The publication reports on a statistical analysis of educational level as it affects the prediction of enlisted performance in Army training courses. Samples of the men at each of four educational levels were formed: non-high school graduation, high school graduation, some college, and college graduation. Using the Gulliksen-Wilks analysis of…

Two tables are presented showing the Idaho percentile norms on Form L of the Differential Aptitude Tests administered to students in Grade 9. (CK)

Investigated were the effects of two different methods of instruction on concept and principle learning related to organic evaluation. Also investigated was the relationship between achievement and science aptitude. The sample was selected from tenth grade students in a high school in Arizona. They were randomly assigned to a Biological Sciences…

Research literature regarding the aptitude treatment interaction (ATI) model of research is reviewed, and arguments for and against the use of the model are described. The purpose of the model is to allow a combination of desired properties of experimental and correlational methods. It yields disordinal interactions when experimental situations…

Data analysis revealed that a post-organizer had a significant facilitating effect on immediate free-recall in a controlled lecture in college statistics, but no effect on immediate content recognition or delayed free-recall. (MP)

Compared intrachild variability of five-year-old children on the Primary Mental Abilities Test when subjects reached their fifth birthday after completing at least two years of preschool enrichment. Conclusions, although qualified on the basis of limited sample size, revealed wider intrachild variability with minority children. (Author)

Methods for estimating the mean and variance of latent ability parameters of a normally distributed population that has been tested with Rasch model-calibrated test items are discussed. Methods for checking the normality of the population are also included. (JKS)

There is both intuitive and hard evidence which suggests that the quality of human learning has been shaped by evolution, biology, and genetics. Consideration of genetic argument applied to learning processes, however, leads to models of education more optimistic about the role of schooling than those derived from a genetic abilities-based theory.…

A model of the hierarchy of the tutoring processes and a review of related research. (DAG)

Discusses aptitude tests that volunteers take to match their skills, interests, and aptitudes with skills needed in specific military occupations. Describes the ASVAB (Armed Services Vocational Aptitude Battery) and what happens to ASVAB results. (CT)

To examine the reasons for declining Scholastic Aptitude Test scores during the past two decades, this paper proposes an empirical achievement model incorporating students' demographic characteristics and an expanding test-taking population. While test scores and participation rates are positively correlated, participation changes over time mask…

Describes software packages used to help prepare for the Scholastic Aptitude Test, considering features that the packages have in common as well as unique features that each package has. Also lists and ranks the products and their features in a chart (indicating system requirements and current cost). (JN)

Project Spectrum is a pilot project to fuse assessment and the curriculum of preschool and daycare programs. The article reviews standard assessment methods, describes alternative notions of intelligence, and examines the implementation of Project Spectrum in detail. (JL)

Three studies of dynamic testing of spatial aptitude were performed with training on the physical analogue of the mental task between the pre-test and the post-test. A total of 129 college students participated. Training increased spatial ability. Other experiments indicated that construct validity was influenced by dynamic testing. (SLD)
