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.

The essays collected in this volume are concerned with the field of computer-based intelligent instruction. The papers are organized into four groups that address the following topics: particular theoretical approaches (3 titles); the development and improvement of tools and environments (3 titles); the power of well-engineered implementations and…

Three purposes of this study were to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for high school physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this…

This paper illustrates a model of the layperson's reasoning patterns under conditions of uncertainty, the "outcome approach," which was developed from analysis of videotaped problem-solving interviews with 16 undergraduate students. According to the outcome approach, the goal in questions of uncertainty is to predict the outcome of an…

Focusing on the role of language in learning, this paper discusses schemata and symbolic thinking that help students learn from unfamiliar experiences. The first part of the paper introduces the idea of symbolic thinking by comparing students encountering new ideas with convention-goers making their way around a new city. The section suggests that…

Reports on a study using 126 university freshmen to examine the effects of instruction and practice in a discourse structure reading and writing strategy focusing on main ideas, supporting ideas, and central ideas. Indicates the discourse structure treatment is effective and worthy of further study. (NH)

Shows the effects of a tutorial program for college students using process-oriented instruction. Process-oriented instruction combines domain-specific knowledge with teaching thinking strategies. Tutorials included a diagnostic learning style instrument and learning guides. Evaluation questionnaires and exam scores both indicated improved study…

Points out a misconception that is reinforced in many elementary and advanced chemistry texts. Discusses the general limitations of the orbital concept. Notes misconceptions related to the transition elements and their first ionization energies. (MVL)

Principles of W. Kintsch's reading comprehension model (1978, 1980) were used to revise an expository text. Two experiments with 170 undergraduates and 125 Air Force recruits indicated that the principled revision conveyed the author's intentions better than the original text, suggesting the model's use for text improvement. (SLD)

Examines two different types of human motivation, pragmatic and nonpragmatic. Experimental studies in preschool-age children in both the former Soviet Union and Western cultures are presented. Suggests that the two contrasting conceptions of human motivation lead to totally different practical strategies for transforming human motivation in…

Learning differences or disabilities can be best understood and addressed within the holistic/constructivist theory of knowledge construction and the reciprocal evolution of cognitive structures. Learning differences manifest themselves in the spirals of mental structuring activity that guide relational thinking. Such a perspective focuses on…

This paper discusses the central thesis that new research on estimation and mental computation will benefit from more focused attention on the situations in which they are used. In the first section of the paper, a brief discussion of cognitive theory, with special attention to the emerging notion of situated cognition is presented. Three sources…

A powerful way of understanding something new is by analogy with something already known. An analogy is defined as a mapping from one structure, which is already known (the base or source), to another structure that is to be inferred or discovered (the target). The research community has given considerable attention to analogical reasoning in the…

One of the most common misconceptions about probability is the belief that successive outcomes of a random process are not independent. This belief has been dubbed the "gambler's fallacy". The belief that non-normative expectations such as the gambler's fallacy are widely held has inspired probability and statistics instruction that attempts to…

This study develops and employs the construct, personal orientation to science learning, to study the processes by which children construct meaning as they learn science in school. The theoretical bases of the thesis are the commitments of a constructivist view of learning and the psychological framework of George Kelly's Personal Construct…
