“解决问题的策略”与传统应用题教学不同,策略是对解决问题方法的理解与升华,树立策略意识、形成基本策略有利于将解决问题的一些具体方法上升为数学思想的感悟。在学生解决问题的过程中,要超越具体的解法,实现数学基本经验的积累与数学思想的感悟,其有效的途径就是组织学生反思、说理,促使学生解题后能沉下心来思考,并外化为数学说理表达,以说理促进内化,在内化、外化的相互作用中实现认知的升华。
“Strategy to solve problems ” Different from the traditional teaching of application problems, the strategy is to understand and sublimate the solution of the problem method, establish the strategic awareness and form the basic strategy is conducive to some specific solutions to the problem raised to the sentiment of mathematical thinking. Students in the process of solving the problem, to go beyond the specific solution to achieve the accumulation of basic mathematical experience and insights of mathematical thinking, the effective way is to organize students to reflect on the reasoning, prompting students to settle down to think down and outside Into the mathematical theory of expression, to reason to promote internalization, internalization, externalization of the interaction to achieve cognitive sublimation.
