Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

The nature of the relations between traditional psychometric and Piagetian instruments is analyzed, in order to provide information relevant to the question of which type of test or combination of them will provide the most useful information to those seeking to construct and maintain optimal learning environments. Four hypotheses are posed: (1)…

An exploratory study of a prison community is presented. The study employed a three-phase design: (1) a pre-survey of the prison community, (2) limited intervention, based on findings of the pre-survey, and (3) a post-survey to determine effects of intervention and to validate findings of the pre-survey for which no intervention had been designed.…

Describes the reasoning patterns characteristic of the abstract thinking required for higher levels of school science. Discusses control and exclusion of variables, ratio and proportion, conservation involving models, compensation and equilibrium, correlation, probability, combinatorial thinking, coordination of frames of reference, and…

First-year University of Hong Kong students were subjects in a study using sex, verbal intelligence, personality, and attitudinal variables as predictors of English language skills. Results showed that levels of proficiency in reading, writing, listening, and speaking were independent of one another. (LMO)

Discusses relation between verbal ability and metamemory and how these two factors relate to the later recallability of material.
