　　优点:   
　　新课程倡导学生是学习的主体，要培养学生的自主、合作和探究学习的能力。反思自己的这堂课，我在授课的过程中定位自己的角色就是引导作用，充分发挥学生独立学习和合作探究学习的主动性。很显然，在这样的课堂中，学生有一定学习的自主性，学习兴趣比较浓厚，课堂气氛活跃、学生参与度高，从而使得课堂效率也比较高。所以在以后的教学中要继续保持，努力做到“三讲”、“三不讲”，力求做到让学生快乐、自主地学习。
　　我在课堂上弱化了自己的板书，从分利用教室的白板让学生们多动手去写，并让学生批阅，这也是一举多得的事情。既锻炼了学生，又能多发现学生的问题。
　　不足:
　　不足之一：如果学生出现的错误还能让学生自己去解决就更好了。很遗憾，
　　我代劳了。
　　不足之二：因为时间关系小组评价环节没有统一把得分当堂加起来，虽然有专门的学生负责，但如果当堂呈现会更加完美。
　　不足之三：超时。最后环节学生太high了，我也没把握好时间及时控制。
