Chemistry (12)This project is focusing on the concept of molecular structure within the chemistry laboratory curriculum. The overall goal of the project is to strengthen student understanding of molecular structure through use of nuclear magnetic resonance (NMR) as an essential method for obtaining structural information. With the revised curriculum, students are developing expertise using NMR through a systematic introduction to NMR theory and concepts. Furthermore, the vertical integration in lab courses is allowing students to build on previous experiences with NMR to develop increasingly richer understanding of molecular structure. This new laboratory curriculum is being assessed using the "Perspectives of Chemists" framework, a set of tools designed by previously supported NSF initiatives. This framework divides chemistry into overarching ideas that permeate the curriculum and allows for assessing the progression of student understanding around these "perspectives". Applying these classroom curriculum models to the laboratory setting represents a new extension of the framework. By explicitly demonstrating the use of NMR in practical applications and by allowing hands on access to the instrument, students are gaining insight into chemical problem solving and confidence in their abilities to gather, analyze, and interpret structural features of molecules.

化学（12）这个项目的重点是化学实验室课程中的分子结构的概念。该项目的总体目标是通过使用核磁共振（NMR）作为获取结构信息的基本方法，加强学生对分子结构的理解。 随着修订后的课程，学生通过系统地介绍NMR理论和概念，利用NMR开发专业知识。 此外，实验室课程的垂直整合允许学生建立在以前的NMR经验的基础上，以发展对分子结构越来越丰富的理解。这一新的实验室课程正在使用“化学家的观点”框架进行评估，这是一套由以前支持的NSF倡议设计的工具。 该框架将化学划分为贯穿课程的总体思想，并允许评估学生围绕这些“观点”的理解进展。 将这些课堂课程模型应用到实验室环境中是该框架的一个新的扩展。通过明确展示NMR在实际应用中的使用，并允许动手使用仪器，学生们可以深入了解化学问题的解决方法，并对他们收集，分析和解释分子结构特征的能力充满信心。
