我国著名数学家华罗庚早就指出,人们对数学产生干燥无味、神秘难懂的印象,原因之一是脱离实际。在教学中,运用情景图辅助教学,能具体形象地反映数量关系,使复杂的条件简单化,隐蔽关系明朗化,能为学生提供更为形象的解决问题的方法,有利于启迪学生思维探索解题思路。1.画情景图,帮助学生理解概念例:在圆柱体与圆锥体体积相等,底面积也相等的
Hua Luogeng, a famous mathematician in our country, pointed out long ago that one of the reasons why people have a dry, tasteless and mysterious impression on mathematics is that they are out of touch with reality. In teaching, the use of scene map-assisted teaching, can reflect the quantitative relationship between the specific image, the complex conditions of simplification, covert relations clear, to provide students with a more image of the problem-solving method is conducive to inspire students to explore the way of thinking Problem ideas. 1 painting scene, to help students understand the concept example: the cylinder and cone volume equal to the bottom area is also equal
