问题表征是解决认知活动中的一个中心环节,它说明问题在头脑里是如何呈现、如何表现出来.同样的问题,在不同人的头脑里呈现、表现的结果是不一样的,即问题的表征与人的知识结构和认知经验是有关系的.正确的表征是解决问题的必要条件,错误的或不正确的表征就不可能求得问题的正确答案.问题表征能力和问题表征的质量是影响数学问题解决的重要因素.在学习中,
Question characterization is a central part of solving cognitive activity, which shows how the problem appears in the mind and how it behaves. The same problem, presented in the minds of different people, shows different results, that is, the problem Characterization is related to the knowledge structure and cognitive experience of human beings.The correct characterization is the necessary condition to solve the problem, and the correct answer to the question can not be obtained by the wrong or incorrect characterization.Quality of characterization and problem characterization Is an important factor affecting the mathematical problem solving.In the study,
