Summarizes Piagetian developmental psychology, and describes a study in which trainee elementary school teachers administered Piagetian tasks to pupils. During this time the teachers were being instructed in the development of children's thought processes. Results support the continued use of the method. (AL)

Two studies on M-capacity found factor-analytical and correlational evidence that five M-capacity tests share a common source of variance and that, as subjects' increase in age, scores increase at a similar rate. Results suggest that, in the 6-11 age range, M-capacity can be measured with a battery of tests. (AA)

Argues against the claim that Piaget's theory of formal thought is invalid when used in learning high school chemistry, and suggests a way to test its validity. (GA)

This paper deals with (1) psychometric and Piagetian orientations and the different types of test each approach yields, (2) rate of progress measures, and (3) the predictability of an individual's future functioning. Advantages of the Piagetian orientation are discussed. (GO)

The sequence of development as hypothesized by Piaget has been confirmed for various groups of children by cross-sectional and longitudinal studies. Such consistency has increased interest in constructing scales based on Piaget's theory according to psychometric principles. Three major problems are discussed which present definite obstacles in the…

Presents a research study of 66 students in grades 9-12 to determine the validity of assessing cognitive level of development from a single task. Results indicate that one task is not an adequate and reliable measure of a scheme or of formal operations in general. (SL)

Examines subjects' processing in misleading test items. Suggests that the M-power for children, when assessed behaviorally, may increase with age in a discrete manner, and have the potential to generate interval scales of measurement. In addition, suggests that, in light of the results, what statisticians often consider "error of…

Examined the effects of Piagetian-like tasks' characteristics on the performance of those tasks by different age group students. Indicates the method of task presentation had an effect only on young students' performance, while numerical content had an effect on the majority of students in all grades. (Author/CW)

This book deals with cognitive development from the perspective of the author's theory of conceptual learning and development (CLD) and from a Piagetian perspective. Chapter I provides an overview of CLD theory and also identifies and discusses the Piagetian constructs of stage, groupement structures, and equilibration. Chapter II focuses on the…

CONCEPTS FOR USE IN LINKING VISUAL INPUTS TO COGNITIVE OUTCOMES WERE PRESENTED. IN ADDITION, TWO EVALUATION PROPOSALS FOR THE CONTINUING CURRICULUM DEVELOPMENT PROGRAM, EDUCATION THROUGH VISION, WERE DETAILED. SAMPLES OF THIS PROGRAM'S TEST BATTERY WERE INCLUDED IN THE REPORT WITH THE TWO EVALUATION PROPOSALS FOR DETERMINING THE EFFECTS OF THE…

Analyzed are the different stages in the conceptual evolution of infinity as developed historically through the work of Bolzano and Cantor. Results of a study of 18 to 20 year old's concept of infinity prior to instruction produced aspects of the passage between conceptual levels of infinity. (MDH)

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…

Two studies examined modifiability in intellectual functioning in older adults. The fluid-crystallized theory provided a theory base for the research. (Fluid intelligence follows a normative decline through adulthood, while crystallized intelligence remains stable or even increases.) In the first study thirty subjects (average age 69.2)…

This study sought to determine the extent to which instructional processes characterized by cognitive complexity influence the development of general cognitive abilities during the first, second, and third years of college. The sample for the study consisted of incoming first-year students at 18 four-year and 5 two-year colleges and universities…
