When one encounters a problem that one has no adequate way of representing, a new mental model for the problem may have to be found. When a possible model is found, an important next step is to evaluate the validity of the model. In this document, examples of subjects finding and evaluating mental models used as problem representations are…

This report enumerates the activities of the Educational Technology Center (ETC) during 1987. The guide's theme for the year was Teaching with Technology. The report includes brief descriptions of five different types of research projects by area. In science education, the projects concerned with weight and density, heat and temperature, and the…

The first Earth Day was held on April 22, 1970. This monograph is an attempt to analyze the environmental improvement efforts since that time, with emphasis on environmental education and environmental studies. It is claimed that environmental policies developed over the past 17 years have failed to incorporate adequately the human dimension in…

Higher order thinking skills are inevitably developed or exercised relative to some discipline. The discipline may be formal or informal, may or may not be represented in a school curriculum, or relate to a wide variety of domains. Moreover, the development or exercise of thinking skills may take place at differing levels of generality. This paper…

The 21 essays in this two-part book provide conceptual and operational understanding of the nature of models as representations of reality and as tools for description, analysis, interpretation, and forecasting. Topic areas addressed in part 1 (concept) include: the nature of models; the earth as a system; the determination of form; some…

The problem-solving mode of teaching science implies change for teachers, administrators, state education departments, and other individuals charged with implementing educational innovation. This study provides a descriptive record and interpretation of the words and actions of an elementary school teacher beginning to learn about teaching science…

This document contains 53 plenary and contributed papers presented at the eighth Psychology of Mathematics Education (PME) meeting. Two plenary addresses focused on mathematics research in Australia and Japan, and problem solving and symbolism. Contributed papers were classified under 13 headings including: teaching and learning theory; cognition;…

This is a narrative review of research in mathematics education reported during 1987. The purpose of this review is to extract from research reports ideas that may prove useful to school practitioners. Major sections are: (1) "Planning for Instruction" (relating historical developments, aides and grades, teaching approaches, problem…

This report describes a computer-based instructional system, the Story Problem Solver (SPS). SPS provides students with instruction about the semantic structure of story problems. It was developed to test a specific schema theory of knowledge organization in long-term memory. For this reason SPS depends explicitly upon a theory of the relationship…

This research compared the performance of ninth grade females and males on flight protocol, with particular attention to interpretation of the graphs of paths of falling bodies, rolling objects, and projectiles. These subjects were chosen because they had received no formal instruction in projectile motion, yet through typical life experience, had…

Designed to help understand the cognitive and social effects of children's classroom experiences with LOGO and computers, this study presents an account of the ways in which two elementary school teachers thought about, grappled with, and practiced LOGO in their classrooms over a 2-year period. The account is organized chronologically, first…

Abstracts and abstractors' critiques of nine published research reports related to problem solving, elementary school science, science process skills, and curriculum and instruction are presented. Aspects addressed in the studies include: (1) problem-solving skills of high school chemistry students; (2) spatial puzzles and the assessment of…

This issue contains abstracts and critical comments for ten mathematics education journal articles, plus an editorial on teacher education needs by Thomas J. Cooney. Two articles focus on problem solving; the remainder concern instruction about and with computers, geometric perceptions, preservice teachers' conceptions of volume, attitudes toward…

A conceptual model is presented for the development of thinking skills by using an instructional model employing high level cognitive demands. "Distancing" is proposed as the concept to denote behaviors or events that separate the child cognitively from the immediate behavioral environment. Forms and functions of distancing behavior are…

Contains an annotated bibliography of articles which deal with computer-assisted testing. Includes the author's name, the periodical in which the article appeared, and a short description of the article. (TW)
