Reports on the development and application of a series of computer programs which simulate the outcomes of students' perceptions regarding forces acting on objects at rest or in motion. This dissonance-based strategy for achieving conceptual change uses an arrow-based vector language to enable students to express their conceptual understanding.…

The results of a simulation model of a queuing system are reported. Use in an introductory quantitative analysis course to enhance students' computer and quantitative modeling knowledge is described. (CW)

An experimental class in introductory statistics (n=40) using simulation software at American University was compared to a traditionally taught control group (n=36) with respect to achievement and accrued beliefs about the benefits of the simulations. Results indicate significantly higher achievement scores for the experimental class with about…

Explores the application of the microcomputer as an adjunct to laboratory experiments within the science curriculum. Identifies needs and critical competitors that may affect implementation. Indicates problems along with suggestions for improving the effectiveness of this method. (RT)
