在数学教学中适当让学生动手操作,不仅能有效解决数学知识的抽象性与学生思维形象性的矛盾,而且对激发学生内在学习动机,提高动手操作能力,进而培养学生合作探究意识和数学思维的发展有着积极的意义。可从一些课堂教学看来,动手操作还存在一些问题,有些操作只是一种“摆设”而已,在这种操作情境中,学生仅是进行机械的操作。有些课堂甚至出现了操作错位的现象,形式上热热闹闹,内容上乱七八糟,该讲的没讲清,
It is not only effective to solve the contradiction between the abstraction of mathematical knowledge and the image of students’ thinking in mathematical teaching, but also to stimulate students’ internal learning motivation and improve the ability of hands-on operation, so as to cultivate students’ cooperative exploration awareness and mathematical thinking Development has a positive meaning. From the perspective of some classroom teaching, there are still some problems with hands-on operation. Some operations are just a kind of “arrangement.” In this operating situation, students only perform mechanical operations. Some classes even appeared in the operation of dislocation phenomenon, the form of bustling, messy content, the talk did not tell,
