This project involves major changes in the laboratory component of three undergraduate analytical chemistry courses (the one-semester courses in quantitative and instrumental analysis for chemistry majors, and the one-semester course in analytical chemise for non-chemistry majors). These changes are part of larger curricular reform in the Chemistry Department. The changes include (a) the introduction of a role-based cooperative learning approach to much of the work and (b) the development and implementation of problem-based work of industrial relevance. The goal of these revisions is to redress the various short-comings in the education of BS chemists recently highlighted by the NSF and others. The new laboratory content gives more emphasis to spectroscopy and chromatography. The following new techniques are introduced: microwave assisted digestions and extractions, ion chromatography, solid phase microextraction, automatic coulometric Karl-Fisher titrimetry, and FT-IR microscopy. The acquisition of a capillary chromatograph with electron capture detection and a commercial integrated flow injection unit provides upgrades in the areas of gas chromatography and flow injection analysis, respectively. The approach to the teaching of some general principles of instruments, and of molecular absorption spectrometry in particular, is based on an integrated approach which starts with modeling and progresses though the construction of modular instruments to the evaluation of commercial instruments. Experiments on data handling and processing are included. An Industrial Advisory Board provides help in devising much of the experimental work, including the problem-based experiments. A web site has been established as part of the new teaching materials and information will be disseminated through educational conferences and journals.

该项目涉及三个本科分析化学课程（化学专业的定量和仪器分析一学期课程，非化学专业的分析化学一学期课程）的实验室组成的重大变化。 这些变化是化学系更大的课程改革的一部分。 这些变化包括：（a）对大部分工作采用基于角色的合作学习方法;（B）制定和执行与工业相关的基于问题的工作。这些修订的目标是纠正NSF和其他机构最近强调的BS化学家教育中的各种缺陷。 新的实验内容更加强调光谱学和色谱学。介绍了微波消解和萃取、离子色谱、固相微萃取、自动库仑卡尔费休滴定法和傅立叶变换红外显微镜等新技术。 采购一台带电子捕获检测器的毛细管色谱仪和一台商用集成流动注射装置，分别为气相色谱和流动注射分析领域提供了升级。仪器的一些一般原理的教学方法，特别是分子吸收光谱法，是基于一个综合的方法，从建模开始，通过模块化仪器的建设，商业仪器的评估进展。包括数据处理和加工实验。工业咨询委员会在设计大部分实验工作方面提供帮助，包括基于问题的实验。作为新教材的一部分，已经建立了一个网站，并将通过教育会议和期刊传播信息。
