The current study examined the relationship between test-taker cognition and psychometric item properties in multiple-selection multiple-choice and grid items. In a study with content-equivalent mathematics items in alternative item formats, adult participants’ tendency to respond to an item was affected by the presence of a grid and variations of answer options. The results of an item response theory analysis were consistent with the hypothesized cognitive processes in alternative item formats. The findings suggest that seemingly subtle variations of item design could substantially affect test-taker cognition and psychometric outcomes, emphasizing the need for investigating item format effects at a fine-grained level.

使用认知和项目反应理论方法研究技术增强的项目格式

当前的研究检查了选择多项选择和网格项目中考生认知与心理测验项目属性之间的关系。在一项采用替代项目格式的内容等同数学项目的研究中，成年参与者对项目做出反应的趋势受到网格的存在和答案选项的变化的影响。项目反应理论分析的结果与替代项目格式中的假设认知过程一致。研究结果表明，物品设计的细微变化可能会显着影响应试者的认知和心理测量结果，从而强调需要在细粒度的层次上研究物品格式的影响。
