解决问题的策略属于实践与综合应用的范畴,它是数学学习的一个重要领域,具有很强的现实性和应用性,同时极具挑战性。通过解决问题策略的教学不能仅仅满足于让学生解决某一类问题,而应让学生在解决问题的同时经历策略的形成过程,进而反思和提炼。下面以“替换”策略的教学为例,谈谈自己对学生习得和形成解决问题策略的一般过程的粗浅认识。 The strategy of solving the problem belongs to the category of practice and comprehensive application. It is an important field of mathematics learning. It has strong practicality and applicability and is very challenging. Teaching by solving problem strategies can not be satisfied with letting students solve a certain kind of problems. Instead, students should experience the process of strategy formation and then reflect and refine. Let's take the teaching of “replacement” strategy as an example to talk about my superficial understanding of the general process of student acquisition and problem-solving strategies.
