A number of studies in science education have indicated the general effectiveness of level one videodisc-based programs in improving student knowledge in the sciences. The purpose of the evaluation study was to ascertain the effectiveness of the videodisc-based elementary science program in selected K-6 grade classrooms as determined by the users…

The effect of mode of computer-assisted instruction (CAI) and individual learning differences on the learning of science concepts was investigated. University elementary education majors learned about home energy use from either a computer simulation or a computer tutorial. Learning of science concepts was measured using achievement and…

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)

Summarizes the sources, statistical methods, and general findings from the review. Poses findings on specific questions of research. Gives implications of past research for the future. (MVL)

The purpose of this study was to determine whether an electronic geoboard, a computer-software program, could be used to assess youngsters' ability to discover facts and relationships in an unlabled and ambiguous situation. Subjects--108 children, ages 6 to 12--were enrolled in grades 1 to 6 in Norwood, New York. The electronic geoboard served as…

Turtle graphics is a popular vehicle for introducing children to computer programming. Children combine simple graphic commands to get a display screen cursor (called a turtle) to draw designs on the screen. The purpose of this study was to examine young children's abilities to function in a simple computer programming environment. Four- and…

This research project was designed to evaluate the synergistic effects of linking workshops for science teachers with electronic conferencing. The rationale for this study was that these two methods of professional development and communication would have an impact beyond that which either would have alone. Included are the abstract, a description…

This study investigated the attention or arousal of above and below average boys and girls while viewing a science television program on videotape. Skin resistance (GSR) was measured by a biosensor attached to a microcomputer and served as the dependent variable. Analysis of the data included a 2x2x8 ANOVA of gender v. ability v. GSR. The…

There are a number of ways in which the educational applications of computers can be categorized. This document focuses on the use of computers in science teaching. It differentiates between such terminology as tutor, tool, tutee, tutorial dialogue, revelatory use, conjectural use, and emancipatory use. The major portion of this paper is a…

Reports on a study designed to analyze six primary science education journals published in 1985 and compares the results with some baseline data collected in 1970. Results indicated that the amount of material being published per year during that period increased, with additional emphasis on methods of teaching. (TW)

Describes and evaluates science teachers' implementation of microcomputers at a field-test site that was part of a program to encourage literacy of science teachers in the use of microcomputers (ENLIST-Micros). Discusses why only 33 percent of the teachers used computers one year after the training. (Author/YP)

Because density is unobservable and must be inferred from knowledge about weight and size, it is a difficult concept to teach and learn. Even after traditional instruction, many students still have an undifferentiated concept that mixes characteristics of both weight and density. In this study, researchers tested the effectiveness of a unit they…

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…

Discusses the importance of the use of models in modern science. Suggests that models can make a significant contribution to the teaching of science and mathematics. Explains that representative models, analogue models, logical models, and theoretical models are most commonly used models in science and mathematics. (TW)

Many feel that an advantage to using computer simulations in science teaching is that they give students the opportunity to witness or perform experiments which might otherwise be too expensive, time consuming, or dangerous for them to do. Simulations attempt to mimic the kind of experience students get in a laboratory and help students learn new…
