新目标英语九年级第七单元教学反思 一、教材分析 新目标英语九年级Unit7 Where would you like to visit? 本课的中心话题是旅游。通过认识我们四周的旅游胜地来开拓眼界，富厚自己的阅历，使自己养成勤于思考，善于总结的好习惯。 整个内容都是围绕Vacations，以生动、活泼的对话及个人的自我介绍展开的。而且这些旅游胜地都与我们的生活密切相关，通过学习，要求学生能够评论辩论自己想去的地方，并学会介绍旅游景点，同时了解世界各地的一些名胜古迹，从而能自觉地保护地球，保护环境。根据新目标对学生交际能力的培养，对学生对话及阅读能力的要求将不断提高。 二、教学反思： 1、《英语课程标准》要求以素质教育和学生的发展为根本宗旨，以培养学生的综合语言运用能力为目标。它建议教师在课堂教学中采用“任务型”学习方式，使学生带着明确的任务目标，积极主动地进行学习。在执行任务的过程中，学生通过实践、思考、调查、讨论、交流和合作等方式学习和使用英语，完成学习任务。 2、学生对所布置的任务能积极主动地完成，特别在小组任务中，组员间的团结协作能力也发挥得非常好。 3、从学生完成课后任务的反馈情况来看，学生的描述词汇数量有限，由此教师在教学中应加大词汇量，并教会学生学习整理词汇。 4、利用多媒体辅助教学，可以吸引学生的眼球，但有些学生只顾看而忘记做笔记，花费的时间比较多。所以以后视频剪辑方面可以再出色点，内容可以再紧凑些，占用的时间可以节约些。 总之，在教学过程中需要教师适时适当的引导，通过有效地设计来引导学生，使他们始终处于主动寻求知识的渴望。充分让学生发挥其主体地位，使其真正成为课堂的主人。
