项目摘要

Geology (42) This project has two objectives. One is to provide University of Northern Iowa students with an opportunity to learn the fundamental concepts that explain observed patterns of surface and subsurface water resources pollution. The other is to provide them with opportunities to improve their analytical skills by using modern laboratory equipment. The project is centered on the use of a new ion chromatography system. The installation of this system has enhanced the analytical capability of the undergraduate hydrogeology laboratory in the Department of Earth Science. This new ion chromatograph is being used to monitor water flow and quality using a newly built on-campus monitoring well site. A related dimension of our project is an on-going process of laboratory curriculum improvement. In this project we are implementing the recommendations of Texley and Wild, "NSTA Pathways to the Science Standards: Guidelines for Moving the Vision into Practice," National Science Teachers Association, 1997, and following the recommendations of Clough and Clark, "Cookbooks and Constructivism: A Better Approach to Laboratory Activities," The Science Teacher, Vol. 61, No. 2 (1994) pp. 34-37. New exercises are being added to the lab component of various courses, such as Hydrogeology, Environmental Hydrology, and Physical Geology. These exercises are providing the students with increased opportunities to develop critical thinking skills and a scientific attitude. Many of these exercises are field-based hands-on experiences designed to facilitate student understanding of the fundamentals of water-rock interactions in subsurface geologic systems. In the impacted courses, students are collecting ground water and stream water samples from polluted and unpolluted areas, from areas of varying land use practices, and from landfill sites. Students are then analyzing these samples using ion chromatography for their common inorganic ion content. Students are also studying groundwater flow by using ion tracers (bromide, chloride, and others) in both simulated lab systems and in the field plots. These exercises are teaching them the concepts of prevalent chemical characters and leachate migration, improving their understanding of how land use practices cause subsurface water pollution, and many of the derivative environmental consequences of subsurface water pollution. This project is making it easier for the students to find a link between their classroom and laboratory learning and the real field situation. This expansion of available laboratory exercises in water-related classes is giving our students more opportunities to prepare for employment in environmental services companies as well as for further study at the graduate level.
地质学(42)本项目有两个目标。一个是为北方爱荷华州大学的学生提供一个学习解释观测到的地表和地下水资源污染模式的基本概念的机会。另一个是为他们提供机会,通过使用现代化的实验室设备来提高他们的分析技能。该项目的重点是使用一种新的离子色谱系统。该系统的安装提高了地球科学系本科水文地质实验室的分析能力。这种新的离子色谱仪正在使用一个新建成的校园监测井场来监测水的流量和质量。我们项目的一个相关方面是实验室课程改进的持续过程。在这个项目中,我们正在实施Texley和Wild的建议,“NSTA科学标准之路:将愿景付诸实践的指导方针”,国家科学教师协会,1997年,并遵循Clough和Clark的建议,“Cookbooks和建构主义:实验室活动的更好方法”,科学教师,第61卷,第2号(1994)页。34-37.新的练习被添加到各种课程的实验室部分,如水文地质学,环境水文学和物理地质学。这些练习为学生提供了更多的机会来培养批判性思维技能和科学态度。这些练习中有许多是基于实地的实践经验,旨在促进学生对地下地质系统中水-岩相互作用的基本原理的理解。在受影响的课程中,学生们正在从污染和未污染地区、不同土地使用方式的地区以及垃圾填埋场收集地下水和溪流水样本。然后学生使用离子色谱法分析这些样品中常见的无机离子含量。学生们还通过使用离子示踪剂(溴化物、氯化物等)在模拟实验室系统和野外地块中研究地下水流动。这些练习教他们普遍的化学特性和渗滤液迁移的概念,提高他们的土地使用的做法如何造成地下水污染,地下水污染的衍生环境后果的理解。这个项目使学生更容易找到他们的课堂和实验室学习与真实的现场情况之间的联系。在与水有关的课程中扩大可用的实验室练习,使我们的学生有更多的机会为环境服务公司的就业做准备,并为研究生阶段的进一步学习做准备。
