P672: Evidence for the success of a supplemental chemistry course
Students at Penn State have the option to enroll in a supplemental chemistry course offered in parallel with, and requiring a co-requisite of, Introductory General Chemistry. The efficacy of this course had not been firmly established until recently. Here, we present the findings of our analysis investigating the effect of this supplemental course on student performance. ALEKS has become a popular online learning tool and has been used as a basic skills tool at Penn State for four years. We will present the results of our statistical analysis highlighting the relationship between student scores on an initial ALEKS assessment and scores on coursework to demonstrate the predicative nature of the initial assessment. Using this initial assessment, we determine the expected performance in General Chemistry for two student groups: those enrolled only in General Chemistry and those enrolled in both General Chemistry and the supplemental course. We then compare the actual course performance for both groups to demonstrate the effect that enrollment in the supplemental course had on student performance in General Chemistry.
