在数学课堂教学中,师生始终是围绕着课题(大问题)来进行一系列小问题的研究和探讨,一步步完成教学任务,达到教学目的,其基本流程如下:问题的提出→问题的探讨→问题的解决→结论的应用及发展其中问题的提出是第一步,也是十分重要的一步,正如陶行知所说:“发明千千万,起点在一问”。这就需要教师精心地设计每一个问题。一、设计的问题要帮助学生主动参与学习。为了发展学生的创造能力,教师应努力创设情境设计问题,让学生自己来发现问题,从而,在学习中学会用数学的思维方式去观察、分析、研究,并解决日常生活中的问题,进而形成勇于探索,勇于创新的科学精神。二、设计问题要充分运用旧知
In mathematics classroom teaching, teachers and students always carry out a series of research and discussion on a series of small problems around the subject (big problem), and complete the teaching task step by step to achieve the teaching goal. The basic process is as follows: the question is put forward → the question is discussed The solution of the problem → the application and development of the conclusion The question put forward is the first step and a very important step. Just as Tao Xingzhi said: “We invented the world with tens of millions and started from a question.” This requires teachers to carefully design every problem. First, the design of the problem to help students take the initiative to participate in learning. In order to develop students' creative abilities, teachers should strive to create situation design problems so that students can find problems by themselves. Thus, in learning, they learn to use mathematical thinking to observe, analyze, study and solve problems in daily life, and then form Daring to explore, brave in the scientific spirit of innovation. Second, the design problem to make full use of the old knowledge
