Describes a study which measured how ninth-grade students integrated information about mathematical concepts when working with Triple Representation Model software. Tables, graphs, and algebraic functions were linked, allowing students to manipulate several representations of the same concept. Examples of mathematical problems and student case…

This journal issue, presenting review of 1990 science education research, is divided into categories, including among others Conceptual Change and Achievement; Problem Solving; Science Process/Inquiry Skills; Cognitive Development and Logical Reasoning Skills; Assessment and Research Design; the Nature of Science; Science, Technology, and Society;…

Introduction: The Maui Hawaii Educational consortium (the Maui School District and Maui Community College) sought scientifically based evidence for the effectiveness of the Cognitive Tutor (CT) Algebra I Curriculum to inform adoption decisions. Decision makers were particularly interested in whether the use of the CT program affects achievement of…

Analyses of the cognitive activity displayed by students on existing innovative assessments in science were conducted. The project has worked with pilot alternative assessment programs in Connecticut and California to document the match or mismatch between the skills and processes that the assessment is designed to tap and those actually elicited.…

This publication contains reference materials and activities for teachers in a staff development program in New York City, teaching grades 3 and 6. The program combines content and methodology. Sections in the publication include: (1) Student Verbalization Resources; (2) Manipulative Resources; (3) Probability, Statistics, and Graph Resources; (4)…

This research paper describes the use of computer mediated conferencing (CMC) to support the teaching of biology to undergraduates. The use of this pedagogical innovation was a first-time experience for both the instructor and his students. The objectives of this project were to increase students' active participation, to facilitate collaborative…

THE CONTRIBUTIONS OF 21 AUTHORS IN THIS VOLUME ARE DEVOTED TO ASSESSING THE STATUS OF RESEARCH AND THEORY IN MENTAL DEFICIENCY, FOCUSING ATTENTION ON THE BEHAVIOR OF THE MENTALLY HANDICAPPED. PART ONE IS CONCERNED WITH RESEARCH FINDINGS AND THEORIES TO EXPLAIN MENTAL DEFICIENCY. COMPREHENSIVE PSYCHOLOGICAL THEORIES REPRESENTED INCLUDE FIELD…

This longitudinal study investigated the ways in which two groups of eight students used spreadsheets to represent and solve algebra problems and related this to their previous arithmetical experiences and evolving use of symbolic language. The spreadsheet environment supported students to move from specific to general thinking. Includes story…

Teaching is a complex act requiring expertise relative to content, students, and the myriad of alternatives available to bring the two together in meaningful ways. This monograph is designed to assist teachers in examining and altering their own teaching practices and in transforming the classroom from a place of "dull sameness" to an…

This paper examines a range of studies done on the "Geometric Supposer" software and its use since the mid-1980s. It describes how the "Geometric Supposer" is a response to the call for reform by the mathematics community to create classroom environments that allow students to construct their own knowledge. This approach to…

Abstracts of most of the papers, symposia, and poster sessions presented at the 60th conference of the National Association for Research in Science Teaching (NARST) are provided. Subject areas addressed include: videodisc technology; problem solving; cognitive learning; attitudes toward science; teaching strategies; science, technology, society;…

INCLUDED ARE SELECTED ARTICLES FROM "SCIENCE AND CHILDREN" COVERING THE PERIOD SEPTEMBER 1963 THROUGH MAY 1966. THE SELECTION CRITERIA WERE THAT THE ARTICLES (1) PRESENT MATERIAL WHICH IS CONSISTENT WITH ACCEPTED PHILOSOPHY AND PRACTICES AND WITH THE LATEST TRENDS IN SCIENCE EDUCATION, AND (2) PROVIDE USABLE MATERIAL FOR CLASSROOM TEACHERS,…

For this study, the second in the cross sectional series, based on the Conceptual Learning and Development (CLD) model, assessment batteries were developed to determine each child's level of attainment and related use of the concepts "equilateral triangle,""cutting tool,""noun," and "tree." Batteries were…

For this study, the second in the cross sectional series, based on the Conceptual Learning and Development (CLD) model, assessment batteries were developed to determine each child's level of concept attainment and also the related use of the concepts "equilateral triangle,""cutting tool,""noun," and "tree."…

This study examined the effects of an inductive multimedia program, including graphs, on subjects' ability to create linear functions and conceptualize variables from word problems. Subjects were 98 undergraduate students in two sections of a computer literacy course. Students' achievements were assessed via pre- and posttests, which were parallel…
