One Early Course-Based Undergraduate Research Experience Produces Sustainable Knowledge Gains but only Transient Perception Gains

摘要

Universities have been called upon to integrate research experiences into early, introductory courses to better prepare our STEM workforce. This call is primarily based on short-term studies that link research experiences with knowledge and perception gains. However, the influence of pre-existing student characteristics has not been fully disentangled from the research experience, and the long-term stability of these gains is uncertain. To address these issues, we integrated a course-based undergraduate research experience (CURE) into randomly assigned sections of a required freshman-level biology laboratory course. We previously reported that this CURE resulted in immediate targeted knowledge and perception gains. Here, we evaluate the stability of these gains as students progressed through a biology degree program. At sophomore year, the impact of the CURE on student perception was still apparent. When compared to controls, students who participated in the CURE perceived a greater understanding of what researchers do and an increased interest in pursuing a research career. However, by senior year, these positive perceptions had fallen to levels shared by control groups. Targeted knowledge gains persisted throughout this study. Our results support CURE logic models predicting that multiple CUREs will be required to sustain perception gains.
