The Contribution of Constructed Response Items to Large Scale Assessment: Measuring and Understanding Their Impact
Peer reviewed Peer reviewed
Direct linkDirect link
Lissitz, Robert W.; Hou, Xiaodong; Slater, Sharon Cadman – Journal of Applied Testing Technology, 2012
This article investigates several questions regarding the impact of different item formats on measurement characteristics. Constructed response (CR) items and multiple choice (MC) items obviously differ in their formats and in the resources needed to score them. As such, they have been the subject of considerable discussion regarding the impact of…

Applying Multidimensional Item Response Theory Models in Validating Test Dimensionality: An Example of K-12 Large-Scale Science Assessment
Peer reviewed Peer reviewed
Direct linkDirect link
Li, Ying; Jiao, Hong; Lissitz, Robert W. – Journal of Applied Testing Technology, 2012
This study investigated the application of multidimensional item response theory (IRT) models to validate test structure and dimensionality. Multiple content areas or domains within a single subject often exist in large-scale achievement tests. Such areas or domains may cause multidimensionality or local item dependence, which both violate the…
