A constructive debate over the classification of child psychopathology can be stimulated by investigating the validity of different classification approaches. We examined and compared the short-term predictive validity of cluster analytic and dimensional classifications of child behavioral adjustment in school using the Behavior Assessment System…

Background: The relationship between the age of reaching infant developmental milestones and later intellectual function within the normal population remains unresolved. We hypothesised that the age of learning to stand in infancy would be associated with adult executive function and that the association would be apparent throughout the range of…

This article offers a skeletal critique of the pedagogical theory and the teaching practices arising from the work of educational innovator, Benjamin Bloom. Professor Bloom's theory and method have overtly and covertly insinuated themselves into North American educational practice over the past half-century. Their impact and influence have been…

This study examined whether scripts provide a basis for the categories preschool children use to structure their semantic memories and whether the use of taxonomies to structure memory becomes more common only after children enter elementary school. Subjects were 108 children in three equal groups of 18 boys and 18 girls children each of 4-, 5-,…

This study evaluated expert system diagnoses of examinees' solutions to complex constructed-response algebra word problems. Problems were presented to three samples (30 college students each), each of which had taken the Graduate Record Examinations General Test. One sample took the problems in paper-and-pencil form and the other two on computer.…

Three methods of equating performance assessments are compared. Equipercentile equating, item response theory (IRT) partial credit model, and IRT graded response model methods were applied to the same data using an anchor test design. Comparisons are based primarily on the resulting raw score-to-raw score tables and the effects these tables have…

In response to low graduation and transfer rates among degree-seeking students, Prince George's Community College (PGCC), in Maryland, established a campus-wide retention committee to develop recommendations to improve student achievement. A significant source of information for the committee was a longitudinal student tracking system and a…

Measures of the robustness of disease class-specific diagnostic concepts could play a central role in training programs designed to assure the development of diagnostic competence. In the pilot study, the authors used disease/sign-symptom conditional probability estimates, Monte Carlo procedures, and artificial intelligence (AI) tools to create…

This study attempts to estimate Structure of Learning Outcome (SOLO) levels in mathematics using the Partial Credit and Rating Scale models. A 30-item test comprising 10 testlets of 3 items each was designed and administered to 674 lower secondary school students. The items were arranged in a hierarchical manner, each testing SOLO levels in this…

Alternative perspectives and practices for describing and documenting teaching practice and student learning relevant to classroom reform are identified, and a framework is provided for characterizing these process-focused instruments and indicators. Diverse descriptors were used to locate documents describing instruments and procedures used to…

A state educational indicator system being developed by the Pennsylvania Educational Policy Studies (PEPS) project at the University of Pittsburgh (Pennsylvania) is described. The extensive database that has been established as part of the PEPS project includes thousands of variables that are descriptive of the 500 Pennsylvania school districts.…

This handbook represents a major effort to establish current and consistent terms, definitions and classification codes to maintain, collect, report, and exchange comparable information about persons who work in education institutions from early childhood through high school. The selection of data terms reflects the best judgment of many…

This paper offers concrete examples from recent policy research about how qualitative and quantitative methods can be combined to better address research questions. Using a conceptual framework developed by Rossman and Wilson (1985), later expanded by Greene, Caracelli, and Graham (1989), the paper discusses how the design and analysis phases of…

This activity guide, developed to provide environmental education through a series of hands-on activities geared to Raven Rock State Park in North Carolina, is targeted for grades 5, 6, and 7 and meets curriculum objectives of the standard course of study established by the North Carolina Department of Public Instruction. Three types of activities…

This research plan describes a framework for defining and developing the field of rehabilitation sciences and research opportunities for the National Center for Medical Rehabilitation Research (NCMRR) and other agencies funding medical rehabilitation research. The plan addresses the needs of both persons who are involved in habilitation and in…
