Enhancement Interdisciplinary Environmental Science Curriculum Using a Gas Chromatograph/Mass Spectrometer and Ion Chromatograph in Undergraduate Laboratories

跨学科(99)为了应对马萨诸塞州东南部的快速经济发展，布里奇沃特州立大学大力加强其科学项目，因为对训练有素的环境专业人员的需求日益增加。正在实施化学环境集中，以加入生物学、地球科学和地理学以及管理科学的集中，以培养能够处理当前和未来环境问题的教师、技术人员和研究生研究人员。这为学生提供了广泛的实践经验，使用最先进的仪器进行环境分析。为了为这一计划提供必要的仪器，化学和生物系正在建立一个实验室，配备一台HP 6890气相色谱仪/HP 5973质量选择检测器串联装置和Lachat离子色谱装置，这两台仪器都是用于环境分析的强大仪器。在不同的学科中，正在开发一套适应主动学习教学法的实验室实验，以使用新工具为学生提供协作的动手体验。该项目的受益者包括所有科学学科的学生，加强了生物、化学、地球科学和地理等环境专业与环境管理之间的联系。该项目通过促进采用和实施增强的实验室课程，结合主动学习教学法，从而为当前的本科生研究计划注入活力，从而有利于教师的发展。此外，该项目还通过提高化学和生物职前教师以及通过布里奇沃特州立大学分水岭实验室专业发展计划支持的在职教师的实验室技能和对当前技术的了解，促进了教师准备工作。一名环境项目专家正在进行评估，以评估动手实验室在提高学生学习和对该学科的兴趣方面的有效性。在研讨会和讲习班以及相关期刊上报告了新实验室实验的开发结果。它们还被张贴在所涉及的各个学科的网站上。

Interdisciplinary (99) In response to the rapid economic development in Southeastern Massachusetts, Bridgewater State College has made strong efforts to strengthen its science programs due to the increasing need for trained environmental professionals. An Environmental concentration in Chemistry is being implemented to join concentrations in Biology, Earth Science and Geography, and Management Science in order to prepare teachers, technicians, and graduate researchers capable of dealing with the current and future environmental issues. This provides students with extensive hands-on experience in the use of state-of-the-art instrumentation for environmental analysis. To provide the necessary instrumentation for this program the Chemistry and Biology Departments are establishing a laboratory with an HP 6890 gas chromatograph/HP 5973 mass selective detector tandem, and Lachat Ion Chromatography unit, powerful instruments for environmental analysis. A set of laboratory experiments that adapt active learning pedagogies are being developed within the different disciplines to provide students with collaborative, hands-on experience using the new instruments. The benefits of this project extend to students from all science disciplines, strengthening the links between the Environmental Concentrations in Biology, Chemistry, Earth Sciences and Geography, and Environmental Management. This project benefits faculty development by catalyzing the adoption and implementation of enhanced laboratory curricula, incorporating active-learning pedagogy, and thereby energizing the present undergraduate research program. Furthermore, this project advances teacher preparation by improving the laboratory skills and understanding of current technology for preservice teachers in chemistry and biology, as well as in-service teachers supported through the Bridgewater State College Watershed Access Lab Professional Development program. Evaluation is being conducted by an expert in environmental programs to assess the effectiveness of the hands-on lab in improving student learning and interest in the subject. The results of the development of the new laboratory experiments are being reported at seminars and workshops and in the relevant journals. They are also being posted on the websites of the various disciplines involved.
