借助已有的课程难度定量模型N=αS/T+(1-α)G/T,以机械能部分为样例对中关两套教科书进行比较。旨在通过比较,发现中美教科书内容难度上的差异,探讨给学生减负的切实途径。
With the help of existing course difficulty quantification model N = αS / T + (1-α) G / T, two sets of textbooks of Zhongguancun were compared by taking the mechanical energy part as a sample. The aim of this study is to find out the differences in the difficulty of the contents of the textbooks between China and the United States and to explore practical ways to reduce the burden on students.
