This study presents a generalized version of the residual differential item functioning (RDIF) detection framework in item response theory, named GRDIF, to analyze differential item functioning (DIF) in multiple groups. The GRDIF framework retains the advantages of the original RDIF framework, such as computational efficiency and ease of…

This research explored the use of ICT products by n = 123 pre-service teachers to complete collaborative assessments. Students responded to a questionnaire relating to the use, benefits and limitations, and what would better enable the use of ICT for collaborative assessment purposes. The ICT products favoured by students did not support some key…

Even though using group examinations aligns well with the epistemology of problem-based learning (PBL), the dilemma of using joint learning while simultaneously fulfilling individual assessment requirements in higher education make group examinations difficult to use. In this study, the aim was to explore whether an individual reflection paper…

Two-phase testing assesses individual performance (phase 1) and then allows collaborative learning within small groups (phase 2). While groups typically outperform individuals, less is known about the social decision schemes that influence member collaboration. In a classroom setting, we compared individual and group performance on a standard test…

In a fully online college introductory statistics class, we incorporated a flexible synchronous course component to provide instructor immediacy and support students who are lacking sufficient prior knowledge when a new topic is introduced. We describe a learning cycle with weekly team quizzes inspired by the readiness assurance process of…
