Presented are system concepts with examples of various vendor approaches for implementing laboratory local area networks. (CW)

The purpose of this paper is to describe the development of both the instrumentation and the software of an emerging, high-technology system used for science instruction. A marriage of computer and television technologies has evolved into an exciting new learning system called interactive videodisc instruction. The development of the hardware…

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…

Described is a mineral identification program which uses a shell system for creating expert systems of a classification nature. Discusses identification of minerals in hand specimens, thin sections, and polished sections of rocks. (Author/CW)

Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)

Research indicates that the educational effectiveness of Microcomputer-Based Laboratories (MBL) may be due to the real time nature of the experience. This article describes a study where kinesthetic feedback was completely removed by giving students only visual replications of a motion situation. If simultaneity of perception is the important…

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…

A series of computer-based activities were integrated into the laboratory portion of a two-semester university biology course for elementary teaching majors. The purpose of the project was to address the biology instruction provided to the students while at the same time providing examples of appropriate uses of computers in instruction,…

Describes a deterministic computer model that incorporates: (1) initial framework composition; (2) abrasion factors for quartz, feldspar, and rock fragments; and (3) a fragmentation ratio for rock fragments to simulate the recycling of coastal sands by rivers and beaches. (TW)

Described is the use of Thematic Mapper images in undergraduate geology instruction. The work of the Andes Project at Cornell University is discussed. Digitally enhanced illustrations of landforms in the Andes mountains of South America are provided. (CW)

Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

This paper reports on the effects of structuring problem solving activities of novices in the domain of physics in a way consistent with the problem solving approaches used by experts. A total of 42 undergraduate students who completed a first semester physics course and received a grade of B or better participated in this study. The treatment…

This article presents a vector-analysis approach to the classical three-point problem in hydrogeology. Problem sets involving strike and dip, and ground water flow including computer programs (in BASIC) for their solution are given. (CW)

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)
