人教版高中生物必修2染色体变异说课稿
四、说教学程序（一）.温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变，从而使遗传信息改变，使蛋白质结构改变、生物性状改变，即生物发生了变异。那么，基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断，染色体是DNA的载体，基因在染色体上呈线形排列。引出新知:对于一个生物体来说，正常情况下，其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下，染色体的结构和数量均会发生改变，从而导致生物性状的改变，这就属于染色体变异。（二）.把握重点、突破难点重点的把握：1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高，很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下，存在着严重的智力障碍。阐述病因---染色体片段缺失
人教版高中政治必修1价格变动的影响说课稿
回归生活：近几年,我国市场上猪肉价格在不断地波动。请智囊团商议：我们集团如何才能避免重蹈“张老汉”的覆辙？学生活动：思考、发言、群策群力。教师鼓励学生从多角度分析，找出解决问题的不同方法。教师点拨：在猪肉价格波动较大时，我们除了调节生产规模，还可以采用引进新品种、加强科学管理等手段来提高劳动生产率，从而在价格竞争中更具优势。同时，我们要在激烈的市场竞争中站稳脚跟，还必须以市场为导向，生产适销对路的高质量产品，做到“人无我有，人有我优，人优我转”。教师引导学生分析：价格变动对生产规模的调节、对劳动生产率的提高及促使企业生产适销对路的高质量产品，就是在价格、供求关系及市场竞争的刺激下，价值规律发挥“棒子”（调节资源配置）、“鞭子”（鞭策个别劳动生产率的提高）及“筛子”（优胜劣汰）作用的结果，从而将本节课的内容与第一框题有机联系在一起，帮助学生从不同角度更深刻的理解价值规律的作用。

Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times.

Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
