This two-phase experiment was conducted to determine: (1) whether foreign language aptitude as measured by standard aptitude tests (Pimsleur Language Aptitude Battery, Carroll-Sapon Modern Language Aptitude Test) can be significantly increased by training, and (2) whether increases in language aptitude so obtained would result in better language…

This book provides a collection of 191 mathematical problems aimed at the advanced high school student level and above. Problems cover general mathematical areas including plane geometry, three-dimensional geometry, number theory, algebra, combinatorics and graph theory, and a number of miscellaneous questions that combine mathematical…

The paper compares "standard" mathematics training with the normal human experience of "contextual learning." Contextual understanding permits children to learn various patterns of events and circumstances in their surroundings. The conclusion is that every child is a competent contextual learner, and functions very effectively learning language…

A discussion of tentative generalizations that developers of instructional materials can use on aptitude-treatment interaction. The author combines what research findings seem to indicate along with theories about how individuals learn and process information. (Author/HB)

Factor analyses of the McCarthy Scales were performed on separate groups of black and white children to assess the comparability of the underlying structures and to evaluate the construct validity of the MSCA for each racial group. There was evidence of the instrument's construct validity for each racial group. (Author)

The Occupational Report (OR) is a computer-generated report that provides occupational information for planning vocational rehabilitation services. Input data includes raw scores from the USES (United States Employment Service) Interest Inventory and raw scores from either the General Aptitude Test Battery or the Non-Reading Aptitude Test Battery.…

Analysis of variance (ANOVA) and multiple regression are two of the most commonly used methods of data analysis in behavioral science research. Although ANOVA was intended for use with experimental designs, educational researchers have used ANOVA extensively in aptitude-treatment interaction (ATI) research. This practice tends to make researchers…

The purpose of this study was to assess the effects of correlated dimensions and differential ability on one dimension on parameter estimation when using a two-dimensional item response theory model. Multidimensional analysis of simulated two-dimensional item response data fitting the M2PL model of M. D. Reckase (1985, 1986) was conducted using…

The degree to which human intelligence can be improved by psychological and educational means will depend largely upon the level of analysis accepted as representing intelligence. Training and structured learning can enhance achievement in the form of knowledge and skills. Traditional Intelligence Tests (IQ) are fairly broad samples of…

This paper outlines a schema for the systematic investigation of individual differences in learning through the use of aptitude-treatment interaction studies, and provides an approach to incorporating these studies into an ongoing evaluation system. (Editor)

A study of children enrolled in a year-round preschool program for the "culturally disadvantaged" in Tampa, Florida revealed that children with defective vision performed more poorly on both the Peabody Picture Vocabulary Test and Metropolitan Readiness Test. (Author/JM)

The study involving 614 hearing impaired students investigated the adequacy of time limits currently followed in the administration of two subtests of the Differential Aptitude Test battery when used with young deaf students. Thirty-six students who did not complete the Space Relations portion of the battery under the timed condition, and 11 who…

As test standards and research literature in general indicate, definitions of test bias and item bias vary considerably, as do the results of existing methods of identifying biased items. The situation is further complicated by issues of content, context, construct, and criterion. In achievement tests, for example, content validity may impose…

The guidelines for vocational assessment of handicapped students are intended to help Texas educators fulfill requirements that a vocational assessment be completed before a handicapped student is placed in a vocational education program. Three levels of assessment data are distinguished: Level I data which are collected by special education…
