摘　　要：文章基于影响物理知识点难度的五个维度,建立了物理知识点难度定量分析模型,定义了各维度赋值方法。通过学习者主观难度问卷调查,采用因子分析和线性回归分析初步验证模型有效性,验证结果表明:知识点难度与知识点深度和广度有关,深度对难度的影响程度高于广度。物理知识点难度模型的建立不仅可以对知识点进行定量分析,还可作为教材的编写和改革的重要参考,指导教学设计。Based on the five dimensions that affect the difficulty of physical knowledge points,this paper establishes a quantitative model to analyze difficulty of physical knowledge points,and defines the method of assignment of each dimension.Through learners' subjective difficulty questionnaire,using the factor analysis and linear regression analysis to do preliminary verification of model validity,the verification results show that the difficulty of knowledge points related to its depth and breadth,and the depth has more influence on difficulty than breadth.The establishment of Physical Knowledge-point Difficulty model can not only make quantitative analysis of knowledge points,but also serve as an important reference for the compilation and reform of textbooks,and guide the teaching design.
