现代教学论主张:要让学生动手做数学,而不是用耳朵听数学。如果我们能把固定的内容转化为动态的数学材料,并多给学生以放开手脚,自由游弋的空间,只要教师放开你呵护的双手,就会发现数学这门抽象的、单调乏味的学科一定会生动起来,成为立体的形象画面,使学生乐在其中,并成为会思维,会实践,有创造力的人。 Modern teaching theory: Let students do mathematics, rather than listening to mathematics with their ears. If we can transform the fixed content into dynamic mathematical material and give the students more room to free and cruise, as long as the teacher releases your hands, you will find the abstracted and boring discipline of mathematics Will be vivid, become a three-dimensional image of the picture, so that students enjoy themselves and become thinking, practice, creative people.
