The goal of this project is to develop, implement and evaluate problem-based (PB) laboratory experiments linked to process-oriented guided-inquiry learning (POGIL) activities for student learning of Fourier-transform infrared (FTIR) spectroscopy in analytical and physical chemistry. The POGIL activities focus on student understanding of key IR spectroscopic concepts. The PB laboratory experiments provide students with hands-on opportunities to explore fundamental techniques and measurements, including attenuated total reflectance (ATR) spectroscopy, as well as investigate advanced topics such as the characterization of surfaces. The FTIR with ATR accessory acquired through this grant is available for Agnes Scott College's undergraduate research program. The intellectual merit of this project stems from the development and evaluation of new materials that integrate active-learning in-class activities and problem-based laboratories. Self-contained modules are designed to be used in any upper-level undergraduate course utilizing active learning methods to study FTIR spectroscopy. All activities and laboratory experiments are peer reviewed and classroom tested, which adds to the strength of the evaluation plan. The broader impact includes the development of novel resources for upper-level undergraduate courses for any practitioner wishing to use active learning methods to study FTIR spectroscopy and/or fundamental principles illustrated by FTIR spectroscopy. Materials are disseminated on the POGIL website, a national repository for curricular materials employing this pedagogy, and through publications and workshops.

该项目的目标是开发、实施和评估与面向过程的引导探究学习 (POGIL) 活动相关的基于问题 (PB) 的实验室实验，以便学生学习分析和物理化学中的傅里叶变换红外 (FTIR) 光谱。 POGIL 活动侧重于学生对关键红外光谱概念的理解。 PB 实验室实验为学生提供了探索基本技术和测量的实践机会，包括衰减全反射 (ATR) 光谱，以及研究表面表征等高级主题。通过本次资助获得的带有 ATR 附件的 FTIR 可用于艾格尼丝·斯科特学院的本科研究项目。 该项目的智力价值源于新材料的开发和评估，这些新材料整合了主动学习的课堂活动和基于问题的实验室。独立模块旨在用于任何利用主动学习方法来研究 FTIR 光谱的高年级本科课程。所有活动和实验室实验均经过同行评审和课堂测试，这增加了评估计划的强度。 更广泛的影响包括为任何希望使用主动学习方法来研究 FTIR 光谱和/或 FTIR 光谱说明的基本原理的从业者开发高级本科课程的新颖资源。材料在 POGIL 网站（一个采用这种教学法的国家课程材料存储库）上以及通过出版物和研讨会传播。
