| 摘 要： | 提出了一个标准分数系统,给出了标准分数变换公式.该系统将学生的成绩分布转换为一个后验确定参数的正态分布,以后验地修复由试题差异和其他考试环境引起的分数分布异常波动,最大限度的提高了标准分数的区分度,也使该分布更接近学生学习水平的实际分布.在此基础上讨论了该标准化分数系统在学生学习水平的比较,试卷的评估等方面的应用.

| Abstract: | In this paper a standardized point system was put forward.The transfer formula were given.This system transfers students' testing points to a normal distribution whose parameters were determined afterward.Thus the abnormal disturbance was suppressed and the distinguish level of the test was improved.This is a more practical distribution.Based on this system,students' studying levels' compare and test paper's evaluation were also discussed. |
