Peer reviewed Peer reviewed
Direct linkDirect link
Johnson, Evelyn S.; Zheng, Yuzhu; Crawford, Angela R.; Moylan, Laura A. – Journal of Experimental Education, 2022
In this study, we examined the scoring and generalizability assumptions of an explicit instruction (EI) special education teacher observation protocol using many-faceted Rasch measurement (MFRM). Video observations of classroom instruction from 48 special education teachers across four states were collected. External raters (n = 20) were trained…

Till, Hettie; Ker, Jean; Myford, Carol; Stirling, Kevin; Mires, Gary – Advances in Health Sciences Education, 2015
The authors report final-year ward simulation data from the University of Dundee Medical School. Faculty who designed this assessment intend for the final score to represent an individual senior medical student's level of clinical performance. The results are included in each student's portfolio as one source of evidence of the student's…

Arthurs, Leilani; Hsia, Jennifer F.; Schweinle, William – Journal of Geoscience Education, 2015
We developed and evaluated an Oceanography Concept Inventory (OCI), which used a mixed-methods approach to test student achievement of 11 learning goals for an introductory-level oceanography course. The OCI was designed with expert input, grounded in research on student (mis)conceptions, written with minimal jargon, tested on 464 students, and…

Quantitative Differences in Retest Effects across Different Methods Used to Construct Alternate Test Forms
Peer reviewed Peer reviewed
Direct linkDirect link
Arendasy, Martin E.; Sommer, Markus – Intelligence, 2013
Allowing respondents to retake a cognitive ability test has shown to increase their test scores. Several theoretical models have been proposed to explain this effect, which make distinct assumptions regarding the measurement invariance of psychometric tests across test administration sessions with regard to narrower cognitive abilities and general…

Wang, Ning; Wiser, Randall F.; Newman, Larry S. – 1999
Job analysis has played a fundamental role in developing and validating licensure and certification examinations, but research on what constitutes reliable and valid job analysis data is lacking. This paper examines the reliability and validity of job analysis survey results. Generalizability theory and the multi-facet Rasch item response theory…
