教学反思：
1、本课中我通过设计不同的学习任务和活动，让学生通过独立思考和小组探究等方式顺利地完成了本节课预设的教学目标。
2、本课学习任务和活动形式多样，听、说、读、写有机有效地相结合，既丰富了课堂内容，又充分地调动了学生的积极性。
3、本课对于教材的处理（删除、修补、替换、添加）很好地体现了“用教材教”而不是一味地“教教材”。
4、小组竞赛这一课堂组织形式贯穿始终，既有组内合作，又有组间竞争，增加学生的小组合作意识、竞争意识和分享意识。
5、最后的小组活动很好地对教材进行了延伸拓展，学生的情感态度和价值观在最后一个环节中，得以升华和自我诠释，复合新课标的要求。
6、不足之处：这节课在时间的把握上出现误差，延误了2分钟；海报作品虽得到展示，但未充分地对其内容进行全面评析，未能对学生的亮点和不足进行解说。这是我在今后教学中应当注意的。
