项目反应理论在高职学生技能测试中的应用研究

Research on the Application of Item Response Theory in Skill Test of Higher Vocational College Students

通过对当前高职院校在学生技能测试中采用的基于经典测量理论的考试系统进行研究发现,传统考试系统由于存在一些先天不足,通常不能真实评价学生掌握技能的水平。引入项目反应理论的计算机自适应考试系统可以根据考生的能力水平自动抽取相匹配的试题进行测验,效率更高、结果更准确。这也是有效提升高职素质教育水平、精准定位知识短板、全面提升学生技能水平的有效手段之一。

Through the research on the test system based on classical measurement theory in the current vocational college students'skill test,it is found that the traditional examination system cannot evaluate the real level of students'mastering skills because of some inherent deficiencies.The introduction of computer adaptive test system based on item response theory can automatically extract the matching test questions in accordance with the examinee's ability,which is more efficient and accurate.It is also one of the effective means to effectively improve the quality education of higher vocational education,accurately locate the knowledge insufficiency,and comprehensively improve the skill of students.
