Research results show that there are no clear grounds for assuming that students today cannot read as well as they did 25 years ago. (DS)

This report summarizes the work conducted for the Artificial Intelligence Measurement System (AIMS) Project which was undertaken as an exploration of methodology to consider how the effects of artificial intelligence systems could be compared to human performance. The research covered four areas of inquiry: (1) natural language processing and…

Research relating to the factor structure of the Sixteen Personality Factor Questionnaire (16PF) and the Clinical Analysis Questionnaire is reviewed. Different opinions about the factors measured by the 16PF are discussed. Focusing on the second-order factor level could eliminate problems with the instruments' reliability. (SLD)

Reviews four studies of the Strong-Campbell Interest Inventory (SCII) twin occupational scales and correlations developed showing the degree of similarity in results of those four studies. Findings indicate counselors need to know average female and male test-taker scores on other-sex occupational scales to make accurate SCII test interpretations.…

This research review examines the findings of those studies of empirically sound methodology which compare matching groups of abused and non-abused children. The evidence consistently demonstrates detrimental consequences in intellectual, emotional, and social development. (Author/DST)

Best-evidence synthesis was used to review 29 research papers published in English that evaluate the effects of ability grouping on student achievement in secondary schools. Six randomized experiments, 9 matched experiments, and 14 correlational studies were reviewed. Findings do not indicate beneficial effects of ability grouping on achievement.…

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

Notes that the microgenetic method has revealed new information about normally achieving children's cognition, and reviews data from three different microgenetic studies.
