A teaching experiment with six third graders to analyze their ways of operating while solving fraction tasks. Children's quantitative reasoning with fractions was based on their quantitative reasoning with natural numbers. Presents the constructive itinerary of one of the most advanced children in the group. (Contains 44 references.) (Author/MDH)

Reports a study of 913 Israeli students in grades 7-12 from randomly chosen heterogeneous homeroom classes to investigate students' Piagetian cognitive levels using a video-based test. Results indicate that less than 50 percent of high school students have mastered formal operational reasoning. (MDH)

Examines two theoretical approaches on how we understand our own and others' minds: a causal explanatory and an interpretive social approach. Explores the relations between these views and suggests that the real challenge of the cognitive revolution is to unite the two approaches, to achieve a causal naturalistic account of the acquisition and…

Suggests that a better understanding of the development of children's theories of mind, requires theoretical perspectives that do not privilege the child who conceptualizes or actively participates in social interactions. Proposes that a better understanding of the relationships among brain, psyche, behavior, and culture should be promoted. (AA)

Examines Astington and Olson's proposal under the context of von Wright's and Hempel's theories of explanation and understanding. Suggests that for taking children's meaning making seriously, researchers should find a principled way to acknowledge the role of interpretation in scientific thinking even in the making of explanation itself. (AA)

Examines the relationship between causal-explanatory and interpretive-hermeneutic approaches to how we understand our own and others' minds. Suggests that the two approaches discussed by Astington and Olson are mutually enlightening but, contrary to the proposed position, are irreducible to each other. (AA)

Points out agreement that the concepts a child acquires are variants of those exemplified by the cultures in which they grow up. Suggests, however, that learners interpret these cultural practices in terms of models causally determined by their cognitive or representational capacities and by the stock of concepts currently available. (AA)

Building on the assumption that the most important skill for the future is the ability to think, an initial framework for an intellectual processes curriculum theory is described. A definition of intellectual processes is formulated first: Intellectual processes are those mental operations that enable one to acquire new knowledge, apply that…

A multiple choice achievement test was constructed in which both cognitive level and degree of abstractness were controlled. Subjects were 75 students from a major university in the Southwest. A group of 13 judges, also university students, classified the concepts for degree of abstractness. Results indicated that both cognitive level and degree…

One of a series dealing with current issues affecting language arts instruction, this paper focuses on thinking skills. The paper begins by raising two issues: whether thinking skills should be taught as part of each subject area, as a separate skill, or both, and whether English and language arts teachers have a special role in the teaching of…

Intended for teachers across grade levels and disciplines, this monograph reviews research on the development of critical thinking skills and introduces a series of these skills that can be incorporated into classroom teaching. Beginning with a definition of critical thinking, the monograph contains two main sections. The first section reviews…

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…
