复式统计表的知识,是讲给学生听还是让他们自己体会,教师大都选择后者,但教学达成度不甚理想,根本原因在于学生没有产生把单式统计表合成复式统计表的自觉性。而要解决这一问题,就要让学生在“慢慢走,欣赏啊”的教学展开中渐渐体悟,积累到一定程度后教师再提出一个突破性的问题,让学生的学习心愿由此“爆发”。
The knowledge of the compound statistic table is to tell the students to listen or let them understand themselves. Most of the teachers choose the latter. However, the teaching achievement is not ideal. The fundamental reason is that students do not have the consciousness of synthesizing the compound statistic table into a single form. In order to solve this problem, we must let the students gradually understand the teaching of “walking slowly and appreciating ah”. After accumulating to a certain extent, teachers again propose a breakthrough problem so as to make the students’ learning wish “break out”.
