An analysis of some factors affecting student academic performance in an introductory biochemistry course at the University of the West Indies


high failure rates
introductory biochemistry
learning preferences
mature students
entry qualifications


High failure rates at tertiary institutions result in unacceptable levels of attrition, reduced graduate throughput and increased cost of training a nation's labour force. It is imperative that diagnostic studies are carried out to identify the major factors that are associated with suboptimal academic performance with a view of instituting corrective measures. This study was, therefore, designed to identify and analyse some determinants of academic performance (as measured by coursework exam grades) in an introductory biochemistry (AGRI 1013) course plagued by chronic high failure rates. The course is offered to first year undergraduate students in the Faculty of Science and Agriculture at the University of the West Indies, St. Augustine campus. A survey instrument was administered to a random sample of 66 registered students of AGRI 1013 (representing a 40% sampling fraction) to generate data on demographics (gender and age), learning preference, and entry qualifications. The effect of learning preference, age, gender, and entry qualifications on academic performance (measured as the final coursework mark obtained) was determined. Relationships/associations between gender and learning styles, gender and entry qualifications, age and learning preferences, and age and entry qualifications were analyzed using Pearson's chi-square test. There were significant (P < 0.05) associations between entry qualifications and both gender and age. However, since entry qualifications did not significantly (P > 0.05) affect academic performance, this association should be of limited concern. None of the investigated factors significantly affected academic performance. This observation could be a consequence of an impressive performance in the coursework exams by a large proportion of students resulting in less variation in the recorded grades. Learning preferences were found to be independent of both the age and gender of students. It was concluded that more determinants of academic performance need to be investigated and that students who are admitted based on a diploma in agriculture may need a remedial course given that their coursework grades, though statistically insignificant were consistently lower than that of the other students.
