Generalizability theory is a modern, powerful, and broad framework used to assess the reliability, or dependability, of measurements. While there exist classic works that explain the basic concepts and mathematical foundations of the method, there is currently a lack of resources addressing computational resources for those researchers wishing to…

In this research, it is aimed to develop a valid and reliable test to determine the drawing a shape-schema and making a table levels of prospective teachers at Mathematics and Science Education, Turkish and Social Sciences Education and Basic Education Departments. In this process, a comprehensive item pool has been prepared with the table of…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the fourth-grade round of data collection. The first chapter provides an overview of the…

Based on analyses of Maclean's ranking data pertaining to Canadian universities published over the last 24 years, we present a summary of statistical findings of annual ranking exercises, as well as discussion about their current status and the effects upon student welfare. Some illustrative tables are also presented. Using correlational and…

The first step in the Validity and Reliability Study summarizes the history and purpose of California's quality rating and improvement system (QRIS), reviews findings from other QRIS evaluation studies, and describes the approach to validating the system in California. The majority of this report focuses on providing context for the California…

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)

The present study was designed to examine the construct validity, reliability, item difficulties, discrimination indices, effectiveness and efficiency of the CCAT test. (Author)

Results of a comparative study of F and Q tests, in a randomized block design with one replication per cell, are presented. In addition to these two procedures, a multivariate test was also considered. The model and test statistics, data generation and parameter selection, results, summary and conclusions are presented. Ten tables contain the…

The empirical item analysis techniques for developing short-forms of tests is questioned. Assumptions fundamental to Spearman-Brown theory are shown to offer an alternative. (Editor)

The present study was initiated to investigate the comparability of multiple-choice and true-false item formats when the time necessary to respond to each type of item was equated empirically. (Editor)

To date a theoretical basis has not been developed for determining changes in reliability when score points from random guessing are eliminated and those from non-randon guessing are retained. This paper presents a derivation of an expression for the reliability coefficient which displays the effect of deleting score components due to random…

Explores the potential utility of the MMPI 168 with two inpatient medical populations. Correlations and clinically relevant comparisons suggest that the MMPI 168 predicted the standard MMPI with a high degree accuracy. (Editor/RK)

Examines three reliability characteristics of the Harris revision of the Goodenough "Draw-a-man" Test when used with five-year-old school entrants. (Author/RK)

This investigation is concerned with the quality of classroom tests which were devised by senior university students in an education class on tests and measurement in social studies. (Author)

An algorithm for updating the means of variances of a norm group after each computer-assisted administration of a test is described. The algorithm does not require storage of the whole data set, and provides for unlimited, continuous expansion of the test norms. (Author)
