基于Rasch理论的计算机模型教学测验的设计与应用

Design and Validation on Computer Modeling-based Teaching Assessments by Using Rasch Model

该文针对当前国内外基于计算机模型的教学测验研究较为滞后的现状，运用Rasch理论及测量设计“四基石”模型，以1600名中、美中学生为对象，通过两轮实证研究，探讨计算机模型教学测验设计的方法、过程。研究结果表明，Rasch理论及“四基石”模型能有效指导计算机模型教学测验的开发、修订，优化测验的质量，为我国相关领域的研究提供有益的启示和借鉴。

The research on computer modeling-based assessment in science education in China still lagged behind many countries. This study used Rasch measurement-based ‘Four Building Blocks’ approach to develop computer modeling-based assessment for high school students. To validate this method， we conducted three computer modeling-based measurement instruments and used for 1，600 high school students both in China and United States by two rounds. The results show effectiveness of the approach of Rasch measurement-based ‘Four Building Blocks’ as the framework for developing， revising and improving computer modeling-based assessments. Such method can also be applied to many other related contexts.
