《数学课程标准》把“解决问题”作为四大课程目标之一,如何让学生“形成解决问题的基本策略,体验解决问题策略的多样性,发展实践能力与创新精神”也相应成了实现这一课程目标的重要载体。所谓解决问题的策略,是指学习者在具体的情景中,通过联系已有的知识和经验,运用数学思维方法,发现问题与条件之间的关系,从而解决问题的一系列规则。解决问题的策略不是以解决问题为终极目标,而是重在策略的形成和发展,它区别于应用题和解决问题。那么如何才能使学生在解决问题的过程中形成策略?关
As one of the four major curriculum objectives, Mathematics Standards for Lessons put “solving problems ” one of the four major curriculums, and how to enable students to “form the basic strategies for problem solving and experience the diversity of strategies to solve problems, develop practical skills and innovative spirit” Has become an important carrier of the goal of this course. The so-called strategy to solve the problem refers to a series of rules that the learner solves the problem by contacting the existing knowledge and experience, using the mathematical thinking method and discovering the relationship between the problem and the condition in the concrete scenario. The solution to the problem is not to solve the problem as the ultimate goal, but to focus on the formation and development of the strategy, which is different from the application of the problem and solve the problem. So how to enable students to form a strategy in the process of solving the problem?
