Geology (42) We have implemented a hierarchical set of research exercises (e.g., Johnson & Stahl, 1997, Central Michigan University; Videtich, 1997, Grand Valley State University; Niemitz, 1996, Dickinson College) that utilize the ICP-AES across sophomore to senior level courses in the environmental science concentration within the geology and biology majors at MSU. 1) Initial exercises in the sequence stress practical sample collection, preparation, and analysis techniques for air, water, and soil samples in sophomore level environmental analytical chemistry and soil science courses. These courses serve as the analytical foundation for future exercises that utilize the ICP and other existing analytical equipment (e.g. XRD, SEM, ion chromatography). 2) Junior-level students complete progressively more complex course-based guided research using the ICP for applications specific to upper-level courses in applied environmental microbiology, geohydrology, and environmental geochemistry. The exercises build on experimental design, implementation, and analysis skills and allow students the opportunity to utilize variable analytical strategies. With each exercise students prepare a written, visual, and/or oral presentation of the results that includes data presentation and interpretation components. Junior level students use the ICP for inquiry-based research projects involving the analysis of rocks and minerals in the petrology and mineralogy courses for geology majors. 3) As a capstone to the environmental science curriculum, senior-level students use the ICP-AES facility to design and implement an independent, semester-long research project in a senior seminar course in environmental science. Research projects are either associated with on-going faculty research or completely of the students' own design. Students are involved in all phases of the research from planning and implementation, to sample collection and analysis, to final data interpretation and presentation. The project culminates in a substantial written report and an oral presentation at a semester-end class symposium. The ICP is also being used to complete more substantial, independent, senior projects (theses) in environmental science, geology, chemistry, and biology with the guidance of faculty mentors. Many of these projects are presented at scientific conferences and result in formal publications. The ICP-AES has prepared students for employment in the environmental industry and for developing independent research skills for those attending graduate school.

地质学（42）我们已经实施了一套分层的研究练习（例如，约翰逊斯塔尔，1997年，中密歇根大学; Videtich，1997年，大峡谷州立大学; Niemitz，1996年，迪金森学院），在密歇根州立大学地质学和生物学专业的环境科学集中的大二到高年级课程中利用ICP-AES。 1)在大二环境分析化学和土壤科学课程中，在序列中强调实际样品收集，制备和空气，水和土壤样品的分析技术的初步练习。这些课程为将来使用ICP和其他现有分析设备（如XRD、SEM、离子色谱）的练习奠定了分析基础。 2)初级学生完成逐步更复杂的课程为基础的指导研究使用ICP特定于应用环境微生物学，地质水文学和环境地球化学的高级课程的应用。这些练习建立在实验设计，实施和分析技能的基础上，让学生有机会利用变量分析策略。 每个练习学生都要准备一份书面的、视觉的和/或口头的结果报告，其中包括数据报告和解释部分。 初级学生使用ICP进行基于探究的研究项目，涉及地质学专业岩石学和矿物学课程中的岩石和矿物分析。 3)作为环境科学课程的顶点，高年级学生使用ICP-AES设施在环境科学高级研讨会课程中设计和实施一个独立的，为期一学期的研究项目。 研究项目要么与正在进行的教师研究有关，要么完全是学生自己的设计。 学生参与研究的所有阶段，从规划和实施，到样本收集和分析，再到最终的数据解释和展示。该专题以一份实质性的书面报告和在学期末的课堂研讨会上的口头报告而告终。 ICP也被用来完成更多的实质性的，独立的，高级项目（论文）在环境科学，地质学，化学和生物学与教师导师的指导。 其中许多项目都在科学会议上提出，并发表正式出版物。ICP-AES为学生在环境行业就业做好了准备，并为那些就读研究生院的学生培养了独立的研究技能。
