摘要
在数学“图形与几何”教学中,教师要引导学生把主要的思维力量聚焦于过程探究、方法思考等层面上来,以发散学生思维,促进学生思维发展。要积极实施物图沟通,使图形表象更明确;图文并行,使探索过程更明晰;看思交融,使问题研究更简明;具象活动,使知识学习更深刻。这样能使知识建构更完美,让学生思维“可视”,促进他们对几何知识理解的深入,更好地解读图形的本质属性,使得几何图形在学生心中真正“活”起来。
In the teaching of"graphics and geometry"in mathematics,teachers should guide students to focus their main thinking power on process exploration and method thinking,so as to divergent students'thinking and promote the development of students'thinking.We should actively implement the communication between objects and drawings to make the graphic representation more clear;parallel graphics and texts make the exploration process more clear;the blending of seeing and thinking makes the problem research more concise;concrete activities make knowledge learning more profound.This can make the knowledge construction more perfect,make students'thinking"visible",promote their in-depth understanding of geometric knowledge,better interpret the essential attributes of quasi graphics,and make geometric graphics truly"live"in students'hearts.
