基于课程的本科生研究经历（CURE）是增加更多本科生群体研究机会的宝贵工具。我们在高级生物流体力学课程中实施了 CURE，该课程主要使用翻转课堂方法进行教学。由于班级规模较大，学生们分析了我们实验室之一公开提供的数据。然后，学生团队根据数据分析提出假设，并设计一组体外和体内实验来检验这些假设。然后，全班评价最高的假设和实验在我们的实验室进行了测试。课程结束时，通过自我报告评估学生的收获，并与参与传统新生本科暑期研究经历的学生的自我报告进行比较。虽然 CURE 项目的学生在基于研究的技能的自我评估方面取得了一定的进步，但他们自我报告的进步在统计上显着低于参与传统研究经历的学生报告的进步。我们相信，可以通过在较低级别的班级中实施来改进 CURE，使学生能够观察实验室实验，并在整个假设发展和实验设计过程中提供额外的反馈。总体而言，CURE 是一种扩展研究经验的创新方式，特别是对于在本科教育期间经常不参与假设驱动研究的工程专业学生而言。
Course-based undergraduate research experiences (CURE) are a valuable tool to increase research exposure for larger undergraduate cohorts. We implemented a CURE within a senior-level biofluid mechanics course that was primarily taught using a flipped classroom approach. Due to the large class size, the students analyzed data that was publicly available and produced by one of our laboratories. Student teams then developed hypotheses based on the data analysis and designed a set of in vitro and in vivo experiments to test those hypotheses. The hypotheses and experiments that were most highly rated by the class were then tested in our laboratory. At the end of the class, student gains were assessed by self-report and compared to those self-reported by students engaging in a traditional freshman undergraduate summer research experience. While the students in the CURE reported moderate gains in self-assessment of research-based skills, their self-reported gains were statistically significantly lower than those reported by students who participated in the traditional research experience. We believe that the CURE could be improved through implementation in a lower level class, enabling students to observe laboratory experiments, and providing additional feedback throughout the hypothesis development and experimental design process. Overall, the CURE is an innovative way to expand research experiences, in particular for engineering students who often do not participate in hypothesis-driven research during their undergraduate education.
