发散思维是不依常规,寻求变异,对给出的材料、信息从不同角度,向不同方向,用不同方法或途径进行分析和解决问题的一种思维方式.长期以来,中学数学教学以集中思维为主要思维方式,课本上的题目和材料的呈现过程大都循着一个模式,学生习惯于按照课本上写的与教师教的方式去思考问题,用符合常规的思路和方法解决问题,这对于基础知识、基本技能的掌握是必要的,但对于中学生学习数学兴趣的激发、智力能力的开发,特别是创造性思维的发展,显然是不够的.而发散思维却正好反映了创造性思维“尽快联想,尽多作出假设和提出多种解决问题方案”的特
Divergent thinking is unconventional, seeking variation, the given materials, information from different angles, in different directions, using different methods or ways to analyze and solve the problem of a way of thinking.For a long time, high school mathematics teaching to focus on thinking The main way of thinking, the textbook on the subject and material presentation process follows a model, students are accustomed to in accordance with the textbook written with the teacher to teach the way to think about the problem, with conventional ideas and methods to solve the problem, which for the basics , Mastery of basic skills is necessary, but it is obviously not enough for secondary school students to learn the motivation of mathematics development, the development of intellectual ability, especially the development of creative thinking, while the divergent thinking just reflects the creative thinking Make more assumptions and propose a variety of solutions to the problem.
