This paper extracts the characteristics of the view of ability in educational practices during the period of rapid growth in Japan, focusing on the influence of these perceptions on the Ministry of Education's educational policies. The analysis draws on the debate about "vocational aptitude tests" and "observation guidance."…

Goldhammer (this issue) proposes an interesting approach to dealing with the speededness of item responses. Rather than modeling speed as a latent variable that varies from person to person, he proposes to use experimental conditions that are expected to fix the speed, thereby eliminating individual differences on this dimension in order to make…

First- and higher-order factor analyses are explained from a conceptual rather than a mathematical perspective. A case is made for performing higher-order factor analysis when factors are theoretically related. Actual scores of 301 children on 24 ability measures are used to demonstrate interpretation of second-order factors using the FORTRAN…

The differentiation hypothesis suggests that the degree to which general intelligence ("g") pervades performance on mental tests is greater at lower ability levels. Analysis of data from Differential Aptitude Test results for over 10,500 Irish school children ages 14 to 17 years supports the differentiation hypothesis. (SLD)

In conventional practice, most educators and educational researchers score cognitive tests using a dichotomous right-wrong scoring system. Although simple and straightforward, this method does not take into consideration other factors, such as partial knowledge or guessing tendencies and abilities. This paper discusses alternative scoring models:…

The concept of aptitude is reviewed, and the uses and misuses of aptitude tests are considered. Many aptitude tests measure general ability plus certain more specialized abilities that are important for success in particular educational programs. Aptitude tests can be subdivided into: (1) group-administered aptitude tests, such as the Scholastic…

Meta-analysis of 225 hypothesis tests of measures of memory for order (MFO) and the relationship of MFO and measures of general ability demonstrate a significant relationship between MFO and standardized test scores. Fifty-one independent samples were tested. MFO task quality was a significant predictor of effect size. (SLD)

The common item equating method (weighted and unweighted) and the one-step missing data calibration method used with Rasch measurement models were compared using data from six equivalent forms of a perceptual ability test administered as part of the Dental Admission Test. Results suggest little difference among the equating methods. (SLD)

This paper discusses whether or not revisions of the Scholastic Aptitude Test (SAT) and the American College Test (ACT) have created such significant differences between the two tests that a student could conceivably score significantly higher on one than the other. The SAT has been revised to meet the needs of an increasingly diverse student…

Discusses two methods for developing and assessing fluid abilities. In the first method, students are asked to solve increasingly unfamiliar problems in a domain; and in the second, students are required to organize knowledge in new ways or view it from different perspectives. (SLD)

The Differential Aptitude Test (DAT) is a multiple aptitude battery designed to measure junior and senior high school students' and adults' ability to learn or succeed in certain areas. The test is suitable for group administration and is primarily for use in educational and vocational counseling, although it may be used in employee selection. The…
