High risk students in college chemistry are often identified by low mathematics SAT scores, low American Chemical Society Toledo scores, and secondary school chemistry grades. This study was designed to identify additional variables that can be used at the community college level as predictors of success in chemistry. The study compared students' mid-semester and final grades in two levels of general chemistry with: (1) their level of intellectual development; (2) attainment of science process goals; (3) background in laboratory science, chemistry, physics and algebra; (4) attitudes toward science, mathematics and chemistry; (5) grade expectancy; (6) cognitive style; (7) sex; and (8) age. Of the predictors of success identified for the introductory chemistry class, the best predictors were grade point average (GPA) and prior chemistry background. The successful student in introductory chemistry was older, had a better grasp of science process skills, and had good algebra grades. The analysis identified 13 predictors of success in the general chemistry courses; the single best predictor for success was GPA. High scores on the Test of Logical Thinking (TOLT) and the Test of Integrated Process Skills (TIPS) were also significant predictors. (TW)
