基于概念图的高职电子技术课程评价实践与分析

Research on the Evaluation for Electronic Technology Curriculum Based on the Concept Diagram in Higher Vocational Schools

概念图是组织和表征知识的工具,可以用来检测学生对知识的记忆能力、理解程度和应用创新能力。但目前概念图在高职生学业评价领域中的研究还为数不多。通过对不同形式的概念图检验试题设计不同的评分标准,并应用对比实验,从试题的信度、难度、区分度和效度等方面对概念图的评价效果进行分析,试验数据表明,在高职学业成就评价中使用概念图评价方法是可行并且有效的。

Concept diagram is a tool for knowledge organization and characterization, and can be applied for testing stu dents＇ memory ability, understanding degree as well as application and innovation abilities, but the research on concept di agram in academic evaluation field of higher vocational school students is few so far. Thus, the paper designed the differ ent marking criteria in light of different forms of concept diagram testing questions, applied the contrast experiment, and analyzed the evaluation effect of concept diagram from the reliability, difficulty, partition degree and validity of testing questions. The results show that it is feasible and effective to apply concept diagram evaluation method in academic achievement evaluation of higher vocational school students.
