In this step, give students a few minutes to read the passage . While they are reading, I will write some key words of the text on the blackboard. Then ask students to retell the passage according to the key words.By retelling, students can improve their ability of language organization and have an overall understanding of the article.Step 4 Group discussionIn this step, students will be divided into groups of 4 to discussion the following question: What qualities make a great person?After their discussion, invite a few groups to make a report to the class.This group discussion can practice students’ oral English and cultivate their abilities of cooperation and communication.Step 5. HomeworkLet students write a short passage to introduce a great person he or she admires.The homework can consolidate the knowledge the students have learned and cultivate their writing ability. Part 6 Blackboard Design(板书设计)That’s all my teaching procedures. Finally, I’d like to say sth about part 6 blackboard design. On the top is the title. On the left, there will be some new words and expressions. In the middle of the blackboard, I will write some useful sentence structures so that the students can know clearly what they’ve learned and then try to master the knowledge.OK. That’s all for my presentation. Thank you for your attention.
基于以上分析,为使本堂课围绕重点、突破难点,同时让学生在课堂教学中能力得到提高,我设计如下教学过程。(一)创设情景认识形变由同学们已有的形变知识入手,引入新课。教师演示:①弹簧的压缩形变;②弹簧的拉伸形变③视频播放:竹竿形变、钢丝的扭转形变。得出形变的概念及各类形变。[设计意图:我从生活情景中引入新课,是为了激发学生的好奇心,为学生学习重点和难点内容作铺垫。]设问:摩天大楼在风的吹拂下会不会摆动,发生形变吗?演示微小形变放大实验:由于这种形变不容易观察,会使学生产生疑问:到底有没有发生形变?解决的办法是微小形变的演示实验。为什么光点会往下移?让学生带着问题思考后得出结论:是由于桌面发生了形变,但是形变不明显。为后面解决压力和支持力都是弹力做好铺垫。[设计意图:使学生知道“放大”是一种科学探究的方法。]
本节课是人教社物理必修1第三章第三节的内容,编排在弹力之后。该节知识既是力学的基础,也是组成整个高中物理知识的一块“基石”,所以这节内容的教学如何引领学生自主积极地探究摩擦力产生的条件和影响因素,体验摩擦力特点规律的发生过程是本节课的重点,应高度重视本节教学过程;由于摩擦力问题的复杂性,且在具体问题中又表现出“动中有静,静中有动”,尤其静摩擦在许多情形下似乎又是“若有若无,方向不定”,因此,对于初学者也是有一定难度的。也正是由于教材内容的上述特点,本节课又易于激起学生的求知欲,易于培养学生的辩证观点,易于锤炼学生的物理素质。要充分用好该节教材内容,深入挖掘知识间的有机联系,对学生开展针对性的思维训练,进而提高学生应用物理知识解决实际问题的能力和创新思维能力。高中物理《课标》对该知识点的要求是,“通过实验认识滑动摩擦、静摩擦的规律,能用动摩擦因数计算摩擦力”。其中,对静摩擦力规律的认识应该包括最大静摩擦力。
