Using the California Chemistry Diagnostic Test and Other Student Background Factors To Predict Grades and Success in General Chemistry I.
Georgakakos, John H.
A study was undertaken at California's Riverside Community College District to determine predictors of grades and success rates in a first-semester general chemistry course. Fall 1996 course outcomes were analyzed for two groups of students: 137 who had completed the course, successfully or not, and 178 who had dropped it. Data were also collected for the sample from results of the California Chemistry Diagnostic Test (CCDT) and a pretest survey, both administered on the second day of the semester, and District records of students' grades and characteristics. From these data, 19 independent variables were identified and a regression analysis was run to determine which factors were associated with student success. The analysis indicated that grades were predicted by a 4-variable model including students' cumulative college grade point average (GPA), CCDT score, "B" or better grades received in advanced science and mathematics courses at high school, and Asian ethnicity. Course success was found to be related to college GPA; CCDT score; receiving a "B" or better in preparatory chemistry; and "B" or better grades in high school algebra, geometry, and biology. Appendixes provide the pretest instrument; a list of independent variables; and discussions of data techniques related to missing values, frequencies, variable reduction and screening, correlations and basic statistics, analysis of models, and comparisons of general chemistry results. Contains 42 references and 16 tables and figures. (HAA)
