Application of Computer Graphics to Graphing in Algebra and Trigonometry. Final Report.
Morris, J. Richard
This project was designed to improve the graphing competency of students in elementary algebra, intermediate algebra, and trigonometry courses at Virginia Commonwealth University. Computer graphics programs were designed using an Apple II Plus computer and implemented using Pascal. The software package is interactive and gives students control over events occurring in a lesson. The student types in answers or otherwise replies to questions, plots points, and takes quizzes at appropriate places in the lesson. The student can see graphs drawn quickly and accurately; concepts covered in the classroom are reinforced by these supplementary lessons. A list of seven available graphics lessons is given and each is briefly described: introduction to the keyboard, linear equations, what's my line (game on linear equations), inverse functions, quadratic equations, parabola game, and exponential functions. Specifications are also included for eight yet-uncoded lessons on exponential, logarithmic, and trigonometric functions. Appendices provide samples of input and output, plus abstracts of two papers on the project. (MNS)
