无论是正常的数学教学还是复习备考,“习题课”都处于一定的重要地位.习题课通常有两个目的:一是系统概括知识内容,沟通各类知识联系;二是提高解题能力,培养学生的数学思维品质.为了达到这两个目的,教师必须精选例题、习题,进行强化训练.这里第一个目的是具有客观性,第二个目的具有主观能动性.往往有的教师注重了第一个目的,而忽视了第二个目的.其结果,题目练的不少,解题能力仍然不能提高.究其主要原因是学生的思维品质没有得到相
No matter whether it is normal mathematics teaching or review preparation, “research class ” is in an important position. Exercise class usually has two purposes: First, the system summarizes the knowledge content, communicates all kinds of knowledge; second is to improve the ability to solve problems. To cultivate students’ quality of mathematics thinking. In order to achieve these two goals, teachers must select examples, exercises, and intensive training. The first purpose here is to have objectivity, and the second purpose is to have subjective initiative. Often, some teachers pay attention to The first goal, while ignoring the second goal, results in a lot of problems and the ability to solve problems still cannot be improved. The main reason is that students’ thinking quality has not been matched.
