A study was conducted at Donnelly College, in Kansas, to determine whether taking a math course prerequisite affected students' final course grades in an introductory chemistry course. From a sample of 329 students who finished the chemistry course between fall 1985 and fall 1993, course grades were compared for 30 students who had completed the math prerequisite and 30 who had not. Study results indicated that the math prerequisite course was not a significant predictor of higher course grades in the introductory chemistry course. Although the samples used in the study were randomly obtained, the small sample size may have provided unwarranted conclusions. Recommendations from the study include the following: (1) the study should be reviewed by the math and science department administration; (2) the math and science administration should discuss other findings from the literature relative to prerequisite courses, specifically in science education; (3) the study should be replicated; (4) the results should be reviewed by other departments; and (5) a college-wide committee should be established to review the research findings in order to issue a set of recommendations and guidelines on prerequisites and other curricula matters.
