重庆市高中生物新课改已实施三年,这三年里,在实际的教学实践中很多教师习惯性地认为,一节课40~45分钟,让学生去开展科学探究活动,耗时较多,会严重耽误教学进度。于是,有相当一部分教师在平时的课堂中把一些本应交给学生探究、思考或讨论的时间“剥夺”过来,全部包揽到自己的身上,这显然违背了课改的初衷。结合这三年高中的教学实践,浅谈如何倡导学生在探究性学习的同时,又能解决高中生物课时少和探究耗时多之间的矛盾。
In recent three years, many teachers in the actual teaching practice habitually think that a class takes about 40 to 45 minutes to allow students to carry out scientific inquiry activities, which takes more time , Will seriously delay teaching progress. As a result, a considerable number of teachers in the usual classroom to some time should be given to students to explore, think or discussion of “deprivation” over, all swept to their own body, which is clearly contrary to the original intention of the curriculum reform. Combined with the three years of high school teaching practice, talk about how to advocate students inquired learning at the same time, but also to solve the high school biology class less and explore the contradiction between the time-consuming.
