蒙台梭利说:教育不好孩子,是因为你没走进儿童的内心世界。那么在学生学习平行之前,也就是没有接触平行时,平行在他们心中是什么样子呢?通过课前访谈,我们发现,虽然学生还没接触平行,给出几组不相交的直线让学生找出哪几组直线互相平行时,学生竟然都找对了。进一步了解,发现原来学生对平行概念最初的直观认识是:如果两条直线“中间地带”粗细一致,那么两条直线互相平行;如果两条直线“中间地带”有粗有细,那么两条 Montessori said: Education is not good for children, because you did not walk into the inner world of children. So before the students learn to parallel, that is, without parallelism, parallelism in their minds like what? Through pre-class interviews, we found that, although the students have not yet been in parallel, given several sets of disjointed straight lines for students to find out Which groups of straight lines parallel to each other, the students actually find the right. Further understanding and found that students originally intuitive understanding of the concept of parallel is: If the two lines “middle zone ” thickness, then the two lines parallel to each other; if the two lines “middle zone ” has coarse and fine, Then two
