作为数学组成员,有幸观摩了教研公开课《解决问题的策略——倒过来推想》,让我对倒过来推想的策略有了更深入的了解。倒过来推想是从事情的结果倒过来想它的开始,体会反思逆推的一种策略。这样,使学生经历了一个从“策略简单”到“策略丰富”再到“策略优化”的发展过程,他们就会掌握“倒过来推想”的策略。 As a member of the mathematics group, I was fortunate to observe the open-ended lesson of teaching and research, “Strategy for Problem Solving - the other way round,” and let me have a deeper understanding of the strategy put forward in reverse. The other way around is to think of the beginning of the outcome of the work and to understand the tactics of retrospect. In this way, students are guided by a “simple strategy ” to “strategy ” “to ” strategy optimization “development process, they will grasp ” Inferiority "strategy.
