This project seeks to serve the national interest by developing, implementing, and assessing flexible and inclusive Course-Based Undergraduate Research Experiences (CUREs) to enhance students’ engagement with scientific practices in analytical chemistry courses at four diverse institutions. CUREs have been shown to positively impact college students’ persistence, scientific identity, and learning of both course content and science skills. Analytical chemistry faculty members from Centre College of Kentucky, Skidmore College, The College of New Jersey, and Virginia Wesleyan University plan to develop the CUREs and associated instructor professional development resources to support their use at other institutions in the future. The CUREs to be developed will employ paper microfluidic laboratory materials that are inexpensive, safe, and flexible, which is expected to make them easier for chemistry courses at other institutions to adopt. Additionally, the project team plans to investigate how the CUREs support student learning and engagement in scientific practices.The collaborative project intends to support analytical chemistry faculty members in the use of backward design to develop the CURE materials and assess student learning. The specific aims of the project are to: 1) develop a theory-driven process for the design of flexible multi-week CUREs; 2) develop paper microfluidic technology and support materials for CURE implementation; and 3) assess the impact of the CURE experiences on student learning. The analytical chemistry CUREs to be developed will translate traditional colorimetric assays into a paper microfluidic format with cell phone detection to measure color changes. The project team plans to design the CUREs to support students in engaging in the scientific practices of experimental design and execution, data analysis and interpretation, and scientific communication. Measures of student learning will be selected as part of the backward design process and are expected to include Enhancing Learning by Improving Process Skills in STEM (ELIPSS) and Valid Assessment of Learning in Undergraduate Education (VALUE) rubrics. The project deliverables are expected to include not only course materials and results of assessments of student learning, but also scientific results from the research conducted within the CUREs. The NSF Improving Undergraduate STEM Education (IUSE: EHR) program supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目旨在通过开发，实施和评估基于课程的本科研究经验（治疗）来增强学生参与四个潜水员机构的分析化学课程中的科学实践，以促进国家利益。疗法已被证明会对大学生的持久性，科学身份以及学习课程内容和科学技能的学习产生积极影响。肯塔基州中心学院，斯基德莫尔学院，新泽西学院和弗吉尼亚卫斯理大学的分析化学教师计划开发治疗疗法和相关的教师专业发展资源，以支持他们将来在其他机构中使用。要开发的治疗方法将采用纸质微流体实验室材料，这些实验室材料廉价，安全且灵活，这有望使其更容易在其他机构采用的化学课程中。此外，项目团队计划调查如何治愈科学实践的学生学习和参与。协作项目旨在支持分析化学教师使用向后设计来开发治疗材料并评估学生学习。该项目的具体目的是：1）开发以理论驱动的过程来设计灵活的多周治疗方法； 2）开发纸张微流体技术和支持材料以治愈实施； 3）评估治疗经验对学生学习的影响。要开发的分析化学治疗方法将通过手机检测来将传统的比色法评估转化为纸张微流体格式，以测量颜色变化。项目团队计划设计治疗方法，以支持学生从事实验设计和执行，数据分析和解释以及科学沟通的科学实践。学生学习的度量将被选为向后设计过程的一部分，并有望包括通过提高STEM（ELIPS）的过程技能的增强学习以及对本科教育（价值）专栏中学习的有效评估。预计该项目的可交付成果不仅包括课程材料和学生学习评估的结果，还包括在治疗中进行的研究的科学结果。 NSF改善了本科STEM教育（IUSE：EHR）计划支持研发项目，以提高所有学生STEM教育的有效性。通过参与的学生学习轨道，该计划支持了承诺实践和工具的创建，探索和实施。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估的评估来支持的。
