【教学反思】
教学也是一种艺术, 我也一直把这句话作为激励自己的座右铭。因此, 平时在上每节课时我总是希望自己能把课上得更精彩些！这次作为面向全校观摩和研讨的五生课堂, 在设计教学课件时, 我更是处处留意, 仔细考虑每一个环节的设计。
作为一节阅读课, 为了使学生们把课文读到位, 学到位, 在整体设计上，我仍不放松学生对四会技能的把握。分别从听、说、读、写四个角度来指引学生对aspirin和penicillin两种药的掌握, 课文理解形式多样。此外，在每一环节的过渡句上，我是深思又深思, 力求环环相扣, 丝丝相连, 旨在能激发学生的求知欲, 引导学生积极思考，踊跃发言。从课堂效果来看, 学生配合默契, 课堂氛围较为活跃。从而体现了生动和生本两大特色。创新设计环节, 情景剧的创作旨在要求学生根据本节课对aspirin和penicillin的掌握, 能学以致用, 会用英语讲述这两种药的效用, 给病人看病开药, 拯救生命, 创造幸福和谐的社会面貌。从而体现生活、生态、生命这三大理念。
当然, 本节课从课堂实际操作效果来看, 也存在小毛病。例如, 在视频导入penicillin这一环节中, 学生对视频内容的回答并不理想, 如若能设计一些问题, 带着问题去看视频, 那将会大大降低难度, 学生任务也更加明确。另外, 在创新设计环节, 学生并未能充分利用黑板上总结好的板书, 有两组学生的表演对药的功效并未谈及多少, 此处若是指令再清晰些, 要求再明确些, 那将使本节课更加锦上添花！这些暴露出来的问题说明在今后的学习和课堂教学中我仍有提升的空间。教无定法, 学无止境。我定会积极进取, 认真思考, 科学钻研,不断实践，使自己向更高更好的目标迈进！
