Objective: In educating students in the health professions about evidence-based practice, instructors and librarians typically use the patient, intervention, comparison, outcome (PICO) framework for asking clinical questions. A recent study proposed an alternative framework for the rehabilitation professions. The present study investigated the effectiveness of teaching the alternative framework in an educational setting.Methods: A randomized controlled trial was conducted with students in occupational therapy (OT) and physical therapy (PT) to determine if the alternative framework for asking clinical questions was effective for identifying information needs and searching the literature. Participants were randomly allocated to a control or experimental group to receive ninety minutes of information literacy instruction from a librarian about formulating clinical questions and searching the literature using MEDLINE. The control group received instruction that included the PICO question framework, and the experimental group received instruction that included the alternative framework.Results: There were no significant differences in search performance or search skills (strategy and clinical question formulation) between the two groups. Both the control and experimental groups demonstrated a modest but significant increase in information literacy self-efficacy after the instruction; however, there was no difference between the two groups.Conclusion: When taught in an information literacy session, the new, alternative framework is as effective as PICO when assessing OT and PT students’ searching skills. Librarian-led workshops using either question formulation framework led to an increase in information literacy self-efficacy post-instruction.

This article reports on research investigating the experiences and resources that make science thinkable for undergraduate science majors as they engage in postsecondary science contexts. We regard these experiences and resources as contributing to science majors' science capital, and we suggest that science capital accumulates over time across identity trajectories. Using a multiple case study approach, we characterize seven undergraduate science majors' identity trajectories that they narrate through their stories of experiences with science in school, out of school and into postsecondary education. We examine how they navigate sources of science capital (e.g., families, science outreach), and the value they attribute to their science capital once they enter science programs in university. We also consider how their access to science capital influences their reasons for engaging in science outreach. To characterize students' movements into postsecondary education, and their experiences in postsecondary science, we crafted three identity trajectories: the “expected trajectory,” “persistent trajectory” and the “new directions trajectory.” These trajectories helped us to examine how science majors' identities mediate their perceptions of the use and exchange values of their science capital and the doxa of science that they legitimate. This study contributes to our understanding of how science capital operates along identity trajectories into postsecondary science, and demonstrates that simply having access to resources that contribute to students' accumulation of science capital is not sufficient for sustained engagement in science.
