Teaching reflection 本话题是 Go for it !九年级第十三单元 Section A 的阅读部分，文章的标题是 Save the Sharks! 此阅读是一篇倡议书，其中介绍了人类捕捉鲨鱼获取鱼翅，破坏生态平衡的情况，呼吁人 们保护鲨鱼，文章内容紧扣单元话题，渗透了对学生的情感教育，提高了青少年的环保意识，社会 责任感意识。 基于本节阅读材料的分析，设计意图旨在培养学生的阅读能力，

34、尤其是细节阅读能力，同时加 强学生的德育教育。在实际的操作方面，我分三阶段，第一阶段 Pre-reading， 我通过自由交谈动 物导入话题。通过视频让学生了解鲨鱼的状况，在教师描述与视频推进中，自然呈现生词，并通过 图片场景处理生词，这为读中学习做先导。第二阶段即 While-reading, 我采取了“先总后分 再总”的教学方法。即根据图片和文章标题来快速判断文章的主旨。再分段进行任务型阅读， 每一段落我设置了不同的题型，如判断正误；主题句选择；细节填空以及回答问题等。特别针对第 二段落，我还进行了思维导图的设置，帮助学生理解细节，同时也为了帮助学生用阅读过的信息进 一步理解和复述段落内容

35、。在每一任务的设置上，我都先给学生阅读策略上的指导，帮助学生快速 地找到答案，培养他们阅读技巧。第三阶段是 Post-reading，我教学的设计重在首尾呼应，为了对 整篇文章的巩固，我对文章进行缩写并挖空，并要求学生口头练习。最后，通过看视频，渗透了情 感教育，呼吁学生保护动物，保护地球。 在整个的教学方法上，我重点采取了任务型教学，由浅入深，层层推进，环环相扣的方法。也 采用小组合作的形式。课堂上小组共同阅读，合作学习，使学生在平等、协作、交流、讨论中，都 有发言的机会、表现的机会、成功的机会。阅读活动中，小组内先读，先练说，每个学生都参与了 活动。在学习活动中互相帮助，共同提高，知识和情感都得到发展，对提高阅读和交际能力起着积 极的推动作用。从教学的实践中，学生的学习氛围浓厚，每一环节都能明白老师的意图，完成了本 节课的教学目标， 但由于我刚开课时比较紧张，还有自身教学水平有限等原因，课上还有许多需要 改进的地方，但同时这节课让我更深刻的认识到，课前一定要精心准备，认真解读教材，分析学情， 精心设计，同时更应该加强学习，提炼自己的语言，提高自身的专业素质，更新教育观念和提高教 学技能，这样才能真正上好一节课。
