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的实验室组成部分的重大变化（化学专业的定量和工具分析的一个学期课程，以及非化学专业的分析化学介绍课程）。 这些变化是化学部门更大的课程改革的一部分。 这些更改包括（a）为大部分工作引入基于角色的合作学习方法以及（b）基于问题的工业相关性工作的发展和实施。这些修订的目的是纠正NSF和其他人最近强调的BS化学家教育中的各种缩写。 新的实验室含量更加重视光谱和色谱法。介绍了以下新技术：微波辅助消化和提取，离子色谱，固相微萃取，自动库尔仪karl-fisher滴定器和FT-IR显微镜。 用电子捕获检测和商业集成流动注射单元的毛细血管色谱仪的获取分别在气相色谱和流动注射分析区域提供了升级。尤其是仪器的某些一般原理，尤其是分子吸收光谱法的教学方法是基于一种综合方法，该方法始于建模和发展，尽管模块化仪器的构造构建了商业仪器的评估。包括有关数据处理和处理的实验。一个工业咨询委员会为设计许多实验工作提供了帮助，包括基于问题的实验。已经建立了一个网站作为新教学材料的一部分，并将通过教育会议和期刊传播。
