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)

Presents the geometric, software-ergonomic, and educative standards for interactive graphics systems envisioned for planimetric constructions and calculations in secondary mathematics instruction. Describes the geometric-didactic potentials of the MS DOS-Version 1.6 of CABRI-Gomtre which is an Intelligent Tutoring System with the possibilities for…

Describes the method for producing the equiangular spiral, the geometric curve generated by modeling an insect's orientation process to an illumination source, utilizing a LOGO Turtle program which is included. (JJK)

Described is the use of computer software, with and without guiding text, for a simulation that presents processes related to electric charges and electric forces underlying the electric-pendulum phenomenon. Included are methods for integrating this simulation with actual middle-school science class demonstration. (JJK)

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)

Reported is an approach to teaching the use of Macintosh computers to sixth, seventh, and eighth grade students within the context of a simplified model of scientific research including proposal, data collection and analyses, and presentation of findings. Word processing, graphing, statistical, painting, and poster software were sequentially…

Reviews three computer software: (1) "Elastic Lines: The Electronic Geoboard" on elementary geometry; (2) "Wildlife Adventures: Whales" on environmental science; and (3) "What Do You Do with a Broken Calculator?" on computation and problem solving. Summarizes the descriptions, strengths and weaknesses, and…
