This paper examines the concept of decalage from two cognitive-change positions (structures of logical thought and attentional and verbal mediators) and proposes an alternative explanation for decalage from a perceptual-change point of view. The term decalage is used to summarize the relation between differences in performance of various age…

The purpose of this paper is to identify how the theory and techniques of research in cognitive development can be applied to the study of learning and instruction in mathematics. Five basic research paradigms are characterized; major directions of research on number, measurement, geometry, and adolescent reasoning are identified. Most of the…

The purpose of this study was to test the effect of several cognitive development capacities on first-grade children's ability to learn basic concepts and skills of linear measurement. The cognitive capacities of interest were logical reasoning ability and information processing capacity. The hypotheses predicted that children who had not yet…

This report summarizes the work completed and outlines the plans for future research of an ongoing research program of the department of psychology at Wayne State University. The program is concerned with the identification and description of cross-cultural and developmental differences in the conceptualization and linguistic expression of…

A CONCEPT ATTAINMENT TASK IN WHICH CHILDREN ARE ASKED TO IDENTIFY A CONCEPT THROUGH DETERMINING WHICH OF A SET OF OBJECTS ARE OR ARE NOT INSTANCES OF IT WAS USED TO INVESTIGATE THEIR PROBLEM-SOLVING BEHAVIOR. OF PARTICULAR INTEREST WAS THE QUESTION OF TO WHAT EXTENT THEY USED OR LEARNED THE STRATEGY OF VARYING ONE FACTOR WHILE HOLDING ALL OTHERS…

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…

This paper explores the concept of metamemory, generally defined as the individual's knowledge of and awareness of memory. The concept of metamemory is compared to three other categories of memory and a model of what the growing child could conceivably acquire in the domain of metamemory is presented. Brief reviews of existing research relations…

The document is a training bulletin for criminal investigators, explaining the use of probability, logic, lateral thinking, group problem solving, and psychological profiles as methods of solving crimes. One chpater of several pages is devoted to each of the five methods. The use of each method is explained; problems are presented for the user to…

The purpose of this study is to develop from naturalistic field observation data a set of concepts and hypotheses related to the teaching of thinking. The study conceptualizes and relates thought processes and instructional strategies by analyzing data collected from classrooms in which the Washington University Elementary Social Science…

The purpose of this study was to (1) find if spelling approaches could be isolated and classified by the use of the JDR Spelling Checklist (an interview-type questionnaire); (2) determine the incidence of approach--visual, auditory, kinesthetic, or combination--used by students in spelling new words; (3) see if a relationship existed between the…

To test whether training in logical multiplication would improve the reading skills of "retarded readers" (children with specific language disability, minimal brain damage, dyslexia, psycho-neurological learning disability, or perceptual handicaps), this study (1) elaborated a theoretical approach to reading based on Piaget's theory of cognitive…

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…

Describes a minicourse on experimental hypotheses. The courses which treats the investigative nature of biology as a major theme, teaches nonrigorous problem-solving and engenders the excitement of self-discovery. Manipulation of variables in relation to controls, the principles of deduction and induction, and their application to selected…

In early January 2003, "Education Week" released a new report on the status of teaching in the United States and concluded that many states are taking steps to recruit and retain skilled teachers, but few efforts focus on the schools where these teachers are needed most. Drawing upon a large national database, "Quality Counts…

The purpose of this study was to investigate the effects of pair problem solving technique incorporating Polya's problem solving strategy on undergraduate students' performance in conceptual and algorithmic questions in chemistry. The subjects of this study were 89 students enrolled from two first year chemistry classes. The experimental group was…
