Test Administration Mode Effects of Hands-On-Based Test Versus Paper-and-Pencil-Based Test

• In Event: 66.077 - Methodological Considerations of Rasch Models

Abstract

Multiple modes of assessments can be utilized to assess student applying scientific practices, in the context of disciplinary core ideas and crosscutting concepts. However, the unique features of different assessments may lead to test mode effects. Based on a measurement instrument involving two test administration modes (i.e., a paper-and-pencil test and a hands-on based test), for measuring student proficiency in science, as expected in the NGSS, using Many-Facet partial credit Rasch model, this study aims to investigate the test administration mode effects, as well as the interaction effects between test mode and NGSS trait, gender and trait/mode. The results indicated that there are significant test administration mode ef fects and interaction effects between mode and trait, gender and trait.
