教学资源是为有效开展教学活动所利用的各种条件,包括教材、教案图片、课件等。教材是实现课程目标,实施教学的重要资源,但更多的教学资源则是在教学过程中产生的。这其中,学生在学习过程中所出现的错误,就是一种重要的教学资源,也是优质的教学资源,如果能够合理利用,对于提高教学有效性是大有益处的。在数学教学过程中,学生的错误难以避免,一方面我们当然要力争让学生少犯错;而另一方面,我们要充分利用这些错误来为我们的教学服务,通过它来有效提高学生的数学素养,从而提高教学质量。
Teaching resources are all kinds of conditions that are used to effectively carry out teaching activities, including teaching materials, teaching plans, courseware and so on. Teaching material is to achieve the curriculum objectives, the implementation of teaching an important resource, but more teaching resources are generated in the teaching process. Among them, the mistakes made by students in the process of learning are an important teaching resource and also a good teaching resource. If they can be rationally used, it is of great benefit to improve the effectiveness of teaching. In the process of mathematics teaching, students ’mistakes can not be avoided. On the one hand, of course, we must strive to make students make fewer mistakes. On the other hand, we must make full use of these mistakes to serve our teaching and improve students’ mathematical literacy , Thus improving the quality of teaching.
