May, Henry – Journal of Educational and Behavioral Statistics, 2006
In this article, a new method is presented and implemented for deriving a scale of socioeconomic status (SES) from international survey data using a multilevel Bayesian item response theory (IRT) model. The proposed model incorporates both international anchor items and nation-specific items and is able to (a) produce student family SES scores…

Bostrom, Ann; Barke, Richard; Turaga, Rama Mohana R.; O'Connor, Robert E. – Journal of Environmental Education, 2006
Little is known about environmental concerns and attitudes among people in former Soviet bloc countries in Eastern Europe despite widespread perceptions of severe environmental problems. The authors addressed this gap by examining Bulgarians' environmental concerns with a focus on whether the new environmental paradigm (NEP) scale can reliably…

Feldt, Leonard S.; Kim, Seonghoon – Educational and Psychological Measurement, 2006
Researchers sometimes need a statistical test of the hypothesis that two values of Cronbach's alpha reliability coefficient are equal. The situation may involve scores from two different measures administered to independent random samples or from the same measure administered to random samples from two different populations. Feldt derived a test…

Peck, Andrew C.; Ali, Rahan S.; Matchock, Robert L.; Levine, Max E. – Teaching of Psychology, 2006
Conventional wisdom is that some topics in introductory psychology are more difficult for students than others. Such wisdom seems reasonable given mismatches between students' and instructors' expectations and variations in both instructor expertise and student motivation across topical areas. Five instructors pooled students' exam performance…

Yip, Din Yan; Chiu, Ming Ming; Ho, Esther Sui Chu – International Journal of Science and Mathematics Education, 2004
This study examined gender differences in students' scientific literacy as measured by OECD-PISA. In particular, we focused on the 2437 students from 140 Hong Kong schools. Hong Kong boys' and girls' science scores did not differ overall. However, boys scored higher than girls at the higher percentiles (75th and above). Moreover, specific test…

Lorsbach, Thomas C.; Reimer, Jason F. – Journal of Genetic Psychology, 2005
The authors measured memory for individual features (objects only or locations only) and the combination of those features (objects and locations) in 9-, 12-, and 21-year-old students with a "yes" or "no" recognition task. Analysis of recognition memory performance (d' scores) revealed that although age differences existed in memory for individual…

Dillon, Frank; Worthington, Roger L. – Journal of Counseling Psychology, 2003
Five studies on the development of the Lesbian, Gay, and Bisexual Affirmative Counseling Self-Efficacy Inventory (LGB-CSI) were conducted. Exploratory and confirmatory factor analyses of an initial pool of 64 items yielded 5 factors that assess counselor self-efficacy to perform lesbian, gay, and bisexual (LGB) affirmative counseling behaviors…

Hula, William; Doyle, Patrick J.; McNeil, Malcolm R.; Mikolic, Joseph M. – Journal of Speech, Language, and Hearing Research, 2006
The purpose of this research was to examine the validity of the 55-item Revised Token Test (RTT) and to compare traditional and Rasch-based scores in their ability to detect group differences and change over time. The 55-item RTT was administered to 108 left- and right-hemisphere stroke survivors, and the data were submitted to Rasch analysis.…

M. – American Journal on Mental Retardation, 2006
The factor structure, internal consistency, and convergent validity of the Autism Diagnostic Interview-Revised (ADI-R) algorithm items were examined in a sample of 226 youngsters with pervasive developmental disabilities. Exploratory factor analyses indicated a three-factor solution closely resembling the original algorithm and explaining 38% of…

Crisp, Geoffrey T.; Palmer, Edward J. – Journal of University Teaching and Learning Practice, 2007
The appropriate analysis of students' responses to an assessment is an essential step in improving the quality of the assessment itself as well as staff teaching and student learning. Many academics are unfamiliar with the formal processes used to analyze assessment results; the standard statistical methods associated with analyzing the validity…

Bailey, Alison L.; Huang, Becky H.; Shin, Hye Won; Farnsworth, Tim; Butler, Frances A. – National Center for Research on Evaluation, Standards, and Student Testing (CRESST), 2007
Within an evidentiary framework for operationally defining academic English language proficiency (AELP), linguistic analyses of standards, classroom discourse, and textbooks have led to specifications for assessment of AELP. The test development process described here is novel due to the emphasis on using linguistic profiles to inform the …

Lievens, Filip; Sackett, Paul R. – Journal of Applied Psychology, 2007
This study used principles underlying item generation theory to posit competing perspectives about which features of situational judgment tests might enhance or impede consistent measurement across repeat test administrations. This led to 3 alternate-form development approaches (random assignment, incident isomorphism, and item isomorphism). The…

Sharifi Ashtiani, Nahid; Babaii, Esmat – Studies in Educational Evaluation, 2007
For decades traditional methods of testing have been criticized for saying relatively little reliably about students' ability as well as causing anxiety, which can negatively affect students' recall of learned information. The reform movement with its innovative approaches focusing on learner-centered education perceives assessment as an…

Al-A'ali, Mansoor – Educational Technology & Society, 2007
Computer adaptive testing is the study of scoring tests and questions based on assumptions concerning the mathematical relationship between examinees' ability and the examinees' responses. Adaptive student tests, which are based on item response theory (IRT), have many advantages over conventional tests. We use the least square method, a…

Schaeffer, Gary A.; And Others – 1993
This report contains results of a field test conducted to determine the relationship between a Graduate Records Examination (GRE) linear computer-based test (CBT) and a paper-and-pencil (P&P) test with the same items. Recent GRE examinees participated in the field test by taking either a CBT or the P&P test. Data from the field test…
