PDF on ERIC Download full text
Anderson, Daniel; Lai, Cheg-Fei; Park, Bitnara Jasmine; Alonzo, Julie; Tindal, Gerald – Behavioral Research and Teaching, 2012
This technical report is one in a series of five describing the reliability (test/retest an alternate form) and G-Theory/D-Study on the easyCBM reading measures, grades 1-5. Data were gathered in the spring of 2011 from the convenience sample of students nested within classrooms at a medium-sized school district in the Pacific Northwest. Due to…

A Generalizability Approach To Evaluating the Reliability of Testlet-Based Test Scores.
PDF on ERIC Download full text
Lee, Guemin; Frisbie, David A. – 1997
Previous studies have indicated that the reliability of test scores composed of testlets might be overestimated by conventional item-based reliability estimation methods (R. Thorndike, 1953; A. Anastasi, 1988; S. Sireci, D. Thissen, and H. Wainer, 1991; H. Wainer and D. Thissen, 1996). This study used generalizability theory to investigate the…

Hintze, John M.; Matthews, William J. – School Psychology Review, 2004
This study examined the generalizability of systematic direct observation across setting and time. Participants included 14 students from an intact inclusionary fifth grade classroom. On-task/off-task behavior was directly observed using momentary time-sampling recording, twice a day, for 10 school days. Using Generalizability (G) theory, results…

Some Measurement Characteristics of Aggregated versus Individual Scores.
PDF on ERIC Download full text
Brennan, Robert L. – 1993
Not infrequently, investigators assume that reliability for groups is greater than reliability for persons, or that the error variance for groups is less than that for persons. Using generalizability theory, it is shown that this "conventional wisdom" is not necessarily true. Examples are provided from the course-evaluation and the…
