Developed and evaluated long cane mobility computer simulation as visual rehabilitation training device and research tool in graduate students assigned to instruction (BI) (N=10) or enhanced instruction (EI) (N=9). Found higher percentage of EI students completed simulation task. Concluded that students registered positive understanding changes,…

States that if photochemical reactions can be followed spectrophotometrically, reactivities can be estimated by evaluating data from only one curve. Studies such a system using computerized evaluation and simulation. Uses chlorocuprate(II) complexes in acetonitrile solutions for the model systems. (MVL)

Examines the use of a computer simulation program as a tool to help in the understanding of wave phenomena. After analyzing some of the main difficulties and common misconceptions about waves, features of the "Making Waves" software package are described. Figures showing a typical monitor display are presented. (YP)

Describes a microcomputer-based simulation for educating teachers in classroom planning and decision-making. The conversion of a card-based simulation to microcomputers is discussed; variables involved in preinstructional decisions, classroom objectives, and managing student behavior are described; and teachers' observed policies are compared with…

Examined is the use of the microcomputer as a tutor, for simulations of experiments, and to provide graphic interpretations of abstract concepts in the college biology setting. Discussed are computer enhanced courses being used, the software library, and the computer laboratory facility. Lists reasons for adoption of computer enhanced format. (MVL)

Studies the use of computers in elementary schools as reported by principals in a survey. Discusses the survey instrument and its topics. Reports findings on drill and practice, learning new material, simulations, and problem solving. (MVL)

Studies effectiveness of using computer simulation in a fifth grade social studies class. Concludes that a computer simulation can be used as an adjunct to teaching and that one computer may be used as effectively as many in the classroom. States that educators should use software that incorporates graphics, cuing, randomization, immediate…

Compares the effect of a chemistry computer simulation, written by the author, with the effect of an instructor demonstration. The study indicates that in this particular situation the operation of a spectrophotometer can be effectively taught by computer simulation method. The program is written using HyperTalk, the HyperCard programming…

Describes a social studies computer simulation, "SimCity," that was used to teach seventh graders in a middle school their responsibility to be informed citizens, to participate in local decision making, and to learn to work cooperatively in teams. Realism, relevance, student motivation, and future activities are discussed. (LRW)

Describes a study of undergraduates studying genetics that compared the effectiveness of a computer simulation used before and after formal instruction. Treatment of the experimental and control groups is explained, and results are reported which support the theory that the effectiveness of the simulation is dependent on the sequence of…

Describes a study of novice and advanced preservice teachers that explored the effect of a computer simulation on decision-making training for planning lessons. Treatments of the experimental and control groups are described, results of pretests and posttests are analyzed, and further research is suggested. (14 references) (LRW)

Describes a study of undergraduates at Iowa State University that tested the effectiveness of a computer simulation of electric circuits used in combination with a conceptual change approach to science instruction. Erroneous preconceptions of scientific concepts are discussed, and the use of traditional text is compared with conceptual change…

Proposes a theory of cognitive processes in doing and learning place value arithmetic. Discusses a computer model that simulates the learning of multicolumn subtraction under one-on-one tutoring to measure the relative difficulty of two methods of subtraction. The model predicts that regrouping is more difficult to learn than an alternative…

The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)
