“…While the majority of organic chemistry textbooks typically introduce mechanisms in middle to later chapters, at Campus 1 the curriculum takes a different approach by placing spectroscopy at the forefront by starting the semester with these concepts. , This adaptation reinforces skills in drawing and identifying functional groups while providing experimental evidence to support foundational ideas such as resonance and acid–base chemistry. In the General Chemistry I course at both campuses, the foundation for spectroscopy topics in Organic Chemistry is established through the introduction of basic nomenclature, functional group structure and identification, and introductory IR spectroscopy as part of the curriculum.…”

General chemistry courses serve as foundational curriculum within most STEM undergraduate curricula, and hence, it is essential to assess student knowledge and application of learning outcomes for courses such as Introduction to Chemistry and Organic Chemistry. Within the United States, paper-and-pencil examinations are typical for measuring student understanding of course content. In this project, as an alternative to written examinations, we implemented individual oral examinations. The purpose of this article is to provide guidance on how to implement an oral examination component for student assessment. The example presented took place in two different chemistry courses at two small primarily undergraduate institutions in the Midwest. Here, faculty provide pre-examination information, including preparation for an oral examination in chemistry as well as how to deal with test anxiety in a new testing environment. Students' performances were individually evaluated based on a rubric. Topics of the oral examinations include introductory organic chemistry and infrared (IR) spectroscopy in General Chemistry and intermediate IR spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and mass spectrometry (MS) in Organic Chemistry I.

“…The tutorials were presented in the laboratory component of the first semester in a two-semester organic chemistry sequence. Introducing NMR spectroscopy early in the organic chemistry sequence reinforces general chemistry concepts, nomenclature, and organic structure and provides a building point for the inclusion of spectroscopic concepts throughout the lecture. − …”

Strategies for teaching NMR spectral interpretation in the undergraduate organic chemistry curriculum are often faculty-centered and can lead to student reliance on rote memorization and "guess and check" methods rather than critical-thinking skills for structure determination. This article describes a student-focused methodology for the introduction of NMR spectral interpretation. Guided-inquiry tutorials using NMR prediction tools were developed to enable students to investigate the trends and concepts in 13 C and 1 H NMR spectral interpretation, with an emphasis on making connections between data and foundational chemical knowledge. A systematic approach to solving unknown structure problems is presented, providing a framework for students to organize spectral data and to build molecules from partial structures. The success of this NMR spectroscopy teaching strategy, which can be adapted for either laboratory or lecture environments, was demonstrated both in positive student survey responses as well as in quantitative data showing a significant improvement in exam question scores.
