我国中学物理课程的百年建构:从实体知识到素养行动

Centennial construction of physics curriculum in middle schools of China:entity knowledge to literacy action

选取1902—2017年颁布的31份物理课程标准,将其按照时间顺序划分为4个阶段,呈现出双主体互动、课程专业化、实验导向能力培养以及多主体协同的变化趋势,揭示了我国百年物理课程的阶段发展特征和演变规律.进一步选择共现频次、词频-逆文本频率(TF-IDF)和主题关联度3个指标,筛选出最具代表性的10个关键词的年度规律,以探索百年物理课程的逻辑演进与变革特征.最后基于初高中物理课程标准特征词的TF-IDF值的百年变化,反思其核心观念的演进历程.

This paper selects 31 physics curriculum standards issued from 1902 to 2017,and divides them into four stages according to the time sequence,showing the evolution trend of double subject interaction, curriculum specialization, experiment oriented ability training and multi-subject cooperation. It deeply reveals the stage development characteristics and evolution law of physics curriculum of China. In order to explore the characteristics of logical evolution and reform of physics curriculum in the past century. Furthermore,co-occurrence frequency,term frequency-inverse document frequency(TF-IDF) and topic relevance are selected to screen out the annual rules of the most representative ten keywords,so as to explore the logical evolution and change characteristics of physics curriculum in the past century. Finally,based on the change of TF-IDF value of junior and senior high school physics curriculum standard feature words,the evolution process of its core concept is reflected.
