发散思维是不局限于既定的理解,对信息进行多方向、多角度的思考,从而提出新问题,探索新知识或发现多种解答和多种结果的思维方式。它是创造性思维和灵感思维的基础。教师苦能在课堂教学中注意创设问题情境,提出激发学生发散思维的问题,引导学生从正面和反面多途径去思考,纵横联想所学知识,将对提高学生思维能力和探索能力是大有好处的。一、创设问题情境,提供发散思维时机数学知识的发散性是普遍存在的,但数学知识和数学问题所蕴含的发散总有强弱之分。在课堂教学中,要根据学生的智力发展水平,教材内容的深广度要求以及学习过程的阶段性来选取典型的基础知识或基本 Divergent thinking is not limited to the established understanding of the multi-directional, multi-angle of thinking of information, so as to propose new problems, explore new knowledge or find a variety of solutions and results of the way of thinking. It is the basis for creative thinking and inspirational thinking. Teachers are hard-working to pay attention to the creation of problem situations in classroom teaching, put forward to stimulate students to divergent thinking, to guide students to think from the positive and negative ways, knowledge of vertical and horizontal association will improve students’ thinking ability and exploration ability is greatly beneficial of. First, the creation of the problem situation, to provide divergent thinking opportunities Divergence of mathematical knowledge is ubiquitous, but the divergence of mathematical knowledge and mathematical problems always have the strength of the points. In classroom teaching, according to the level of intellectual development of students, the breadth of teaching content requirements and the stage of the learning process to select a typical basic knowledge or basic
