在初中数学教学中,有许多问题需要通过变式才能进行求解。对数学问题进行合理的改变,对于培养学生数学思维的灵活性是有很大帮助的。变式应当遵守问题的本质。首先,教师应当引导学生去分析问题的本质,抓住问题的核心进行变式。这样,学生就能从多方面对问题进行分析,从而提升学生的思维层次。因此,我们在课堂教学中积极引导学生进行变式。通过课堂实践来提升学生的变式水平,在变式过程中让学生学会从多角度进行问题分析,从而培养学生的应变能
In junior high school mathematics teaching, there are many problems need to be solved through the variant. Reasonable changes in mathematical problems are of great help in developing students’ flexibility in mathematical thinking. Variants should abide by the essence of the problem. First of all, teachers should guide students to analyze the nature of the problem and grasp the core of the problem to make the difference. In this way, students can analyze the problem from many aspects, so as to enhance students’ thinking level. Therefore, we actively guide students in the classroom teaching variants. Through the practice of the class to enhance the level of students ’variant, in the process of variation allows students to learn from a multi-angle analysis of the problem, so as to develop students’
