Cognitive development as it progresses from concrete to abstract thinking is discussed as it relates to adolescent youth and the early secondary curriculum. Piagetian tests administered to a group of freshman and sophomore high school students revealed that many had difficulty with those scholastic activities requiring formal reasoning. Three…

Hitherto, theories of similarity have restricted themselves to judgments of what might be called literal similarity. A central thesis of this paper is that a complete account of similarity needs also to be sensitive to nonliteralness, or metaphoricity, an aspect of similarity statements that is most evident in similes, but that actually underlies…

This is one of a series that is a collection of translations from the extensive Soviet literature of the past 25 years on research in the psychology of mathematics instruction. It also includes works on methods of teaching mathematics directly influenced by the psychological research. Selected papers and books considered to be of value to the…

Four prime time television programs--"Charlie's Angels,""Little House on the Prairie,""Grizzly Adams," and "Lou Grant" --were rated by university students for their portrayal of moral reasoning and values. Data were obtained from three episodes of each program by randomly assigning raters to one of two viewing groups, both of which used an…

An experiment concerning children's conceptions of price was conducted to investigate the influence of the context of a problem on its apprehension. A total of 120 children of several age groups (nursery school, grades 2, 4, and 6) were interviewed individually. An initial question was asked ("Why does a bun cost about one Swedish…

The purposes of this experiment were: (1) to examine the development of categorical representations by comparing the performance of children of various ages to adults, and (2) to compare the internal representations of basic level and superordinate categories. Subjects were 48 children (in second, fourth and sixth grades) and 16 adults. The…

Reading lessons were observed, taped, and analyzed to determine how teachers' questioning strategies contribute to students' ability to comprehend materials read. The kinds of thinking elicited by teachers' questions were investigated by means of a classification scheme developed which included recognition, recall, translation, conjecture,…

A theory of the nature of mental abilities is presented. In this theory, mental abilities are hierarchically organized into four progressively deeper levels--the levels of composite tasks, subtasks, information-processing components, and information-processing metacomponents. Composite tasks can be decomposed into subtasks, subtasks into…

This theoretical paper reevaluates the Piagetian tradition in the study of propositional reasoning. Piaget's assertion that children's logic, prior to the stage of formal operations, is structurally adequate for dealing with objects and their properties, but is inadequate for fully competent propositional reasoning, is challenged on three grounds:…

This paper argues in favor of using interactional strategies in the study of formal operations reasoning. Interactional designs allow a convergent approach to specifying processes underlying the interaction of variables. In contrast, current methodologies contain two inherent disadvantages: they have limited utility in specifying the processes…

This self-instructive workbook focuses on a set of propositional abilities related to learning. It utilizes written materials, manipulative materials, videotapes, and students, and is supplemented by a program and support system which includes instruction, teaching experiences for practice, discussions, and individual conferences. The three major…

The purpose of this study was to provide a more complete understanding of the storage and retrieval processes of developmentally different youngsters. Forty-four second and fourth grade subjects were given a lesson consisting of 25 facts to learn and remember. Half of the group learned the facts in a context containing superordinate statements…

This paper presents a study designed to determine if groups of concrete and formal operational children can be identified through the technique of cluster analysis, using a battery of Piagetian tasks. A Total of 64 subjects, 8 boys and 8 girls from each of the second, fourth, sixth, and eighth grade levels, were selected from a public elementary…

This study examines the effects of using different classes of ratios on adolescent performance on proportionality problems. Problems of the form a/b = c/x varied on four dimensions: size of a/b, equality or inequality of b and c, complex or simple fractions, and form of the test. Tests consisted of six proportionality problems involving sizes of…

Two experiments compared the cognitive maps (mental representations of the spatial environment) of first graders, fifth graders and college students, and investigated developmental changes in the ability to manipulate cognitive maps mentally. In the first experiment, subjects were asked to move from stationpoint to stationpoint and at each, to…
