Authentic research experiences in research laboratories run by professors do a far better job of developing students' research skills and improving student retention in science than traditional laboratory experiences associated with a course. This is particularly true with groups who traditionally have not entered science fields. Authentic research experiences provide motivation to learn the research skills and demonstrate rewards in solving research problems. CUREs (Course-based Undergraduate Research Experiences) have been created to provide all science students with a real research experience. However, little is known about the impacts of CUREs on student research skills and retention in science. The University of Northern Colorado has developed an introductory biology CURE based on Tigriopus californicus, a small marine organism, and initial results indicate the CURE increases students' content knowledge and improves their motivation towards learning biology, both of which have been shown to increase retention. This project will expand the CURE to three different institutions: a Liberal Arts University; a large, Hispanic-Serving Research University; and a small, Women's Minority-Serving College. Using these diverse student populations, this project will determine if the CURE improves students' content knowledge, research skills, motivation towards learning biology, and retention in biology. Most research conducted on CURE student outcomes relies heavily on student self-reported learning gains, has been completed with self-selected student populations, and has not been conducted with student populations who are underrepresented in the STEM disciplines. The proposed project will enhance and expand current knowledge by adding to the existing CURE research including: (1) testing aspects of a recently developed CURE impacts model; (2) the exploration of CURE impacts on students' experimental design skills, motivation, science identity, and persistence in science; and (3) the examination of the impacts of CUREs on diverse student groups, including minorities and first-generation students. This project will also greatly expand our understanding of Tigriopus californicus, about which very little is currently known despite its important place at the base of the marine food chain. Finally, this project will potentially broaden participation of underrepresented groups in the biological sciences.

由教授开展的研究实验室的真实研究经验在发展学生的研究技能和提高科学的学生保留方面做得比与课程相关的传统实验室经验更好。对于传统上没有进入科学领域的团体，尤其如此。真实的研究经验提供了学习研究技能并证明解决研究问题的奖励的动力。已经创建了治疗方法（基于课程的本科研究经验），以为所有科学专业的学生提供真正的研究经验。但是，关于治疗对学生研究技能和科学保留的影响知之甚少。北科罗拉多大学基于加利福尼亚州的tigriopus，开发了一种介绍性的生物学治疗，这是一种小型海洋生物体，最初的结果表明，治愈方法增加了学生的内容知识并提高了他们对学习生物学的动力，这两种都已证明可以增加保留率。该项目将把治疗方法扩展到三个不同的机构：一所文科大学；一所大型西班牙裔研究大学；还有一所小型女性服务学院。使用这些多样化的学生人群，该项目将确定CURE是否可以提高学生的内容知识，研究技能，学习生物学的动机以及在生物学中的保留。关于治愈学生成果的大多数研究都在很大程度上依赖于学生自我报告的学习成就，已经完成了自我选择的学生群体，并且尚未与STEM学科中代表性不足的学生群体进行。拟议的项目将通过增加现有的CURE研究来增强和扩展当前知识，包括：（1）测试最近开发的CURE IMPACTS模型的测试方面； （2）探索治疗对学生实验设计技能，动机，科学认同和科学持久性的影响； （3）检查治疗方法对包括少数民族和第一代学生在内的不同学生群体的影响。该项目还将大大扩展我们对Tigriopus Californicus的理解，尽管该项目在海洋食物链的基础上很重要，但目前几乎没有知名。最后，该项目可能会扩大代表性不足的群体在生物科学中的参与。
