计算机化自适应测验模拟方法的研究范式与特点

The Research Paradigm and New Developments Direction of Computerized Adaptive Testing Simulation

计算机化自适应测验(CAT)在理论与实践中得到广泛应用。目前许多CAT研究可以归纳为两种研究范式:实测作答的CAT研究范式和测验作答数据模拟的CAT研究范式。CAT模拟研究方法的步骤有模型选择、题库模拟、测试起点、选题策略、测验终止策略等。CAT模拟研究的主要趋势有:选题策略、终止策略仍然是CAT研究的重点;CAT模拟研究的设计内容更适合实际测验情况;CAT研究设计采取多因素设计;模拟结果多方面综合评价等。

Computerized Adaptive Testing（CAT）is widely used in the theory and practice of the educational tests.In this paper, the CAT research paradigm was summarized as two categories, including the actual CAT research paradigm and the CAT simulation research paradigm. The CAT simulation research in the literatures could be divided into three kinds of CAT simulation forms. To sum up all the CAT simulation research literature, the CAT simulation method comprises of ten components, including the choice of the IRT model, the simulating the item pool, the starting point of CAT, item selection strategies, test termination rules, etc. This paper also summarizes some new developments and future research direction of CAT simulation. Firstly, the item selection strategies and the test termination rules are still the research hotspot. Secondly, the test design of CAT simulation is dealt with and is close to the actual situation. The multi-factor experimental design was adopted in CAT simulation. The research results of the simulation tests are evaluated on multiple attributes in CAT simulation.
