数学教学是学生积极参与、交往互动、共同发展的过程。因此,在数学教学过程中,教师只有精心组织学生积极动手操作、动脑思考、动口表述,真正参与到数学思维活动中,才能激活学生的思维,拓展学生的思路,促进学生思维能力的全面发展。一、动手操作,以“象”促思人们首先是用形象思维来认识世界的,而形象思维是借助“表象”来思维的。因此,教者首先应注意数学知识的物质化,即将准备学习的抽象知识物化为看得见摸得着的学习 Mathematics teaching is a process in which students actively participate, interact and develop together. Therefore, in the process of mathematics teaching, teachers can only activate students ’thinking, develop students’ thinking and promote the all-round development of students ’thinking ability only through meticulous organization of students’ active hands-on operation, brain-thinking and verbal statements and their true participation in mathematical thinking activities . First, the hands-on operation to “Like ” to promote people first and foremost is to use the image of thinking to understand the world, while the image of thinking is to use “appearance ” to think. Therefore, the teacher should first pay attention to the materialization of mathematical knowledge, that is, the abstract knowledge to prepare for learning materialized as tangible learning
