《义务教育数学课程标准》在课程目标中指出:“数学教学要形成解决问题的一些基本策略,体验解决问题策略的多样性,发展实践能力与创新精神”。解决问题的策略作为数学学习的一个重要领域,具有很强的现实性和应用性。解决问题策略的学习,必须和解决问题紧密联系在一起。解决问题时,要让学生经历策略形成的过程,进行感悟、反思和提升,并运用所学策略解决新的问题。下面以“倒推”策略为例,谈谈一些笔者个人的想法。
“Compulsory education mathematics curriculum standards” in the course objectives pointed out: “Mathematics teaching to form some basic strategies to solve the problem, to experience the diversity of strategies to solve problems, develop practical ability and innovative spirit ”. Strategy to solve the problem as an important area of mathematical learning, with strong practicality and applicability. Studying problem solving strategies must be closely linked with problem solving. Solve the problem, let students experience the process of strategy formation, perception, reflection and promotion, and use the strategies learned to solve new problems. The following to “push back ” strategy, for example, to talk about some of my personal thoughts.
