一些数学知识有着相对抽象的特点,在学生探索知识本源的过程中,借助直观的形象是降低学习难度,有效缩短问题和答案间距离的一种常用方法。正因为此,小学数学教学中,观察思考和动手操作成为课堂出现频率较高的活动,可是在数学课堂上,一些低效的形式化的操作活动经常可见,既浪费了宝贵的学习时间,又分散了学生的注意力,甚至起到了与预设相反的作用。那么在学生运用操作活动来进行数学探究时,应当从哪些方面来加强引导,使得操作活
Some mathematics knowledge has the characteristics of relative abstraction. In the process of students exploring the origin of knowledge, using visual image is a common method to reduce the learning difficulty and shorten the distance between questions and answers. Because of this, in elementary mathematics teaching, observation, thinking and hands-on activities have become frequent activities in the classroom. However, in the math classroom, some inefficient and formal operation activities are often seen, which is not only a waste of valuable learning time, Scattered students’ attention, and even played the opposite role with the preset. So when students use operational activities to carry out mathematical exploration, which aspects should be strengthened to guide, making the operation of living
