Based on research relating William Perry's scheme of cognitive development to foreign language proficiency, a developmental hypothesis concerning language ability is proposed. This approach suggests that lower developmental stages in the cognitive domain retard the achievement of communicative language proficiency, while higher developmental…

A study of 228 undergraduate psychology students examined the effectiveness of a prototype of "heatlab," a laboratory simulation written in PCE-PROLOG, intended for remedying misconceptions of the concepts "heat" and "temperature." The effect of varying the amount of structure on students' understanding and the…

To control for interactions in learning research due to subjects' prior knowledge of the instructional material presented, an imaginary curriculum was presented with a computer assisted technique based on Carl Berieter's imaginary science of Xenograde systems. The curriculum consisted of a classification system for ten conceptual classes of…

A media attribute approach was used in a study which hypothesized that compositional syntactic placement may bridge the processing link between the learner's cognitive capacity and the demands of a simple concept attainment task. Compositional syntactic placement refers to the relative horizontal position of the primary symbol or object within a…

This paper focuses on how educational statistics might better serve the quest for educational improvement in elementary and secondary schools. A model for conceptualizing the sources and processes of school productivity is presented. The Learning Productivity Model suggests that school outcomes are the consequence of the interaction of five…

This paper commends qualitative assessment as a significant alternative to standardized testing to determine language proficiency, placement, and instruction for ethnic first and second language adult learners in postsecondary education. Standardized tests and traditional language curriculum and methodology are rigid in instructional scope and…

Data on Scholastic Aptitude Test (SAT) scores by race are analyzed in order to explain observed differences in scores among racial and ethnic segments of college-bound test takers. A social psychological correlate that mediates between environmental factors and SAT performance is emphasized. Consideration is given to the finding that blacks at the…

In a study of the relationship between speed of information processing and general intelligence, vocational college students (50 black males and 56 white males) took eight different reaction time tests measuring the speed with which individuals perform various elementary cognitive processes, and a group test of scholastic aptitude (the Armed…

The National Longitudinal surveys (NLS) of Labor Market Behavior have been conducted by the Center for Human Resource Research at Ohio State University and supported by the Department of Labor since l966. In this paper, data from the fifth and newest NLS cohort, a national cohort of 12,686 youth who were aged 14-21 in 1979, are discussed.…

Drawing upon research on the composing process and schema theory, a study explored the effects of a generative writing task presented prior to reading on the delayed recall of fourth grade students. The purpose of the study was to determine if a writing task that required the learner to identify with events in a text to be read later would assist…

This paper reports on the relationship between English language fluency and reading achievement in California sixth grade students. The interaction between fluency and social class was examined. This interaction was found to be similar for students who spoke English only and for Spanish speakers who were fluent in English. It was diminished for…

Fifty Navy recruits were given 11 paper-and-pencil tests of cognitive styles, abilities, and aptitudes. Visual, auditory, and bimodal brain event-related potential (ERP) amplitudes were recorded from each of these subjects. Product-moment and canonical correlational analyses, as well as principal-factor analysis and varimax rotation, were…

A study was conducted to verify the findings of previous research showing that a difference in recall of superordinate and subordinate level concepts existed among various reading ability groups within the same grade of elementary school children. Instead of especially constructed passages used in the previous studies, the study used actual…

The analyses of J. E. Hunter (1983) were replicated with an expanded data set. The Hunter study, the basis of the Validity Generalization system used by the United States Employment Service, contained 515 General Aptitude Test Battery validation studies. The data set in this study included these and additional studies to bring the data set to 755…

A description of the standardized, multiple-choice Medical College Admission Test (MCAT) and how to use it is offered. Medical school admissions officers medical educators, college faculty members, and practicing physicians are active participants in selecting content, drafting test specifications, and authoring questions for the exam. The MCAT is…
