The effects of two methods of testing students on student grades were studied in 1982 with two economics classes that were taught by the same instructor. One class, which involved four 1-hour lectures weekly, received the normal four block-form examinations. The 34 students in this class were the control group. The 36 students in the other class received eight quizzes over smaller amounts of material. End of course grades, pre-test scores, and post-test results were compared at the end of the semester. The study was conducted because business and economics faculty were concerned about low student achievement in all economics classes at Fayetteville Technical Institute. Results showed that both evaluation methods were equally successful with respect to course grades. It is recommended that: course objectives be written; students' attitudes toward the evaluation methods used in economics classes be determined; and that the study be replicated. (Author/SW)
