Development of Environmental Geochemistry Modules Across an Earth Science Curriculum

地质学（42）该项目正在本科教学实验室中采用新的分析仪器-一台ICP-AES和一台离子色谱仪。有了这些工具，我们正在调整地球科学课程，把更多的重点放在学习地球化学原理和过程，以下的建议，在Ireton，Manduca和Mogk，“塑造本科地球科学教育的未来”（AGU，1996年）。正在发生五个关键变化。(1)正在重新设计地球化学高级课程，重点放在低温和环境地球化学上。这些课程的实验部分包括技能提高部分和项目部分。(2)该项目的组成部分是教学生开发一个实验设计的研究提案，实施研究，并分析研究结果，重点是技术写作技能。我们的项目的这一部分是适应凯瑟琳卡尔森在设计一个水文地球化学课程在东康涅狄格州州立大学，“现场研究作为学习水文地球化学和科学写作技能的教学工具，”地球科学教育杂志（1999年）第47卷，页的工作。150-157. (3)我们在地质学入门课程中增加了一个基于项目的组件，让学生体验分析仪器的使用，数据收集和分析。该功能采用了Dunnivant等人开发的方法，“一个综合性的流研究设计的本科非专业课程在地球科学，”地球科学教育杂志（1999年）第47卷，页。158-165.学生必须利用当地现有的地下水和地表水资源进行环境调查。(4)我们正在为荣誉课程和独立学习的本科生提供更多的机会，以便在他们的项目中使用先进的分析技术。(5)此外，我们还为本科生提供更多的机会参加高级研讨会。我们已经重新设计了这个研讨会是一个顶点课程。目的是提高学生获取和解释地球化学数据的能力，以支持更广泛的地球科学概念和理论。

Geology (42) This project is incorporating new analytical instrumentation in undergraduate instructional laboratories -- an ICP-AES and an ion chromatograph (IC). With these instruments, we are restructuring the Earth Science curriculum, putting more emphasis on learning geochemical principles and processes, following the recommendations in Ireton, Manduca, and Mogk, "Shaping the Future of Undergraduate Earth Science Education" (AGU, 1996). Five key changes are taking place. (1) Upper-level courses in geochemistry are being redesigned to focus on low-temperature and environmental geochemistry. The laboratory component to these courses includes a skills enhancement component and a project component. (2) The project component is teaching students to develop a research proposal with an experimental design, to implement the research, and to analyze the research findings with an emphasis on technical writing skills. This part of our project is adapting the work of Catherine Carlson in designing a hydro-geochemistry course at Eastern Connecticut State University, "Field Research as a Pedagogical Tool for Learning Hydrogeochemistry and Scientific Writing Skills," Journal of Geoscience Education (1999) Vol. 47, pp. 150-157. (3) We are adding a project-based component to the introductory geology course, giving students experience in the use of analytical instruments, data collection, and analysis. This feature is adapting the approach developed by Dunnivant et al., "A Comprehensive Stream Study Designed for an Undergraduate Non-Majors Course in Earth Science," Journal of Geoscience Education (1999) Vol. 47, pp. 158-165. Students are required to undertake an environmental investigation using locally available groundwater and surface water resources. (4) We are providing enhanced opportunities for undergraduates in the honors program and in independent study to use advanced analytical techniques in their projects. (5) In addition we are providing enhanced opportunities for undergraduates in the senior seminar. We have redesigned this seminar to be a capstone course. The objective is to increase students' ability acquire and interpret geochemical data in support of broader earth science concepts and theories.
