Integrating an Inductively Coupled Plasma Mass Spectrometer into the Analytical Geochemistry and Chemistry Curricula

地球系统科学（40）电感耦合等离子体质谱仪已被改造用于本科地质学和化学课程中的探究式学习和个人研究项目。 协作探究式学习方法改编自达特茅斯大学成功的课程项目（环境地质学课程，冯夏红博士，以及Stern，L.一、C. P.张伯伦，J. D. Blum和M. L. Fogel，Isotopic Lessons in a Beer Bottle，J Geoscience艾德，45，157-161，1997）和其他机构（Foos，A. M.，将班级研究项目整合到传统地球化学实验室课程中，J Geoscience艾德，45，322-324，1997）。 在上师地质和化学类，学生设计和执行类，组和个人项目获得直接经验与科学探究的方法。 学生确定一个科学价值的问题，设计和执行抽样和分析策略，收集和解释数据，并提出结果。 环境地球化学班已经完成了一个利用ICP-MS识别当地环境问题的课堂项目，这些问题涉及矿区附近的水和土壤污染。我们还采用了成功的教学模式，将个人研究项目整合到课程中，包括Karen Harpp教授（高露洁大学）的教学模式，以及基于我们自己使用NSF ILI Grant购买的自动X射线粉末衍射仪的经验的教学模式-DUE 9651022。 普通教育学生、职前教师和当地高中学生参加一个以水质问题为重点的区域水项目。 通过这个项目，他们接触到了数据收集和分析的过程，这一经验提高了他们批判性地理解科学原理的能力（例如，史密斯湾L.，在海洋学入门课程中使用关于当地水体的野外和实验室练习来教授基本概念，J Geoscience艾德，43，480 -484，1995）。 重要的课程变化，从这个补助金包括动手与ICP-MS的经验，学生的合作努力，多周的实验，更强调真实数据的分析，以及个人和团体演示的数量增加。 通过使用最先进的分析仪器，实施以探究为基础的教学方法，为我们的学生提供了批判性思维和解决问题的能力，同时为他们在21世纪世纪成功的职业生涯做好准备的机会。

Earth Systems Science (40) The Inductively Coupled Plasma Mass Spectrometer has been adapted for use with inquiry-based learning and individual research projects in the undergraduate Geology and Chemistry curricula. Collaborative inquiry-based learning methods are adapted from successful class projects at Dartmouth University (Environmental Geology class, Dr. Xiahong Feng, and Isotopes as Tracers in the Environmental class described in Stern, L. A., C. P. Chamberlain, J. D. Blum and M. L. Fogel, Isotopic Lessons in a Beer Bottle, J Geoscience Ed, 45, 157-161, 1997), and other institutions (Foos, A. M., Integration of a Class Research Project into a Traditional Geochemistry Lab Course, J Geoscience Ed, 45, 322-324, 1997). In upper division Geology and Chemistry classes, students design and execute class, group, and individual projects gaining direct experience with methods of scientific inquiry. Students identify a question of scientific merit, design and execute a sampling and analysis strategy, collect and interpret data, and present results. The Environmental Geochemistry class has performed a class project by utilizing the ICP-MS in identifying local environmental problems involving water and soil contamination near mine sites. We are also adapting successful pedagogical models that integrate individual research projects into classes, including those of Professor Karen Harpp (Colgate University) and those based on our own experiences with the automated x-ray powder diffractometer purchased by NSF ILI Grant -DUE 9651022. General education students, pre-service teachers, and local high school students participate in a regional water project focusing on water quality issues. Through this project, they have gained exposure to the processes of data collection and analysis, an experience that enhances their ability to critically understand scientific principles (e.g., Smith G. L., Using Field and Laboratory Exercises on Local Water Bodies to Teach Fundamental Concepts in an Introductory Oceanography Course, J Geoscience Ed, 43,480-484, 1995). Important curricular changes resulting from this grant include hands-on experience with the ICP-MS, collaborative student effort, multi-week experiments, more emphasis on analysis of authentic data, and an increased number of individual and group presentations. Implementation of an inquiry-based approach to teaching and learning through use of state-of-the-art analytical instrumentation has provided opportunities for our students in critical thinking and problem-solving skills while preparing them for successful career ventures in the 21st century.
