Describes the development, use, and evaluation of the "Osmosis Program" as a teaching tool to elicit and challenge college students' understanding about diffusion and osmosis. Results showed students using the program performed better on a diffusion and osmosis assessment test than students not using the program. (Author/MKR)

This article utilizes several examples to describe the use of MathCAD, a computer scratchpad for calculations, within a lecture-demonstration method of teaching general calculus. Both hardware requirements and software features are discussed specifically related to the proper design of student worksheets with emphasis on parameter variation. (JJK)

Examples of subroutines that generate both symbolic and graphic solutions to differential equations are presented for the two computer algebra systems, MAPLE and Mathematica. Included are the listings for the Mathematica procedures developed for use in this article. (JJK)

Describes several exemplars of software that emulate and incorporate machine-supported aspects of cognitive apprenticeships in science and mathematics. Concludes with an evaluation of software against cognitively guided principles and with a summary of the difficulties associated with creating and implementing machine-supported apprenticeships.…

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…

Described is the application of microcomputers to predict reaction rates based on theoretical atomic and molecular properties taught in undergraduate physical chemistry. Listed is the BASIC program which computes the partition functions for any specific bimolecular reactants. These functions are then used to calculate the pre-exponential factor of…

Examines the strengths and weaknesses of five selected statistical software packages with respect to how well the software enhances business statistics instructors's ability to teach traditionally difficult topics. Ranks the software on technical and pedagogical benefits. Results indicate (1) no advantage to using textbook-related software over…

Described is a weekly computer algebra laboratory course for Calculus I students during the 10-week spring semester, 1990, at Trinity University. Advice on the establishment and management of this type of laboratory including descriptions of student participation trends and student reactions is presented. (JJK)
