的实质一般说来,创造性地解决问题的过程,由发现问题,明确问题,提出假设、验证假设这四个环节组成。其中,提出假设——验证假设的环节构成了解决问题过程中的探索活动,是解决问题过程的主体。例1 学生在阅读立体几何课本《异面直线的距离》时会提出如下问题,从而展开数学思维的微观 In essence, the creative process of solving a problem consists of discovering problems, clarifying problems, making assumptions and verifying assumptions. Among them, the hypothesis - the part of the verification hypothesis constitutes the exploration activity in the process of solving the problem, which is the main body of the problem solving process. Example 1 Students read the following questions when they read the “distance between different surfaces and lines” of stereoscopic geometry, so as to expand the micro-level of mathematical thinking
