This report presents a rationale for development of an international perspective on the role of research in the improvement of science education in particular and education in general. Costa Rica, Trinidad and Tobago, Mexico and the United States are the participating countries. Topics discussed include: (1) goals and directions for science…

The purpose of this booklet is to explain examination registration procedures and to introduce the Psychometric Entrance Examination so that students will know what to expect, what types of questions they will be asked, and how they will be expected to answer. The aim of the examination is to evaluate a variety of cognitive abilities: verbal,…

The Conceptual Learning and Development (CLD) Model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known object when it appears in a different spatial, time, or sensory perspective; (3) classificatory--generalizing that two items are alike…

It is suggested that a reader's idea structure will affect processing of incoming information. Two aspects of the idea structure are further developed--the truth value aspect and the analytic level aspect. The idea structure can be characterized by ideas consisting of propositions which are considered to be more or less true or false (beliefs), or…

Developmental patterns in one mode of formal reasoning (probabilistic reasoning) were examined in this research study, specifically: (1) to determine if developmental patterns of probabilistic reasoning could be confirmed using a large, diverse sample of subjects, and if they could be similar despite variations in the complexity of the reasoning…

Hierarchically organized knowledge about actions has been postulated to explain planning in problem solving. Perdix, a simulation of problem solving in geometry with schematic planning knowledge, is described. Perdix' planning knowledge enables it to augment the problem space it is given by constructing auxiliary lines. The planning system also…

After reading a passage from a text which explained the deep and surface approaches to learning, ninety Swedish teenagers and adults with varying levels of formal education were asked to discuss their own learning in terms of this distinction. Surprisingly, sixty-one subjects considered both approaches applicable to their own learning. After…

Research conducted at the Institute of General and Pedagogical Psychology of Moscow, and based on the premise that the development of thought processes is a direct product of the social environment, is described. As a corollary to this premise, Piaget's view that the development of the thinking process occurs in orderly fashion is questioned.…

This study tested the hypothesis that children with weaker speech ability have greater difficulties in perception, powers of reasoning and spatial orientation than children with better speech ability, and assessed the value of Apgar scores as a predictive measure of later linguistic disorders. Subjects were 100 children born in 1970 who attended…

In behavioral science research, language has been increasingly seen to reflect the concepts that the child has acquired prior to, and hence independent of, the acquisition of language. Analyses based on this idea are confined largely to words that denote clear perceptual referents. Language, however, contains many terms that have no portrayable…

The purpose of this study was to investigate the effects of cognitive abstractness levels, interpersonal perception abilities, and task type (factual or social problem solving) on group performance as measured by time consumed and adequacy of solutions. Eighteen college classes from Kearney State College participated in testing of perceptual…

This paper repudiates Jensen's hypothesis that differences in IQ scores and scholastic achievement in Negro and white children are genetically based. Specifically, Jensen's identification of IQ scores as a measure of abstract reasoning and problem solving and of levels of ability, and his evaluation of the magnitude of the genetic component in IQ…

This paper presents a study using a neo-Piagetian theory to analyze the micro-structure underlying Piaget's "control of variables" scheme. Data are presented which support the conclusion that young children are capable of acquiring and utilizing this scheme before they acquire Conservation of Weight, that is, providing (1) that the…

The level of abstraction of the message and the educational effects of five media presentations (Print, verbal sound, print/pictures, print/verbal sound, and pictures/verbal sound) were experimentally investigated. The media components were presented singly or in combination to 6th grade students in a uniformly controlled consistent environment.…

The roles of (1) the sequence of instruction and (2) cognitive ability variables were investigated using a computer-assisted instruction (CAI) course on an imaginary science of "Xenograde systems." A rationale for an information processing task analysis was developed to overcome the deficiencies of other analytic methods. The new method was found…
