【课堂反思】九年级Unit12 Life is full of the unexpected SectionA 1a-2d21世纪教育网版权所有
本节英语课中，我让学生做到了听说、读、写练习，通过实际生活场景的回顾，引发学生思考，激发学生学习英语兴趣。21cnjy.com
小组活动，指导学生全面参与。听、练、参与课堂活动。学生相互合作，借助多媒体，提供生动直观的学习内容，学生对过去完成时的理解比较直接。针对学生综合语言运用能力不够好的情况。学生听、说、读、写的课内训练时间是必须的，多给时间是学生学习知识的保证，本节课学生在感知教材，思考事件，参与讨论应用了大量的时间。整个过程层层递进，逐步铺垫，学生一路走来非常顺畅，学习效果很好。
在语法教学方面，学生参与体验，以实践为主，采用了观察——发现——讨论——归纳——巩固——运用的语法教学模式，使学生能够更好的掌握并灵活运用本课的过去完成时。21教育网
