摘要
对于教育测评所积累的大量数据,通过数据挖掘技术能产生出对学生、教师、教育管理者有用的知识。为此,从教育测评的目的、数据准备、数据积累方法,到数据的知识挖掘等几个方面,系统地研究了教育测评的知识发现的过程,并分别就三种需求的知识发现方法进行探讨,以改变教育测评仅能提供定性的结论而不能发现知识的状况,丰富教育测评的内涵。
As for a large amount of data accumulated in education evaluation, useful knowledge for students, teachers and education administrators can be produced through data mining technology. Therefore, from the purpose of the education evaluation, to the data preparation, data accumulation method and data knowledge mining, the process of knowledge discovery in education evaluation system is systematically researched. Three kinds of knowledge discovery methods are respectively discussed, to change the situation that the education evaluation can only provide qualitative conclusion and can not find the status of knowledge, and it also enriches the connotation of education evaluation.
