用信息函数法对标准参照测验作质量分析

根据项目反应理论的信息函数法,以自主开发的“现代教育和心理测量通用分析系统”为工具,对两个大规模实施的标准参照测验进行了测验质量分析。结果说明,信息函数分析法比经典真分数理论分析法,可以获得更丰富、深刻、有针对性的资料,能对项目筛选修订、测验编制开发给出有力的指导,值得大力引进、推广。     

Alpha,Dimension-Free,and Model-Based Internal Consistency Reliability

As pointed out by Sijtsma (in press), coefficient alpha is inappropriate as a single summary of the internal consistency of a composite score. Better estimators of internal consistency are available. In addition to those mentioned by Sijtsma, an old dimension-free coefficient and structural equation model based coefficients are proposed to improve the routine reporting of psychometric internal consistency. The various ways to measure internal consistency are also shown to be appropriate to binary and polytomous items.

幼儿是如何通过错误信念任务的:信念还是规则?

旨在研究错误信念任务的有效性。采用真实信念(TB)任务和错误信念(FB)任务,以知否问题和想法问题为检测指标,通过比较儿童在FB和TB任务上的表现,本研究发现4～6岁儿童在知否问题上存在正确反应、忽略推断和“是”反应偏差三种反应模式。儿童通过FB任务的方式也有三类:基于信念、基于规则,以及其它(可能是猜测或其它未知策略)。儿童在知否问题与想法问题上的通过率并无显著差异。
