Guided Inquiry Experiments with Fourier Transform NMR Spectroscopy

化学12正在为普通和有机化学入门课程开发指导性探究实验，这些课程使用核磁共振光谱分析作为一种综合的动手方法，为从实验中得出结论提供必要的证据。该项目正在将一台瓦里安EM-360磁体改装成一台Anasazi 60 MHz EFT核磁共振(FT核磁共振)光谱仪。学生能够有效地运行样本并分析他们的数据。对于以前没有亲身接触过核磁共振仪器的学生来说，这是一个重大的进步。这也适用于参加高级化学课程的高中生。学生能够获得光谱，并根据他们自己的核磁共振数据得出关于他们实验的结论。通过开发结合核磁共振分析的指导性探究实验来改善实验室中的概念学习是这项提议的主要目标。该项目正在评估该项目直接导致的概念学习、批判性推理技能、学生兴趣和动机方面的变化。指导性探究实验为教育工作者提供了大学教授、高中教师和学生之间合作关系的选择。老师们正在将他们从这个项目中获得的技能和知识传授给他们的预科学生。

Chemistry 12Guided inquiry experiments are being developed for introductory general and organic chemistry courses that use NMR spectroscopic analysis as an integrated hands-on method that provides evidence essential for reaching conclusions from the experiments. The project is converting a Varian EM-360 magnet into an Anasazi 60 MHz Eft NMR (FT NMR) spectrometer. Students are able to effectively run samples and analyze their data. This represents a significant improvement for students who have not previously had the benefit of hands-on access to NMR instrumentation. This applies to participating high school students taking advanced chemistry as well. Students are able to obtain spectra and reach conclusions about their experiments based upon their own NMR data. Improving conceptual learning in the laboratory through development of guided inquiry experiments integrating NMR analysis is a major goal of this proposal. The project is evaluating changes in conceptual learning, critical reasoning skills, student interest and motivation resulting directly from the project. Guided inquiry experiments are providing educators with options for collaborative relationships among college professors, high school teachers and students. The teachers are passing on their acquired skills and knowledge from this project to their pre-collegiate students.
