人教版高中生物必修1细胞的衰老与凋亡说课稿
4、最后从生物的寿命引入，探讨细胞的死亡。强调细胞死亡有两种形式。(1).细胞坏死，它是由某些外界因素造成细胞急速死亡，是一种被动性死亡；(2).细胞凋亡，这是一种由特定基因控制的主动性死亡。细胞坏死与细胞凋亡在形态学和生物化学上有着明显的区别。细胞凋亡有广泛的生物学意义，比如胚胎发育期手的发育如果没有细胞的调亡就不会有纤细的手指；如果没有正常的细胞调亡，蝌蚪的尾部就不会消失，它将永远不能变成青蛙……。正常的细胞调亡还肩负着维持各种组织器官固有体积和形态的功能；还会使机体内异常的细胞得到及时清除，去处潜在的隐患；例如癌症就是异常的细胞没有及时死亡的结果……。因此细胞的正常死亡是生物体的一种非常重要的调节机制，是机体平衡细胞增殖，调节机体细胞树木恒定的方式，是必不可少的生命过程。（15分钟）5、课堂小结，可以把课堂传授的知识尽快地转化为学生的素质；简单扼要的课堂小结，可使学生更深刻地理解政治理论在实际生活中的应用，并且逐渐地培养学生具有良好的个性。
人教版高中生物必修2DNA的复制说课稿
设问：DNA复制后两个子代DNA分子与亲代DNA分子是否完全相同？为什么？通过设问，让学生进一步理解和巩固DNA复制的全过程。接下来让学生总结出DNA复制的四大基本条件：① 模板：开始解旋的DNA分子的两条单链；② 原料：是游离在核液中的脱氧核苷酸；③ 能量：是通过水解ATP提供；④ 酶：酶是指一个酶系统，不仅仅是指一种解旋酶。最后通过以上分析，总结出DNA复制的意义以及在生活中的应用：意义：DNA通过复制，使遗传信息从亲代传给子代，从而保证了物种的相对稳定性，保持了遗传信息的连续性，使物种得以延续。应用：目前DNA分子广泛应用于刑事案件侦破等方面：如：DNA分子是亲子鉴定的主要证据之一。把案犯在现场留下的毛发、血等进行分析作为破案的证据，与DNA有关。五、设计课堂练习：设计一题典型课堂练习：即有关半保留复制及计算的习题：

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
