众所周知,物理作为一门自然科学,在学习中有许多知识点需要用模型、图形、公式来描述.这就决定了物理教材必然有许多插图,这些插图能够达到文字无法企及的教学效果.而国内教材在插图水平上尚有改进之处,笔者接触过几本国外教材,通过对比举出几例,和读者探讨。例1、在开普勒定律教学中,人教版教材利用图1中的阴影面积相等说明:行星与太阳的连线在相等的时间内扫过的面积相等,但这幅图明显是为了讲授知识主观绘制,没有什么能够给读者留下什
As we all know, physics as a natural science, in learning a lot of knowledge points need to use models, graphics, formulas to describe.This determines the physical textbooks must have many illustrations, these illustrations can achieve the teaching of text can not match.And the domestic There is still some improvement on the level of illustration in the textbook, I have contacted several foreign teaching materials, by comparing several cases cited, and the reader to explore. Example 1 In Kepler’s Law Teaching, the PEP textbook uses the same area of shadows in Figure 1 as the illustration: The area of the planets and the sun that sweeps over the same time is the same, but the picture is clearly for teaching Subjective drawing of knowledge, nothing to leave the reader left behind
