23、化的，以及在引力变化的情况下人体的重量是如何随之改变的。故事生动有趣、引人入胜，容易激发学生的阅读热情。一准备阶段经过内容的分析和研究，发现这篇课文内容上还是比较简单的，学生应该比较容易理解，但对于引力体重和态度的变化掌握起来有点困难，所以在教学设计上特意运用了表格的形式来帮助学生理解在不同的情况下的变化。那么整堂课的主线应该就显得比较明确了。当然在备课过程中，对于课文的导入却不知道该如何着手，不知道应该怎么样才能与课文链接起来，很顺利得让学生能够对这篇课文感兴趣。于是进过一番资料的搜索，发现了一个有关于春晖中学太空授课的视频， 那么就可以很好地和课文进行一个衔接，我想通过视频效果应该会不错，
24、既可以激发学生的学习兴趣，又可以为接下去的阅读做好铺垫。导入是想好了，但是还有一个输出问题，想了很久也没想出好的点子来，最后还是决定跟着课本走，引用课文中的讨论作为整节课的输出环节。二教学反馈优点：整一堂课，总体来说还是比较顺利的，使我印象最深刻的还是学生的表现让我感到欣慰，平常的他们总是默默的坐在座位上，即使心里知道答案也不乐意站起来回答，但是今天，不管是成绩好的还是差的都能够踊跃站起来回答问题，甚至出现争先恐后的状态，所以整堂课课堂气氛活跃，师生交流融洽，体现了以学生为主体。所以教师平常也应该多鼓励学生能够积极发言，能够和老师有比较多的交流，提高学习效率。当然整堂课下来，不管是从导入还是中
25、间部分的阅读还是比较流畅的，阅读部分的几张表格也能够很好的斜街，进过几位老师的点评也发现了自己课堂上的亮点，其中就包括了导入部分，还有就是在阅读的过程中不断渗透着阅读的技巧，帮助学生能够通过找关键句来归纳出相关的答案来。在阅读完毕之后，还通过语篇填空的形式帮助学生很好的复习和巩固这篇文章，一方面练习了高考新题型，另一方面也帮助了学生更好地理解整篇文章。不足：经过几位老师的点评，也发现了其中的不足之处。比如：1.用视频导入是不错，但是没能很好地利用视频，视频里的材料没有很好的显现出来，尤其是和阅读的三张表格脱节，如果能够更好的处理视频，挖掘里面的材料，设置相关的问题，效果会更好。2.在处理阅读部分时，由于文本内容不难，留给学生阅读的时间过多，导致最后的输出未能及时呈现，分析的时间过于长。3. 上课过程中语速还是过快，当然有一部分的原因是由于紧张，但平常的状态体现在了公开课上，所以在常态课上就应该放慢语速，尽量让学生能够很好的理解和适应。
