This project is introducing infrared spectroscopy and microscopy as key elements of the freshman laboratory experience, in addition to the current means of investigation. These are powerful but uncomplicated tools applicable to study of many kinds of samples. Infrared is also pedagogically valuable for illustrating molecular dynamism and many aspects of bonding. Microscopy contributes a favorable esthetic element to the student experience of chemistry. This project is addressing student perceptions that chemistry, at least as taught in introductory courses, has little or nothing to do with their lives, by focusing the freshman chemistry laboratory program on working with "real world" materials such as analgesics, household cleaning agents, plastics, textile fibers, vitamins, and the like. This project harnesses the resulting interest by providing opportunities for students, working in groups, to plan and carry out small-scale investigations of such materials in a "directed-inquiry" mode.

本项目将引入红外光谱和显微镜作为新生实验室体验的关键要素，以及目前的调查手段。这些都是强大而简单的工具，适用于多种样本的研究。红外对于说明分子动力学和成键的许多方面也具有教学价值。显微镜为学生的化学体验提供了良好的审美元素。这个项目是为了解决学生们的看法，即化学，至少像在入门课程中教授的那样，与他们的生活几乎没有关系，通过把新生化学实验室计划的重点放在与“现实世界”材料的工作上，如止痛剂、家用清洁剂、塑料、纺织纤维、维生素等。该项目通过为学生提供小组工作的机会，以“定向调查”的方式计划和开展对这类材料的小规模调查，从而利用了由此产生的兴趣。
