俗话说:“眼过千遍,不如手过一遍。”在小学数学教学中,恰当地让学生动手操作是很有益的,让学生在课堂上动手操作是一个手脑并用的过程,是解决数学知识抽象性与小学生思维形象性之间矛盾的一种有效手段,且能使教学达到事半功倍的效果。但反思平时的课堂教学,我发现课堂动手操作存在有效性缺失现象。如,有了动手操作就没了数学思考。尤其是低年级学生年龄小,动手能力比较弱,课堂上动手摆一摆、动一动、做一做,忙着 As the saying goes: “Eye over a thousand times, it is better to hand over it.” In primary school mathematics teaching, it is very useful to allow students to operate properly, so that students in the classroom hands-on operation is a brain and use of the process is Solve the contradiction between the abstraction of mathematical knowledge and the thinking image of pupils, and can make teaching achieve a multiplier effect. However, reflecting on the usual classroom teaching, I found that there is a lack of validity in classroom hands-on operation. For example, with the hands-on no mathematical thinking. In particular, the younger students are young and have a weak ability to practice. They have to put their hands on the classroom
