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.

地质学 (42) 该项目正在本科生教学实验室中采用新的分析仪器——ICP-AES 和离子色谱仪 (IC)。借助这些工具，我们正在重组地球科学课程，按照 Ireton、Manduca 和 Mogk“塑造本科生地球科学教育的未来”（AGU，1996）中的建议，更加重视学习地球化学原理和过程。正在发生五个关键变化。 （1）重新设计地球化学高级课程，以低温和环境地球化学为重点。这些课程的实验室部分包括技能增强部分和项目部分。 (2) 项目组成部分是教学生通过实验设计制定研究计划，实施研究，并分析研究结果，重点是技术写作技能。我们项目的这一部分正在改编凯瑟琳·卡尔森在东康涅狄格州立大学设计水文地球化学课程的工作，“现场研究作为学习水文地球化学和科学写作技巧的教学工具”，地球科学教育杂志（1999）卷。 47，第 150-157 页。 (3) 我们在地质学入门课程中添加了基于项目的部分，让学生体验分析仪器的使用、数据收集和分析。此功能采用了 Dunnivant 等人开发的方法，“为地球科学本科非专业课程设计的综合流研究”，地球科学教育杂志 (1999) 第 1 卷。 47，第 158-165 页。学生必须使用当地可用的地下水和地表水资源进行环境调查。 (4) 我们为荣誉课程和独立学习的本科生提供更多机会，让他们在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参加高级研讨会的机会。我们已将本次研讨会重新设计为顶点课程。目标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。
