Integration of an ICP-MS Instrument into Advanced Exercises in Undergraduate Science and Engineering

地质学（42）ICP-MS将与我们现有的离子色谱仪一起用于常规课程和学生研究项目中天然样品的化学分析。 在我们的共享分析设施，课程相关的练习和高级研究工作在地质学（5门课程），化学（2门课程），生物学（2门课程）和土木工程（4门课程）的课程的所有四年中实施。 该设施还将用于跨学科的环境研究计划。ICP-MS被用作一种研究工具，为各级学生提供经验：1）入门级学生侧重于从其他地方实施的流域调查项目的选定组成部分改编的练习（例如，Tonn和惠特曼，1996年，科尔比学院）。 学生收集样本，在课外进行分析。 在课堂上，根据概念模型绘制和讨论数据，以确定样本如何获得其组成。 2)中级水平的学生完成更高级的练习，改编自其他地方的各种项目（例如，Ousey，1993年，宾夕法尼亚州立大学; de Wet，1994年，富兰克林和马歇尔学院; Tonn和惠特曼，1996年，科尔比学院; Lee，1998年，奥本大学; Dunnivant等人，1999，哈特威克学院）。 学生收集，准备和分析样本，主要是调查驱动，开放式项目。这些练习允许实施实验设计、实际样品收集和制备技术以及取样和分析策略。 作为最终产品，学生准备大量的书面报告，包括数据演示和解释组件。3)高年级学生使用ICP-MS指导研究项目（论文）改编自他们的研究顾问自己正在进行的奖学金，或在项目主要是学生自己的设计。 这些学生收集，准备和分析样品，并参与规划和实施分析和采样策略和数据解释。 许多论文发表在正式出版物上和/或在科学会议上发表。

Geology (42) The ICP-MS will be used, in conjunction with our existing ion chromatograph, in the chemical analyses of natural samples in both regular courses and student-research projects. In our shared analytical facility, course-related exercises and senior research work are implemented across all four years of the curriculum in the Departments of Geology (5 courses), Chemistry (2 courses), Biology (2 courses), and Civil Engineering (4 courses). The facility will also be utilized in the interdisciplinary Environmental Studies Program. The ICP-MS is being used as a research tool to provide experiences for all levels of students: 1) Introductory level students focus on exercises adapted from selected components of watershed investigation projects implemented elsewhere (e.g., Tonn and Whitman, 1996, Colby College). Students collect samples that are analyzed outside of class. In class, data are plotted and discussed in terms of conceptual models to determine how the samples attained their compositions. 2) Intermediate level students complete more advanced exercises adapted from a variety of projects elsewhere (e.g., Ousey, 1993, Pennsylvania State University; de Wet, 1994, Franklin and Marshall College; Tonn and Whitman, 1996, Colby College; Lee, 1998, Auburn University; Dunnivant et al., 1999, Hartwick College). The students collect, prepare, and analyze samples in largely inquiry-driven, open-ended projects. The exercises allow implementation of experimental design, practical sample collection and preparation techniques, and sampling and analytical strategies. As final products, students prepare substantial written reports that include data presentation and interpretation components. 3) Senior level students use the ICP-MS in directed research projects (theses) adapted from their research advisor's own ongoing scholarship, or in projects largely of the student's own design. These students collect, prepare, and analyze samples, and are involved in planning and implementing analysis and sampling strategies and data interpretation. Many theses result in formal publications and/or presentations at scientific conferences.
