Presents a framework identifying the molecular level assumptions underlying many thermodynamic models. Tests the assumptions using theory and computer simulation to develop better assumptions. (YP)

Described are analytical applications of the theory of random processes, in particular solutions obtained by using statistical procedures known as Monte Carlo techniques. Supercomputer simulations, sampling, integration, ensemble, annealing, and explicit simulation are discussed. (CW)

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

The third workshop on marine ecosystem modeling is one in a sequence of activities designed to promote modeling as a research and management tool among Mediterranean marine scientists. Previous workshops served mainly as a forum for a familiarization with modeling, while this workshop focused on specific implementation of modeling technology. The…

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…

An integral part of the curriculum in introductory biology courses is the study of Mendelian genetics. Results from genetics learning studies and needs assessments demonstrated the need for additional intensive research in biology education and genetics learning. There exists a lack of detailed information describing reasoning patterns and…

This study used a microcomputer program which diagnosed and remediated an alternative conception of velocity. Results show computer simulations are credible representations of reality and that the remedial part of the program produces significant conceptual changes in students holding the alternative conception.

A cadre of thinkers called cognitive scientists has been investigating some of the same issues that first possessed the Greeks. As did the Greeks, they seek to understand what is known, ponder the sources of knowledge, conjecture about the various vehicles of knowledge, reflect on language, and speculate on the nature of the activity of knowing.…

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)

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)

Describes five computer software packages; four for MS-DOS Systems and one for Apple II. Included are SPEC20, an interactive simulation of a Bausch and Lomb Spectronic-20; a database for laboratory chemicals and programs for visualizing Boltzmann-like distributions, orbital plot for the hydrogen atom and molecular orbital theory. (CW)

Discusses some of the contributions that high-speed computing is making to the study of science. Emphasizes the use of computers in exploring complicated systems without the simplification required in traditional methods of observation and experimentation. Provides examples of computer assisted investigations in astronomy and physics. (TW)

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)

Reports on a study which was designed to determine if computer assisted instruction (CAI) can be used effectively in biochemical education. Results indicate that CAI in the drill and practice mode and computer simulations had no detrimental effect on the students' academic achievement and the students would like more CAI. (TW)

A simulation game was used in an attempt to change undergraduates' behavior and attitudes toward energy conservation. Social influence was found to be correlated significantly with experimental treatment. Participants showed an increase in favorable attitudes toward activism and political efficacy, and exhibited a greater likelihood of taking…
