Much of the research about using computers in testing and grading is descriptive in design. Doying, Matheny, and Minnick (1983) discussed a computerized test generation package used with a Principles of Entomology course. Tice (1981) wrote that an interactive grade recording package was effective for his agricultural economics course, but a written grade book was still needed. Meanwhile, students who voluntarily took make-up quizzes on videoscopes or typewriter consoles during a Principles of Micro-Economics course had significantly higher averages for all quizzes taken and higher final grades in the course. (Thatch, 1983).
