The study analyzes students' performance scores in formative assessments depicting the individual and group settings. A case study design was adopted using quantitative approach to extract data of 198 undergraduate students. Data were analyzed quantitatively using descriptive statistics--means and frequencies; spearman correlations, multiple…

The purpose of this study was to evaluate the effectiveness of group testing as a pedagogical technique to enhance learning in a difficult subject such as statistics. Individual test scores were compared to their group test scores for the same, identical test. A t test was used to compare the scores for 157 randomly selected MBA students enrolled…

Procedures to be applicable in situations in which large numbers of individuals are tested or in situations where multiple measures are taken. (Author/CB)

Compares the performance of learning disabled students on the WISC-R and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery. This study finds that learning disabled subjects performed more poorly on the Tests of Cognitive Abilities than on the WISC-R. (Author)

The difficulties in comparing profile variability (a measure of test scatter) are briefly discussed and the limitations of current techniques pointed out. Test scatter is defined as individual variation in test scores between or within various psychological and educational tests. Currently, no statistical technique for the comparison of profile…

Four techniques for assessing differences between least-squares estimators of regression coefficients from group and individual-level data are summarized. The utility and suitability of all four approaches are discussed when (1) data are grouped by a nominal characteristic; (2) there are multiple regressors; or (3) individual-level data cannot be…

This research investigated the use of the Rasch simple logistic model in obtaining test-free ability estimates. Raw-score ability estimates were influenced by the difficulty of the items used in measurement but Rasch ability estimates were relatively independent of the item difficulty. (Author/CTM)

The model for educational measurement developed by George Rasch, a Danish psychometrician, is reviewed and its application to occupational educational testing discussed. The Rasch model is an adaptation from the theory of latent trait analysis. According to it, answering an item correctly is a function of the difficulty of the item and the ability…

Simulated Occupational Choice (SOC) was developed to measure competencies in career decision-making. SOC is a structured, individually-administered simulation exercise designed to elicit career decision-making behaviors and enable those behaviors to be observed, recorded, and scored in meaningful ways, particularly for diagnosis. It was…

This article presents evidence of the reliability and validity of a new paper-and-pencil test of proportional reasoning, Paper-and-Pencil Balance Beam Test. A Total of 627 individuals, aged 8-47, participated in the 3 studies discussed. Results support previous research which correlates performance on proportional reasoning problems with…

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…

This report describes the midterm and final tests administered to pupils in the Quality Assurance classes using the First Year Communication Skills Program. The tests included both selected and constructed response items and were designed to be individually administered to pupils. The results are reported for each eight outcome subscores (selected…

The Mastery-Learning test model is extended. Methods for estimating prior probabilities are described. The use of an adjustment matrix to transform a probability of mastery measure and empirical methods for estimating adjustment matrix parameters are derived. Adjustment matrices are interpreted as indicators of instructional effectiveness and as…

Monte Carlo simulation procedures were used to study the psychometric characteristics of two two-stage adaptive tests and a conventional "peaked" ability test. Results showed that scores yielded by both two-stage tests better reflected the normal distribution of underlying ability. Ability estimates yielded by one of the two stage tests…

The present study was undertaken to assess whether training that was known to produce transfer within the Cognition of Figural Relations (CFR) domain of Guilford's Structure-of-Intellect model would also produce transfer to other operations in Guilford's model. Fifty subjects, matched for pretest score on a double classification task, were…
