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

改善本科STEM教育：西班牙裔服务机构计划（HSI计划）旨在加强本科STEM教育并建立HSI的能力。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。 这个项目在加州大学，默塞德，将通过提高本科生的兴趣和化学的成功推进HSI计划的目标。 该项目将重新设计实验室课程，以使用学生引导的探究和绿色化学，开发一个建立社区意识的同伴学习环境，并开发短视频，以补充低年级化学课程。这些视频将展示不同的STEM专业人士，他们将把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。由于许多学生都学习化学课程，因此该项目有助于确保不同人群的学生追求STEM职业。该项目旨在提高学生的兴趣，成功以及与教师和同龄人的联系。该项目将重新设计实验室课程，以提高学生对化学内容的理解，化学研究的知识，以及与同龄人和更广泛的校园社区的联系。这些实验室将强调化学研究对环境的影响。伴随重新设计的实验室的视频预计将增加学生对化学职业道路的了解，化学的动机以及学生的学习和坚持。这些视频将以英语和演讲者的母语提供，以促进学生STEM身份的发展，特别是对于不同的学生。将使用学习管理系统中的分析工具来衡量学生使用视频的情况。 最后，同侪领导的团队学习有望提高学生的概念理解，成绩，态度和保留。学生的学习成果将通过学生成绩，前后调查，保留在主要，毕业率，并通过课堂和实验室互动的观察进行评估。还将跟踪学生利用同伴主导机会的持续时间和频率，并与学生态度调查相关联。该项目的视频将免费提供给更广泛的社区，传播这些工具，以提高本科化学学习的目标。 该项目旨在促进对如何支持不同学生在化学方面取得成功的理解，并将学生与STEM职业联系起来。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值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.
