类比归纳法就是将最基本的概念、规律——教材中各个知识点进行分类、归纳、比较,以加强识别和记忆,达到牢固掌握基础知识的方法。下面以光学知识为例介绍这种方法在复习中的应用。按光的性质归类光在同一种物质里传播的路线是直的,光在真空(或空气)中的传播速度是3×105千米/秒,说明光的传播是有方向性的,故在画光路图时,必须用箭头标出光的传播方向。由于光的直线传播,所以有小孔成像与影子的
Analogy induction is the most basic concepts, laws - teaching materials in the various points of knowledge classification, induction, comparison, in order to strengthen the identification and memory, to firmly grasp the basic knowledge. The following uses optical knowledge as an example to introduce the application of this method in reviewing. According to the nature of the light classified in the same species of light propagation path is straight, the light (or air) in the propagation velocity is 3 × 105 km / s, indicating the light is a directional transmission, it is When drawing a lightpath, the direction of light propagation must be marked with an arrow. Because of the straight line of light, there are holes for imaging and shadowing
