Enriching IR Spectroscopy Learning through Inquiry-Based Activities

该项目的目标是开发、实施和评估基于问题（PB）的实验室实验，这些实验与面向过程的指导性探究学习（POGIL）活动相关联，用于学生在分析化学和物理化学中学习傅里叶变换红外（FTIR）光谱学。POGIL活动的重点是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动手探索基本技术和测量的机会，包括衰减全反射（ATR）光谱学，以及研究表面表征等高级主题。通过这笔拨款获得的带有ATR附件的FTIR可用于艾格尼丝斯科特学院的本科研究项目。这个项目的智力价值源于新材料的开发和评估，这些材料整合了课堂上的主动学习活动和基于问题的实验室。独立的模块被设计用于任何高级本科课程，利用主动学习方法来研究FTIR光谱学。所有的活动和实验室实验都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研究FTIR光谱学和/或FTIR光谱学的基本原理的实践者开发高级本科课程的新资源。材料在POGIL网站上传播，该网站是采用这种教学法的课程材料的国家存储库，并通过出版物和讲习班传播。

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.
