三、反思

1.本文所设计的问题实际上是英语课与生物课中的“环保”章节的整合,学生较熟悉。老师让学生列举污染源,学生讲出了很多的污染源――空气污染、水污染、土壤污染、噪音污染等。

2.老师让学生分组讨论如何解决这些污染问题,巧妙地运用合作学习法,从而不但培养了学生探究问题和自主解决问题的能力,而且培养学生参政议政的意识。学生们以主人翁的身份,提出了种种解决方法。解决水污染问题,他们先用劝说的办法,当此法行不通时,再借助新闻媒体的力量,最后上告政府;解决空气污染问题,他们号召人们骑车上班。当老师提醒他们,若家离工作地方很远,不能骑车上班时,该怎么办?他们马上想到了公交车。他们要求政府增加公交车辆,建造地铁。

3.老师因势利导,请他们回忆一下,以前有否做过有损于环保的事情。其实是英语课与政治课的整合。在这么和谐、民主、激动的气氛中,学生们毫无顾忌,畅所欲言,纷纷讲述了自己以前的不文明表现。当老师问他们以后还会做这种事吗?他们很真心地回答:“No.”自然恰当的德育渗透,起到一箭双雕的作用,使活动达到了高潮。

总之,整个过程,教师不是在“教教材”,而是在“用教材教”。教师根据学生的实际情况和生活经验创造性地使用教材,从学生熟悉的知识入手,创设一个个与学生生活密切相关的问题情境,让学生带着问题思考,寻找解决问题的办法。真正体现了《新课标》的精神:“在发展语言能力的同时,发展思维能力,激发想象力和创造力。”同时,也实现了“六环节”课堂教学中,坚持“以学定教、高效互动”的基本理念。
