数学教学的目的,是知识的传授和思维能力的培养。中等生的知识基础、智力水平等方面都具有一定的素质,他们能接受教师传授的知识,思维比较清晰、比较合理、比较准确,能够比着葫芦画出瓢。但相对优等生有一个突出的特点是学习不够稳定,思维灵活性不够,学到的数学基础知识不能灵活运用,不能举一反三、触类旁通,表现在课堂中有时对知识理解不透,思维受阻无法畅通,导致学习兴趣不强,所以教师特别要注重中等生思维能力的培养,激发中等生学习数学的内驱力,引导他们亲历知识形成的过程,摸索总结出一套适合自己的科学的学习方法。 The purpose of mathematics teaching is to impart knowledge and train thinking skills. Secondary students knowledge base, intelligence and other aspects have a certain quality, they can accept the teacher’s imparting knowledge, thinking more clearly, more reasonable, more accurate, than the gourd to draw a scoop. However, one of the outstanding characteristics of comparatively superior students is that they are not stable enough in learning, they have not enough flexibility in their thinking, they can not apply the basic knowledge of mathematics flexibly, can not give top priority to one another, bypass the classifier, sometimes fail to understand the knowledge in class, Resulting in a lack of interest in learning. Therefore, teachers should pay special attention to the cultivation of middle school students’ thinking ability, stimulate the secondary students to learn the internal driving force of mathematics, guide them through the process of knowledge formation, and find out a set of suitable scientific learning methods for themselves.
