Two IRT-based procedures to estimate test reliability for a certification exam that used both adaptive (via a MST model) and non-adaptive design were considered in this study. Both procedures rely on calibrated item parameters to estimate error variance. In terms of score variance, one procedure (Method 1) uses the empirical ability distribution…

This collection consists of six papers, each dealing with some aspects of reliability and performance testing. Each paper has an abstract, and each contains its own references. Papers include: (1) "Using Reliabilities To Make Decisions" (Deborah J. Harris); (2) "Conditional Standard Errors, Reliability, and Decision Consistency…

After presenting a general linear model as a framework for discussion, this paper reviews five methodology errors that occur in educational research: (1) the use of stepwise methods; (2) the failure to consider in result interpretation the context specificity of analytic weights (e.g., regression beta weights, factor pattern coefficients,…

This study was designed to explore age and sex differences in self concept across a broad age span and with fairly large populations utilizing a common for all Ss. (Author/RK)

This study determined reliability of the Boehm Basic Concept Test (designed to assist the primary teacher assess basic conceptual knowledge) for rural kindergarten and first grade children. They found the rural reliability to be less than that reported for urban samples especially for middle and upper class children. The reduced reliability was…

If traditional examinations were eliminated, would course work still show the same superior students? (Author/PG)

Author discusses instruction by media presentation and advocates testing which is designed to fit the instructional methodology. (HB)

The purpose of this study was to summarize research relevant to the correction for guessing formula. Six areas are reviewed: reliability, validity, test taking behavior, statistical implications, public acceptance, scoring labor. (JB)

Results indicate that because there is not an equivalent relationship between the WISC and WAIS, classification or retardation level and prognostic formulation using these tests should be made cautiously. (Author/CB)

If one accepts the premise that the criterion measure (Musical Aptitude Profile) is a valid predictor of future musical success, then the Measures of Musical Abilities, based on these data, can be considered to possess a moderately high validity for the same purpose. (Author/CB)
