Genetic and environmental correlations among 11 Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests were estimated from a sample of 143 twin pairs using the methodology of multivariate behavioral genetics. Correlations due to within-pair environmental influences were generally small, whereas those due to shared environmental…

Bilingual Navajo adolescents aged 14-16 were administered the Raven Standard Progressive Matrices (RSPM) and Comprehensive Tests of Basic Skills (CTBS). Correlations were moderate and were higher for females than for males. Norms were established for adolescent Navajos on the RSPM, a nonverbal test of intelligence and visual reasoning. (Author/GDC)

Critiques current second language courseware in view of recent trends increasing emphasis on oral proficiency. Suggests changes in the content of instructional computer programs that could be used to improve conversational proficiency. (LMO)

Description of study to determine the impact of management training on student performance focuses on the need for proper evaluation. Pre- and posttraining evaluative tools for rating managers are described, differences in ratings are analyzed, and implications for evaluating management training on interpersonal skills are discussed. (LRW)

Critics have occasionally asserted that the number of factors in the 16PF tests is too large. This study discusses factor-analytic methodology and reviews more than 50 studies in the field. It concludes that the number of important primaries encapsulated in the series is no fewer than the stated number. (Author/JAZ)

A scale developed to aid in investigation of students' perceived control at school is described, and data on its reliability, validity, and factor structure are reported. Findings reported indicate the usefulness of the perceived control scale by summarizing data from several studies. (Author/LMO)

A study of correlations between analogical reasoning and Logo programming mastery among female high school students related the results of pretests of analogical reasoning to posttests of programming mastery. A significant correlation was found between analogical reasoning and the ability to write subprocedures for use in several different…

Barcikowski has provided tables for use in situations where means are to be used as the unit of analysis. This article argues that the conditions specified for use of these tables are not practical. It explicates a methodology for carrying out analyses based on group means. (Author/JAZ)

An information-processing model of the rating process was proposed and tested by asking 18 teachers to rate 16 hypothetical student profiles formed by systematically varying information along six different dimensions. Findings revealed possible biases in teacher's ratings and indicated the importance of a theoretical model of the rating process.…

This article describes an interactive computer program that allows medical students to enter a completely free-form problem list at the keyboard and receive immediate analysis of the accuracy and thoroughness of their diagnostic impressions. (Author/LMO)

This paper presents one perspective on a new methodology of program evaluation which defines four phases corresponding to the operational life of a school program. Examples and results are discussed in terms of relevance to basic skills improvement efforts and cost-effects. (LMO)

In three experiments, fifth graders and college students watched a videotaped peer model executing two differentially effective associative-learning strategies. Observation of the model did not result in the consistent use of that strategy by fifth graders. College students did appear to benefit from the observational-learning opportunity.…

This paper presents an evaluation of the impact of the Career Development and Assessment Center for Librarians on the professional position of program participants (assessees) and on the managerial level librarians serving as assessors for the program. Changes over time in nonparticipant applicants (control group) and assessee groups are compared.…

Describes methods designed to add new studies to published meta-analysis results, focusing on a procedure using Bayesian analysis and showing how new findings complement previous meta-analysis and extend its conclusions. Also considers how studies are to be weighted, which variables are to be examined, and how often meta-analyses are to be…

The stability was evaluated of a partial correlation index, comparisons of item characteristic curves, and comparisions of item difficulties in assessing race and sex differences in the performance of verbal items on the Graduate Record Examination Aptitude Test. All three indexes exhibited consistency in identifying the same items in different…
