知识点认知规律的实验研究

知识点是人的认知单位，人学习知识，必须以知识点为单位、逐个知识点地学习。本实验以概念学习为例，研究了人一次学习一个知识点与同时学习两个知识点时的成绩差异。研究结果表明，1. 在概念中的信息组块数不超过短时记忆容量的前提下，一次学习一个概念，构成概念的信息组块数对概念掌握影响不显著。2.在同样条件下，一次学习一个知识点的成绩好于同时学习两个知识点的成绩，从而验证了知识点认知规律。

An Experimental Research on the Cognitive Law of Knowledge-points

The acquisition of knowledge should be based upon knowledge points as a unit and learn them one by one.This experiment,taking concept learning as its sample,attempted to study the different achievements between one concept learning and two concept simultaneous learning.The result reveals:1.When the information chunks forming the concept are not out of the short term memory span,learning one concept at a time is not affected notably by the number of the information chunks.2.Under the same condition,the achievement of one concept learning is much better than that of two concepts at a time learning.So the cognitive law of knowledge points is proved.
