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。那么学生学习平行之前,也就是没有接触平行概念时,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,给出几组互相平行和不相交的直线让学生找出哪几组的直线互相平行时,学生竟然都找对了。通过提问,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,那么两线不
Montessori said: Education is not good for children, because you did not walk into the inner world of children. So before the students learn parallelism, that is, the concept of parallel in their minds when they do not touch the parallel concept? Through pre-class interviews, we found that although the students have not yet been in parallel, given several groups of parallel and disjoint straight When the students find out which groups of lines are parallel to each other, the students actually find the right ones. Through questioning, we found that the original students’ intuitive understanding of the concept of parallelism was that if the width of the middle of the two straight lines is the same, the two straight lines are parallel to each other. If the two straight lines are coarse and thin,
