Item response tree (IRTree) models are a flexible framework to control self-reported trait measurements for response styles. To this end, IRTree models decompose the responses to rating items into sub-decisions, which are assumed to be made on the basis of either the trait being measured or a response style, whereby the effects of such person…

Foreign language aptitude is defined as one's potential to learn a second language. A language learner with higher aptitude is predicted to learn more, faster, and reach a higher level of proficiency. If this is the case, one way to validate the construct of aptitude and its measure is to conduct a validation study in which measures of aptitude is…

This quantitative study focuses on the relationship between foreign language learners' aptitude and proficiency test scores. Four groups of 136 beginning students received six months of Initial Acquisition Training (IAT) in four different language categories, according to the level of complexity for an English speaker: French (Category I),…

Transactional distance (TD), the perception of psychological distance between the student and his peers, his instructor/teacher, and the learning content, has long been a prominent construct in research on distance education. Today, distance education primarily takes place over the internet, with technology mediating engagement and communication.…

This study examined the second language (L2) development of adult learners of Spanish at three levels of proficiency during and after a semester of instruction. A fundamental goal was to identify cognitive and psychosocial individual differences (IDs) that can explain between-learner variation over time in order to expand our understanding of the…

The selection of an appropriate test battery is based on its content and applicability to the vocational trainee population. This report describes the testing of a national sample of U.S. high school students with an established version of Armed Services Vocational Aptitude Battery (ASVAB), and a new, enlarged version of the same test battery.…

Test-retest reliability coefficients for the brief Career Ability Placement Survey and concurrent validity correlations against the Differential Aptitude Tests and the General Aptitude Test Battery are presented for samples of ninth and tenth grade students. (Author/JKS)

Three multiple-abilities batteries--the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery--are briefly discussed, and results of a study involving cross-correlations of the tests in these batteries are presented. (Author/JKS)

A procedure for estimating the degree to which a subtest uniquely contributes to total test performance is presented and discussed. Uniqueness analysis may be appropriately applied to any composite measurement instrument such as a multipart test or a multitest battery to assess the unique contribution of each component to the total test. The…

Data from over 1,200 correlations reported in 38 studies concerning validity of aptitude and achievement predictors of success in high school vocational programs are summarized. Predictors investigated were (1) verbal intelligence, (2) nonverbal intelligence and abstract reasoning, (3) arithmetic reasoning, (4) spatial aptitude, (5) mechanical…

To determine whether the visuospatial n-back working memory task is a reliable and valid measure of cognitive processes believed to underlie intelligence, this study compared the reaction times and accuracy of performance of 70 participants, with performance on the Multidimensional Aptitude Battery (MAB). Testing was conducted over two sessions…

The present study suggests that although the reliability of an academic aptitude test given under formula-score condition can be increased substantially through empirical option weighting, much of the increase is due to the capitalization of the keying procedure on omitting tendencies which are reliable but not valid.

An aptitude test requiring 10-minutes' administration time was administered to high school students learning Forkner, Century 21, and Gregg shorthand for the purpose of determining test validity for different shorthand systems. Validity data were obtained from approximately 2000 students. Aptitude test reliability ranged from KR20=0.88 to 0.90.…

An investigation was conducted to determine the effects of response-category weighting and item weighting on reliability and predictive validity. Response-category weighting refers to scoring in which, for each category (including omit and "not read"), a weight is assigned that is proportional to the mean criterion score of examinees selecting…

This comparison of regression discrepancy model results for learning disability identification used published IQ-achievement and reliability coefficients and generic, mean values. Use of mean IQ-achievement values resulted in higher discrepancy rates for a clinical sample. Use of both mean IQ-achievement and reliability values resulted in higher…
