Peer reviewed Peer reviewed
Direct linkDirect link
Miyazaki, Yasuo; Kamata, Akihito; Uekawa, Kazuaki; Sun, Yizhi – Educational and Psychological Measurement, 2022
This paper investigated consequences of measurement error in the pretest on the estimate of the treatment effect in a pretest-posttest design with the analysis of covariance (ANCOVA) model, focusing on both the direction and magnitude of its bias. Some prior studies have examined the magnitude of the bias due to measurement error and suggested…

The Effect of Differential Motivation on IRT Linking
Peer reviewed Peer reviewed
Direct linkDirect link
Mittelhaëuser, Marie-Anne; Béguin, Anton A.; Sijtsma, Klaas – Journal of Educational Measurement, 2015
The purpose of this study was to investigate whether simulated differential motivation between the stakes for operational tests and anchor items produces an invalid linking result if the Rasch model is used to link the operational tests. This was done for an external anchor design and a variation of a pretest design. The study also investigated…

Agent-Based Simulation of Learning Dissemination in a Project-Based Learning Context Considering the Human Aspects
Peer reviewed Peer reviewed
Direct linkDirect link
Seman, Laio Oriel; Hausmann, Romeu; Bezerra, Eduardo Augusto – IEEE Transactions on Education, 2018
Contribution: This paper presents the "PBL classroom model," an agent-based simulation (ABS) that allows testing of several scenarios of a project-based learning (PBL) application by considering different levels of soft-skills, and students' perception of the methodology. Background: While the community has made great advances in…

Evaluation of the CATSIB DIF Procedure in a Pretest Setting
Peer reviewed Peer reviewed
Direct linkDirect link
Nandakumar, Ratna; Roussos, Louis – Journal of Educational and Behavioral Statistics, 2004
A new procedure, CATSIB, for assessing differential item functioning (DIF) on computerized adaptive tests (CATs) is proposed. CATSIB, a modified SIBTEST procedure, matches test takers on estimated ability and controls for impact-induced Type 1 error inflation by employing a CAT version of the IBTEST "regression correction." The…

The Use of Live Simulation in Teaching the Mental Status Examination to Medical Students.
Peer reviewed Peer reviewed
Rubenstein, Ralph; And Others – Journal of Medical Education, 1979
An approach to teaching the mental status examination to sophomore medical students at the Wayne State University School of Medicine incorporates live simulations, a detailed handout, a pretest and post-test, and a short lecture and discussion. The data suggest significant post-test gains, but there were negative findings regarding the handout.…
