新课程标准实施以来,拓展延伸成了目前教法中很重要的一个环节,在各种大型优质课比赛中、观摩课、示范课上,都成为评价一节成功课例的不可或缺的条件。拓展延伸的教学理念已经深入人心,教师在备课的时候往往花大力气设计拓展延伸的命题方式,然而由于自主支配的时间少、手头资料的缺乏、条件的限制等因素,学生对于老师的这种“良苦用心”并不全部领情。因此,笔者认为在目前的教学氛围中,应该更加关注的是如何利用教本资源搞好课内的拓展延伸。本文中,笔者结合自己的教学经验浅谈了几点设想,以期抛砖引玉。 Since the implementation of the new curriculum standards, extending the extension has become an important part of the current teaching method, in various large-scale high-quality competitions, observation class, demonstration class, have become an indispensable condition to evaluate a successful case . Extending the extension of teaching philosophy has been popular among teachers in the preparation of the time often spent great efforts to design and develop an extension of the proposition way, but due to less autonomy of the time, the lack of information on hand, conditions and other factors, the teacher for this “Good intentions ” does not all receive affection. Therefore, I believe that in the current teaching atmosphere, we should pay more attention to how to make use of the textbook resources to improve the extension of the class. In this article, I combine my teaching experience to talk about a few ideas, with a view to start a discussion.
