摘　　要：学科知识是一些相互关联的知识对象所构成的系统。类比社会必要劳动时间决定商品价值的经济学理论,提出了一种基于学习时间的知识量计算方法,该方法以达到社会平均合格成绩所需要的社会平均学习时间作为计量依据,可以定量的表达知识所含的信息量大小。最后,通过实例对计算方法进行了说明。Subject knowledge is a system composed of some interrelated knowledge objects.By analogy with the economic theory that the necessary labor time of society determines the value of goods,this paper proposes a method of calculating the amount of knowledge based on learning time.This method takes the social average learning time needed to achieve the social average qualified achievement as the basis of measurement,and combined with the real achievement of learners,defines the concepts and quantitative expressions of learners'cognitive quantity.Finally,a calculation method is illustrated by examples.

关 键 词：学科知识 知识量 社会平均学习时间
