苏霍姆林斯基曾说:在手与脑中间有着千丝万缕的联系。这些联系起着两个方面的作用:手使脑得到发展,使它更加明智;脑使手得到发展,使它变成创造的聪明工具和镜子。而在小学数学教学中,教师要结合数学内容,积极地创造条件,有意识地引导学生动手操作,促使学生左右脑平衡发展。一、操作有利于知识的内化学生通过对学具的操作,不仅能使抽象概念具体化,而且能激发学生的学习兴趣,满足他们强烈的表现欲望,既有利于 Sukhomlinski once said: There is an inextricable connection between the hand and the brain. These connections serve two purposes: hands make the brain grow and make it smarter; the brain develops hands that make it a clever tool of creation and mirror. In primary school mathematics teaching, teachers should combine mathematics content, create conditions actively, and consciously guide students to operate hands-on, to promote balanced development of the left and right students. First, the operation is conducive to the internalization of knowledge Through the operation of learning tools, students can not only make concrete conception of abstraction, but also stimulate students’ interest in learning to meet their strong desire to express, both beneficial
