远程教学/学习系统中的诊断与评价模型

An Diagnosis And Evaluation Model in the Distance Education /Learn ing System

在远程教学/学习系统中,诊断与评价占有特殊重要的地位,它们是开展因材施教教学/学习方式的技术基础和保障。该文给出了一个基于错误概念集交集运算的诊断模型及其相应诊断算法,同时还给出了一个具有绝对评价和相对评价两种评价体制的评价模型和实现该模型的关键技术的解决方案。目前,这些模型已经在远程汉语水平考试HSK辅导系统中实现。

In the Distance Education/Learning system,the diagnosis and evaluation components is the basis of carrying out self-adaptive education/learning.In this paper,we discuss a diagnosis model which is based on the misconception set,and give out a diagnosis algorithm.Next,an evaluation model is discussed,which includes relative evaluation and ab-solute evaluation.Then we give a solution to realize the evaluation model.At present ,we have applied them to the Dis-tance Learning System of HSK Test.
