Described is a computer tutor designed to help students gain a qualitative understanding of important physics concepts. The tutor simulates a teaching strategy called "bridging analogies" that previous research has demonstrated to be successful in one-on-one tutoring and written explanation studies. The strategy is designed to remedy…

Describes an interactive computer program (RelLab) that acts to introduce the fundamental ideas of relativity to students. Students working cooperatively investigate paradoxes of relative motion by constructing thought experiments and discussing their findings. (ZWH)

Problem solving is an essential skill in the study of genetics. Genetics problems have traditionally come from laboratory activities and textbook situations. Recently computer-based problems have been available to complement these standard sources. This report focusses on the use of computer-based problems in the study of genetics. Discriptions…

Describes attempts to instruct 12 children, aged between 10 and 11, during a 12-hour course in LOGO that proper attention should be paid to the external angles through which the turtle rotated. Results suggest that using LOGO to draw closed figures may lead to confusions about angle that are not amenable to conventional intervention techniques…

Examines the use of a computer simulation program as a tool to help in the understanding of wave phenomena. After analyzing some of the main difficulties and common misconceptions about waves, features of the "Making Waves" software package are described. Figures showing a typical monitor display are presented. (YP)

This paper describes the characterization of a student's framework of heat and temperature, and the development of a microcomputer-based laboratories (MBL) intervention program for grade 9 and grade ll students. The report presents the results of classroom study, including interview questions and answers and pretest/posttest, from experimental and…

This investigation focuses upon the question of: (1) how naive subjects organize and represent knowledge when solving problems; (2) how previous experience of a novice is used in solving a problem; (3) what kinds of information and knowledge are sought as well as overlooked by novices when solving problems; (4) what kinds of strategies novices…

Trying to change the predictive rule for the sinking and floating phenomena, students have a great difficulty in understanding density and they are insensitive to empirical counter-examples designed to challenge their own rule. The purpose of this study is to examine the process whereby students from sixth and seventh grades relinquish their…

Points out two areas of difficulty in teaching Newtonian dynamics. Describes several alternatives to physics learning using new technology. Details the use of the LOGO computer language in teaching simple Newtonian environments. Suggests the potential for creating new learning experiences in dynamics with new technology. (CW)

Reviews and analyzes research related to the teaching and learning of science completed in 1985. Includes: (1) reviews of research; (2) evaluation; (3) student characteristics; (4) attitudes toward science; (5) conceptual reasoning; (6) instructional treatments; (7) cognitive skills; (8) laboratory work; (9) microcomputer applications; (10)…

Describes the use of a microcomputer-based laboratory (MBL) in teaching the concepts of heat and temperature to eighth grade students. Discusses the advantages of being able to instantly display the results of their experimentation with the use of temperature and light probes, and heat pulsors. (TW)

Two classroom studies, one conducted in the spring of 1985 and the second in the spring of 1986, showed that many high school students do not differentiate between heat and temperature; instead, they have a single concept that contains some of the features of heat and some of the features of temperature. Because the distinction between these two…

The concept of the density of a material has an important role in elementary and secondary school science curricula, but it is a difficult concept to grasp. This project explores why this should be and whether there are some simpler, more accessible notions which can serve as the basis for building a concept of density in students' minds during…

This review of research in science education consists of 432 reports published in 1985. Data sources include science education journals that regularly appear in the "Current Index to Journals in Education," reports entered into the ERIC system in "Resources in Education," and dissertations reported in "Dissertation…

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;…
