So far 四、教学反思阅读课是学生比较容易接受的一种课程类型，九册书中阅读文章篇幅较长，知识点较多，所以让学生最大限度内掌握到知识点的同时，我更注重培养他们阅读
12、文章，分析文章，赏析文章的能力，通过这堂课的学习，有几点是我觉得比较好的地方：1：鲨鱼鳍视频引起了学生对于海洋环境保护的极大兴趣，且热烈的进行了小组讨论，增加了对文章阅读的兴趣2：以学生讲授为主，老师进行适当的补充，课堂效率较高3：将个人抢答问题和小组之间的竞赛灵活转换，提高了学生学习兴趣，并及时进行了奖励，增加了对学生的正强化4：课堂留给学生思考和谈论的时间，及时进行查漏补缺和回头看，加深对知识点的掌握5：以广告结尾，提高了文章学习的主题，完成了对学生情感态度价值观的升华。还有几点不足的地方：1：文章采用传统的逐字逐句翻译的形式，显得枯燥机械，应该以问题去带动学生对文章的理解，而不是单纯的只知道每个句子的中文意思2：课堂没有预留出足够的习题演练时间，不能明确的掌握学生对于重难点的掌握3：引导的范围有些狭隘，许多学生在最后表达自己的观点时，仅表达出了对于海洋生态环境的保护措施，却没有延伸到其余环境保护方面
