Tracking Information Literacy in Science Students: A Longitudinal Case Study of Skill Retention from General Chemistry to

Does early exposure to information literacy promote long-term student success? This paper describes a longitudinal case study testing the hypothesis that students who engage with scientific literature and develop information literacy early in their undergraduate studies will achieve higher grades on literature-based assignments in future coursework. We reasoned that students with previous experience in the scientific literature will develop more efficient and effective strategies to search and evaluate the literature and will ultimately favor higher-quality journals. To test these hypotheses, student performance data were collected during scientific literature-based assignments in two upper-division undergraduate lecture courses, Biochemistry 1 and Biochemistry 2. Data were analyzed from two student populations: students with prior information literacy instruction and critical practice from an Honors General Chemistry course sequence, and those students who had not undergone this training. The results indicate that, in Biochemistry 1, students with this prior information literacy training tend to use more professional, expert-like tools for exploring scientific literature and earn statistically higher scores on literature-based projects. However, by Biochemistry 2, the gaps close in both the exploration of the scientific literature and grade performance. This indicates that once students develop a foundation in information literacy, their sophistication in finding information and their performance on subsequent literature-based tasks improve. There was a small and statistically insignificant tendency for groups containing more students with prior information literacy training to cite more articles from the primary literature. However, the quality of the citations, as measured by journal impact factors, did not differ between the populations. The results of this interdisciplinary case study suggest that teaching information literacy to science students has both immediate and longlasting benefits.
