在数学学习中,一题多解能启发学生的发展性思维,开拓学生的视野,激发学生的学习兴趣。但是,如果教师只是单一地罗列出多种解法,简单讲解,不进行知识的联系与归纳,那么学生除了惊叹解法的精妙之外,将一无所获。因此,在一题多解中,我们要体现出“归一”原则。所谓“归一”原则,对解题而言,就是将解题的经验进行总结归纳,提炼出一种针对某一题型行之有效的方法,也就是我们所说的
In mathematics learning, one problem and multiple solutions can inspire students’ developmental thinking, develop students’ horizons and stimulate students’ interest in learning. However, if the teacher only lists a single solution to a variety of solutions, simple explanation, without the connection and induction of knowledge, then students in addition to marveling the subtleties of solution, nothing will be gained. Therefore, in a multi-pronged solution, we must reflect the principle of “return to unity.” The so-called “return to the same ” principle, the problem-solving, the problem-solving experience is to summarize, extract a kind of effective method for a problem type, which is what we call
