S-P表分析中差异系数计算的算法优化

S—P表分析法是计算机辅助教学中一种重要的信息处理方法。差异系数是S—P表分析中反映S曲线与P曲线之间不一致程度的重要指标。通过分析差异系数,可以获得大量关于被测对象整体情况的富有价值的信息,为教学情况的分析和教学效果的改善提供依据。鉴于目前已有的一些教育信息处理专著或文献资料中有关差异系数计算程序实现上的不足,本文提出并分析了两个优化算法,并给出了它们的流程图和源代码。

Algorithm Optimization for Disparity Coefficient Calculation in the Student-Problem Chart

Student-Problem chart analysis is an important information processing method in CAI.In a S-P chart,disparity coefficient is a key index of the inconsistent between the S and P curves.We can get valuable information which can help us analyze the teaching progress and improve the teaching effect by studying the disparity coefficient.This paper proposes two optimized algorithms with flow chart and source code,which are much better than the algorithms we can found in some documents at present.
