand the definitions and classify the animals. --to provide students with background knowledge about the kinds of animals that hibernate. While-reading 1. Read the title of the article and raise questions about the article, such as “What is hibernation?” “When?” Try to ask and answer questions from the title and --to encourage Ss to ask questions before reading “How?” “Why?” “Who?” “Where?” . Encourage Ss to think out possible answers based on their background knowledge. 2. Ask Ss to read the 1st paragraph, and find out answers to the question raised before. What is hibernation? (Hibernation is compared to sleep.) When does hibernation occur? (It usually occurs in winter.) How do creatures hibernate? (They hibernate without moving for a long time.) Why do they hibernate? (To survive cold weather and absence of food. Or To survive coldness and little food.) As for the questions “Who hibernate? Where to hibernate? How to hibernate?”, Ss can explore the rest of the passages to find out more detailed answer. 3. Ask Ss to read para2 about hibernating bats, and find out where bats hibernate, and why. (They hibernate in a safe place in a cave. the article. Read para1, find out useful information and answer the questions by using least words. Read the passage, think and reason based on knowledge. and learn to reason based on their knowledge. --to get Ss interested in the topic and exploring the article for an answer. --to encourage Ss to scan and reason. The reason why the hibernating place should be safe is that when hibernating, bats might be attacked by predators. The predators are animals like snakes.) Ask Ss to read para3 about hibernating frogs, and find out where frogs hibernate, and why. (They hibernate deep down at the bottom of the pond. The reason why the place should be deep and warm is that in that way they can protect themselves from coldness.) Ask Ss to read para4 about hibernating bears, and find out where bears hibernate, and why. (They hibernate in the dens with leaved comfortably covered.) Ask Ss to find out something in common in the hibernating places the three creatures choose. And make conclusion about the ideal place for hibernating. (To protect themselves from predators, the hibernating place should be safe. To protect themselves from coldness, the place should be warm. So an ideal place for hibernating should be both safe and warm. ) 4. Ask Ss to scan the article from paragraph from paragraph, and find Listen carefully and think. --to help Ss better understand the way creatures hibernate. out how different creatures hibernate. Bats: -- hang upside down, looking like they are dead. --their pulse and breathing rate slow down. --their body temperatures drop as well Explain: by showing pictures on the PPT, explain the great changes in bats’ body temperatures. Frogs: --they breathe through their skin, not their mouth. (--Some frogs are even frozen, appearing dead. --they stop breathing and their heart stop beating.) Bears: --Quite different from other creatures, they do not appear dead, but look very sleepy. --When they are disturbed, they can wake up quickly. 5. Ask Ss to add subtitles to each paragraph, following the pattern “_______ bats”, “________ frogs”, Read supplementary material and know more about the way frogs hibernate. Read and answer questions. Think and answer. --to get Ss to know more about the way frogs hibernate. --to get Ss to know the details of hibernating bears. --help Ss to catch the key points in each paragraph and summarize the paragraph in their way. “_____ bears”. Show examples, like dead bats, frozen frogs, sleepy bears, etc. 6. Explain that many creatures experience hibernation every year, but no human has ever experienced it. But actually humans are good learners who have learnt a lot from nature. Show examples: Humans learn to : --make planes from birds; --invent swimwear from sharks; --invent radar from bats; What can humans learn from animals’ hibernation? Ask Ss to think of CRAZY answers. Look, think and say. --to get Ss to learn to understand the relationship between humans and nature, and what nature has inspired humans. Assignment 1. Retell the article; 2. Read articles about human hibernation in the newspaper; 3. Search the Internet for more information about one more hibernating creature. 教学反思 本人在设计这堂课时主要的思路为①引导学生从结构上理解文章,②在读文章前对背 景知识有所了解,③对文章中的抽象概念,抽象概括有具体清晰的认识,④在理解原文的 基础上能适当拓展阅读材料。本次公开课基本上将以上几个思路进行授课。以下就本次公 开课的优点和不足及改进进行阐述。 就本堂课的优点而言。首先,课堂较为流畅。导入使用 Quiz 的形式既是对之前所学 课文的联系,也是对新课的一个铺垫;除此之外,通过提问题等方式自然衔接到下一个环 节。其次,课堂较能引起学生对本话题的兴趣。对于文章中出现的抽象概念,概括等知识, 能通过图片和举具体的例子的形式进行讲解,能够引起学生对课文话题的兴趣,通水也让 学生对课文知识有更深的理解;再次,对文章的理解有宏观把握,也有细节处理,学生能 形成基本概念,也能有细节方面的理解。 就本堂课的不足和改进方面而言,首先,学生对课文做略读和细读的时间较少,尤其 在做拓展阅读上的时间尤其少,导致基础较差的学生产出较不理想;其次,课文主体部分 的处理主要通过寻找线索,通过例子和图片进行解释的方式进行,主要是教师授课、学生 吸收理解的单一形式,可多采用学生合作的形式进行;再次,课文在处理时尝试与导入联 系,但还可加强这种联系,如通过让学生回顾导入,导入的内容如异温动物/恒温动物, 哺乳动物/爬行动物/两栖动物,和课文所举的三个例子联系;最后,对拓展材料的利用率 不高,事实上所寻找的材料和课文关系紧密,可以多加以利用,如通过问题的提问,讨论 等方式进行理解。除此之外,拓展材料中也有段落是对文章和整节课的一个汇总,因而应 给与学生更多时间阅读和巩固总结。 查看更多
