Course-based Undergraduate Research Experiences (CUREs) have beneficial impacts on students and the capacity to provide authentic research experiences that are accessible and beneficial to all students, especially those from Minoritized Groups. CUREs can be presented in a full semester format (cCURE) and shorter modules incorporated into laboratory courses (mCURE). In this study, protein-centric CUREs were implemented at two minority-serving Community Colleges (CCs) in introductory biology and chemistry courses. Using validated assessment tools, student self-reported gains, and institutional data, we examined student outcomes in three conditions: control, mCURE, and cCURE courses. We also examined whether there was a differential impact on student outcomes by Minoritized Group status. Our findings show that students from Minoritized Groups have improved scientific literacy compared to their White/Asian peers in the cCUREs, whereas students from Minoritized Groups in the control course had lower relative scientific literacy. There was no significant difference in STEM Career Interest between the three conditions. Most significantly, the one-year retention rate of students from the mCURE condition was 24% higher than that seen among control students. Furthermore, retention of students from Minoritized Groups in mCUREs was significantly higher than in control courses, whereas no significant difference was observed in White/Asian students. Taken together, these data suggest that CUREs can be an impactful practice in introductory courses at CCs, especially for students from Minoritized Groups.
基于课程的本科研究经历(CUREs)对学生具有有益影响,并且有能力提供对所有学生,尤其是来自少数群体的学生来说可及且有益的真实研究经历。CUREs可以以完整学期的形式呈现(cCURE),也可以将较短的模块纳入实验课程(mCURE)。在本研究中,以蛋白质为中心的CUREs在两所服务少数群体的社区学院(CCs)的生物学和化学入门课程中实施。我们使用经过验证的评估工具、学生自我报告的收获以及机构数据,在三种情况下考察学生的成果:对照课程、mCURE课程和cCURE课程。我们还考察了少数群体身份对学生成果是否有不同影响。我们的研究结果表明,在cCURE课程中,与白人/亚洲同龄人相比,来自少数群体的学生的科学素养有所提高,而在对照课程中,来自少数群体的学生的相对科学素养较低。三种情况下学生对STEM职业的兴趣没有显著差异。最显著地,mCURE课程组学生的一年留校率比对照组学生高24%。此外,mCURE课程中少数群体学生的留校率显著高于对照课程,而白人/亚洲学生中未观察到显著差异。综上所述,这些数据表明CUREs在社区学院的入门课程中可能是一种有效的做法,尤其是对来自少数群体的学生而言。
