This research is framed within the analysis of the evaluation methodology in General Chemistry at the School of Chemistry of the University of Costa Rica (UCR). The General Chemistry program at the UCR serves approximately 2 000 students per semester, mostly STEM majors. Courses include the traditional General Chemistry 1 and 2 sequence in addition to a fast-paced Intensive General Chemistry course that combines contents from the sequence in a single semester. Section enrollment ranges from 90-150 students. Passing rate across the program averages around 60% although in individual sections it may be as low as 35%. Current program efforts intend to identify and correct possible sources of student failure. Exams are the sole base of course grade and based exclusively on multiple-choice items. This study investigates student perception of the evaluation system and how it may influence the teaching-learning process. It also explores the pedagogical reasons that weigh on faculty decisions in relation to the assessment methodology. The ultimate goal of this project is to catalyze reflection and promote overall improvement of the process of teaching and learning. This talk will also present general aspects of post-secondary chemistry education in Costa Rica.
