Developing Scientific Practices with Flexible and Inclusive Course-Based Undergraduate Research Experiences Utilizing Paper Microfluidics

该项目旨在通过开发、实施和评估灵活和包容性的基于课程的本科生研究经验（CUREs）来提高学生在四所不同机构分析化学课程中科学实践的参与度，从而为国家利益服务。治疗已被证明对大学生的坚持、科学认同以及对课程内容和科学技能的学习有积极的影响。肯塔基中心学院、斯基德莫尔学院、新泽西学院和维吉尼亚卫斯理大学的分析化学教师计划开发CUREs和相关的讲师专业发展资源，以支持未来在其他机构的使用。即将开发的cure将采用廉价、安全、灵活的纸质微流体实验室材料，这有望使其他机构的化学课程更容易采用。此外，项目团队计划调查cure如何支持学生在科学实践中的学习和参与。该合作项目旨在支持分析化学教师使用逆向设计开发CURE材料并评估学生的学习情况。该项目的具体目标是：1)为设计灵活的多周cure开发一个理论驱动的过程；2)开发纸质微流控技术和CURE实施的支撑材料；3)评估CURE体验对学生学习的影响。即将开发的分析化学疗法将把传统的比色测定方法转化为一种带有手机检测的纸微流体形式，以测量颜色变化。项目团队计划设计CUREs，以支持学生参与实验设计和执行，数据分析和解释以及科学交流的科学实践。作为逆向设计过程的一部分，将选择学生学习的措施，预计包括通过提高STEM （ELIPSS）中的过程技能来增强学习，以及本科教育（VALUE）中学习的有效评估。预计项目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CUREs中进行的研究的科学成果。美国国家科学基金会改善本科STEM教育（IUSE: EHR）计划支持研究和开发项目，以提高所有学生STEM教育的有效性。通过参与学生学习轨道，该计划支持有前途的实践和工具的创建，探索和实施。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
