学生通过听课,学到了数学知识,还必须运用这些知识.独立完成作业,才能消化和巩固所学知识,并获得相应的数学能力。数学教学中让学生进行练习、解答习题,既是使学生真正掌握知识和能力的一种手段,也是为他们今后实际应用这些知识和能力的一种准备。对学生的作业,最基本的要求是必须做到正确无误,这是保证教学质量的一项必要条件。因此,认真负责的教师,对学生的作业,都要采取积极措施,使错误不断减少以至完全消灭。学生作业中发生错误的原因,是参种多样的。从时间远近来说,有的是由于最近几堂课没有学好,有的则是由于以前的基础没有打好。从表现程度上来说,有的属于完全不懂;有的是懂得不透彻;还有的 Students through lectures, mathematics knowledge, but also must use these knowledge.Operating homework independently, in order to digest and consolidate the knowledge, and access to the corresponding mathematical ability. Letting students practice and answer exercises in mathematics teaching is not only a means to enable students to truly acquire knowledge and abilities, but also a preparation for them to actually apply such knowledge and abilities in the future. The most basic requirement for students’ homework is to be correct, which is a necessary condition to ensure the quality of teaching. Therefore, teachers who are responsible and responsible should take positive measures to students’ work so that the mistakes will be reduced and eliminated altogether.
