In this study, we compare students' explanations of natural selection for humans versus a nonhuman animal (cheetah) at different times during biology instruction. We found \"taxon\" to be a significant predictor of the content of students' explanations. Responses to \"cheetah\" prompts contained a larger number and diversity of key concepts (e.g., variation, heritability, differential reproduction) and fewer naïve ideas (e.g., need, adapt) when compared with responses to an isomorphic prompt containing \"human\" as the organism. Overall, instruction increased the prevalence of key concepts, reduced naïve ideas, and caused a modest reduction in differences due to taxon.

We compare these perspectives to previous studies in the literature in an effort to identify commonalities across all sources and offer potential insights for advancing CURE TA PD efforts across a diversity of institutional environments. We propose that the most effective CURE TA PD programs will promote the use of CURE-specific instructional strategies as benchmarks for guiding change in teaching practices and should focus on three major elements: 1) enhancement of research and teaching acumen, 2) development of effective and inclusive mentoring practices, and 3) identification and understanding of the factors that make CUREs a unique learning experience.</p>","PeriodicalId":56321,"journal":{"name":"Cbe-Life Sciences Education","volume":"22 4","pages":"es4"},"PeriodicalIF":3.7,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10756030/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41221459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Covid-19 pandemic challenged the program, as colleges shuttered laboratories and other facilities. Some mentors worried that lab-based research experiences would not be possible under such conditions. The first full-year pandemic cohort, however, demonstrated the resilience of the program and its participants. To assess the ongoing impact of CRSP and how it adapted using new modalities, we interviewed college-based directors, surveyed students and mentors, and held focus groups with mentors. Directors described how their colleges adapted to preserve all prepandemic components of the program. Mentors detailed their strategies for engaging students in authentic research experiences in virtual and other formats.
