The first report of an ongoing case study examining the impact of using a laboratory of microcomputers as a tool for teaching science and social science courses in a high school, this paper reports on a sociological investigation of the organizational change in the structure and functioning of the school brought about by the introduction of the…

This paper reported the results of a study designed to determine whether certain instructional strategies are superior to others in teaching problem solving to high school chemistry students. The effectiveness of four instructional strategies for teaching problem solving to students of various proportional reasoning ability, verbal and visual…

Presented is a study of eighth-grade students' academic problem-solving ability based on their knowledge structures, or their information stored in semantic or long-term memory. The authors describe a technique that they developed to probe knowledge structures with an extension of the card-sort method. The method, known as the Concept Structure…

States that students who simultaneously acquire subject matter concepts and high-level thinking skills are more likely to learn, remember, and be able to apply the concepts. Provides an example for assisting faculty in developing better decision-makers. (RT)

Summarizes current developments in alternative frameworks research in science education. Covers concept maps, learning as conceptual change, classroom strategies, problem solving in physics and where research should be going. (CW)

Explains how a Forensic Science and Criminology unit can help in the development of science process skills, mastery of laboratory techniques, and assist in value clarification. Examples of investigations and activities that have been successful with fifth- and sixth-grade students are included. (ML)

Describes a computer program written in Microsoft BASIC for use on personal computers to calculate travel times of refracted waves in layered structures with arbitrary dipping interfaces. Exercises for student use are given to illustrate some of the basic properties of reversed refraction travel time graphs. (TW)

Discusses the results of a study on the limitations of short-term memory in terms of its implications for the teaching of chemistry and problem-solving skills. Also includes a description of the Saskatchewan life skills program for disadvantaged adults for coping with change. (ML)

Compared "extended discretion" (ED) learning approach to traditional Biological Sciences Curriculum Study (BSCS) laboratory investigations. Found that although ED students are more capable of exercising independent judgment for greater lengths of time while BSCS demanded more teacher time, all teachers were still reluctant to accord…

Some applications of ratio and proportion to scale drawing involving geometric figures are given. The activities or problems concern the earth and space, scale speeds, and the earth-moon system. (MNS)

The purpose of this research was to describe how self-efficacy affects the development and science achievement of practicing teachers after their participation in a half day long hands-on science lesson provided by the Science on Wheels project. The 42 practicing K-8 teachers were from eight different counties located in a rural mid-eastern state.…

This study investigates the fate of claims made by middle school science students working in collaborative groups in a multicultural urban classroom and the concomitant effects on engagement and understanding. Given problems of a complex and open-ended nature in a learning community setting, students were challenged to establish group positions…

This volume is the flagship volume in a series on cognitive strategy instruction. While strategies instruction is particularly appropriate for the learning disabled, it is also very useful for normal learners, especially inner city and minority children. The series focuses on conveying strategies instruction methods for use with these children.…

This document contains two volumes of papers presented at the first annual meeting of the International Organization of Science and Technology Education Symposium. Each volume of papers is divided into two sections. Section 1 of the first volume focuses on relevant teaching, incorporating curriculum, teaching approaches, and assessment aspects.…

This report documents a program for improving science knowledge, attitudes, and higher order thinking skills through experiential science. The hands-on approach used successfully in the program is described, and evidence of student improvement is also presented. The targeted population consisted of students in the first, third, and fourth grades…
