Building Capacity: Improving the Undergraduate Chemistry Experience by Green Chemistry, Active-learning, and Peer-led Experiences

改善本科生STEM教育：西班牙裔服务机构计划(HSI计划)旨在加强本科生STEM教育，并在HSIS建设能力。HSI计划支持的项目也将产生关于如何实现这些目标的新知识。加州大学默塞德分校的这个项目将通过提高本科生对化学的兴趣和成功来推进HSI计划的目标。该项目将重新设计实验室课程，使用学生引导的探究和绿色化学，发展建立社区意识的同行学习环境，并开发短视频来补充低级化学课程。这些视频将以不同的STEM专业人员为特色，他们将把在课程中学到的化学概念与他们在当前STEM职业生涯中如何使用这些概念联系起来。由于许多学生都在学习化学课程，该项目有助于确保不同群体的学生从事STEM职业。该项目旨在提高学生的兴趣、成就感以及与教职员工和同行的联系。该项目将重新设计实验室课程，以加强学生对化学内容的理解，化学研究的知识，以及与同行和更广泛的校园社区的联系。这些实验室将强调化学研究的环境影响。重新设计的实验室附带的视频预计将增加学生对化学职业道路的了解，对化学的动力，以及学生的学习和坚持不懈。这些视频将以英语和说话者的母语提供，以促进学生STEM身份的发展，特别是针对不同类别的学生。学习管理系统中提供的分析工具将用于衡量学生对视频的使用情况。最后，同伴主导的团队学习有望提高学生的概念理解、成绩、态度和保持能力。学生的学习结果将通过学生成绩、任职前调查、专业留存、毕业率以及对课堂和实验室互动的观察来评估。学生使用同伴主导机会的持续时间和频率也将被跟踪，并与学生态度调查相关联。项目视频将向更广泛的社区免费提供，目的是传播这些工具来加强本科生的化学学习。该项目旨在促进对如何支持不同学生在化学上取得成功并将学生与STEM职业联系起来的理解。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The Improving Undergraduate STEM Education: Hispanic-Serving Institutions Program (HSI Program) aims to enhance undergraduate STEM education and build capacity at HSIs. Projects supported by the HSI program will also generate new knowledge about how to achieve these aims. This project at the University of California, Merced, will advance the aims of the HSI Program by increasing undergraduate student interest and success in chemistry. The project will redesign laboratory courses to use student-guided inquiry and green chemistry, develop a peer-learning environment that builds a sense of community, and develop short videos to complement lower-division chemistry courses. These videos will feature diverse STEM professionals who will connect chemistry concepts learned in the course to how they use these concepts in their current STEM career. Because many students take chemistry courses, this project can contribute to ensuring that a diverse population of students pursue STEM careers.The project aims to increase student interest, success, and connection to faculty and peers. The project will redesign laboratory courses to enhance student understanding of chemistry content, knowledge of chemistry research, and connection to peers and the broader campus community. The labs will emphasize the environmental implications of chemistry research. Videos that accompany the redesigned labs are expected to increase student knowledge of career paths in chemistry, motivation for chemistry, and student learning and persistence. The videos will be available in English and in the speaker's native language, to foster the development of student STEM identity, in particular for diverse students. Analytics tools available in the learning management system will be used to measure the use of the videos by students. Finally, peer-led team-learning is expected to improve students' conceptual understanding, grades, attitudes, and retention. Student learning outcomes will be assessed by student grades, pre-post surveys, retention in the major, graduation rates, and by observation of classroom and lab interactions. The duration and frequency of student use of the peer-led opportunities will also be tracked and correlated with surveys of student attitudes. The project videos will be freely available to the broader community, with the goal of disseminating these tools to enhance learning of undergraduate chemistry. This project seeks to advance understanding of how to support diverse students' success in chemistry and to connect students with STEM careers.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.
