根据G·波利亚解题表的解题步骤可知:理解问题是解题思维活动的开始,转换问题是解题思维活动的核心,是探索解题思维方向和途径的过程,是思维策略选择与调整的过程.思维方向的形成取决于很多因素,因此有必要梳理一下从哪些方面来形成思维方向.一、通过回顾反思课本知识的演绎过程形成思维方向课本中的典型定理、公式、例习题的演绎过程或思维模式往往可以成为解决问题的范式,在解题时,
According to the problem-solving steps of G. Polya’s problem-solving table, it is known that the problem of understanding is the beginning of the problem-solving activity, the transformation problem is the core of the problem-solving activity, the process of exploring the direction and way of solving the problem, and the choice of thinking strategy. And the process of adjustment. The formation of the direction of thinking depends on many factors, so it is necessary to sort out in what ways to form the direction of thinking. First, form the thinking direction by reviewing the process of deciphering textbook knowledge. Typical theorems, formulas, and examples in textbooks The deductive process or thinking mode can often be a paradigm for solving problems. When solving problems,
