Phase changes in water are experienced in everyday life but students often struggle to understand mechanisms that regulate them. Human thermal comfort is closely related to humidity, evaporative heat loss and heat transfer. The purpose of the present study is to assist students in the evaluation of human thermal comfort. Such a goal is achievable…

This paper reports the findings of a study of student attitudes and student improvement in conceptual understanding using conceptests with an electronic response system in lecture courses. Students and instructors valued the feedback and interaction that the response system afforded. For a majority of the chemistry topics studied, student…

The dual purpose of this article is to provide a synthesis of the findings related to the use of computer simulations in physics education and to present implications for teachers and researchers in science education. We try to establish a conceptual framework for the utilization of computer simulations as a tool for learning and instruction in…

Presents a study using an electronic bulletin board as the software platform for students in a large second-year college biology course to improve communications among students and between students and the instructor. Reports that the bulletin board was successful in fostering interaction between students as well as improving student-instructor…

Described is a series of five related microcomputer-based laboratory analysis programs that are used by students in a college calculus-based physics course. With minor modifications these programs, which are written in BASIC, could be used in most beginning undergraduate laboratory science courses. (RH)

Described is a microcomputer software program NUCLEAR REACTIONS designed for college level students and in use at Sweet Briar College (Sweet Briar, VA). The program is written in Microsoft Basic Version 2.1 for the Apple Macintosh Microcomputer. It introduces two conservation principles: (1) conservation of charge; and (2) conservation of nucleon…

Described is a Monte-Carlo method for modeling physical systems with a computer. Also discussed are ways to incorporate Monte-Carlo simulation techniques for introductory science and mathematics teaching and also for enriching computer and simulation courses. (RH)

Resistance probes for the laboratory can be divided into two main categories: (1) those involving direct use of resistance; and (2) those involving an indirect use of resistance. Described are several applications of both types related to chemistry and physics. (RH)

Decribes a study which compared computer assisted instruction (CAI) with a parallel paper-and-pencil module to assess the impact on students' achievement and attitudes in chemistry. Supports the contention that CAI works as well or better than more traditional methods and tends to promote positive attitudes. (RT)

Explains the use of the 3-dimensional analytic geometry method to find values for a field geology problem. Gives a description of the mathematical theory for this method which can be applied to data obtained by drilling as well as open surfaces, and a computer program. (RT)

Provides abstracts of selected mathematics and science papers presented during the conference. Topics included: (1) problem solving using the computer; (2) controlling the environment through Logo; (3) software and technology in the science curriculum; (4) learning multiplication facts using multiple strategies; and (5) limitations and potential…

Discusses three types of sensors; pressure, gas detection, and relative humidity. Explains their use for laboratory measurements of gas pressure and detection of specific gaseous species. Shows diagrams of devices and circuits along with examples and applications including microcomputer interfacing. (RT)

Provides an annotated list of references on computer-oriented projects. Includes information on computers; hands-on versus simulations; games; instruction; students' attitudes and learning styles; artificial intelligence; tutoring; and application of spreadsheets. (RT)

Details a rationale for teacher shared information. Outlines possible content to include in such a network. Describes advantages and implications a database might have for teachers. (RT)

Discusses why, when and how microcomputer simulations of biological topics should be used in the classroom. Includes a five-step procedure for creating such simulations using population growth as an example to describe each step. Steps include topic/background material selection, writing program, and making support materials for the simulation.…
