The Incorporation of Graphite-Furnace Atomic Absorption Spectroscopy Across the Chemistry Curriculum

化学(12)石墨炉原子吸收光谱仪(GF-AAS)被整合到学院的化学课程中，也被整合到生物系的跨学科课程中。具体地说，在普通化学学期和四门高级化学课程：定量分析、物理化学第二学期、生物化学第一学期和仪器方法这两个学期的新的或修订的实验室实验中都纳入了GF-AAS的使用。此外，项目教员正在开发将GF-AAS用于跨学科生态学实验室课程、全球环境课程和生物系植物生理学实验室课程的实验室实验。正在开发化学和生物课程的实验室实验，特别强调激发学生的兴趣，其中几个实验正在创造学习化学内容的工具，这些内容自然地以伦理适当的方式触及社会正义问题。已经确定并正在评估涉及使用GF-AAS的每个实验室实验的学习和处置结果。该项目有四个主要目标：1)在学生实验室提供真实的化学分析应用；2)在高级化学实验室的新的和有趣的实验中使用GF-AAS；3)在化学以外的学科中使用化学分析；以及4)使化学有趣，即可获得。这些目标与化学系评估其总体承诺的计划中的学习目标相结合，该计划提供严格的课程，为学生未来的科学职业生涯做准备。评估是通过几门课程的概念清单来分析学生概念理解的课程前和课程后的测量。评估还对化学专业学生在本科化学课程中的进步进行了纵向跟踪，以评估在他们的许多课程中使用GF-AAS如何增强学生对GF-AAS技术的兴趣和理解。新的实验室实验正在通过化学教育和生物教育的同行评议出版物以及在NSDL上的交叉张贴进行传播。科学教育方面的研究成果正在通过会议和同行评议的期刊分享。这些实验也通过Perkin-Elmer提供，供使用相同仪器或有兴趣将该仪器的使用纳入其课程的其他机构使用。

Chemistry (12)A graphite furnace atomic absorption spectrometer (GF-AAS) is being integrated across the college's chemistry curriculum and also in cross-disciplinary courses with the biology department. Specifically, usage of the GF-AAS is being incorporated into new or revised lab experiments in both semesters of general chemistry, and four upper-level chemistry courses: quantitative analysis, the second semester of physical chemistry, the first semester of biochemistry, and instrumental methods. In addition, project faculty are developing laboratory experiments involving GF-AAS usage in a cross-disciplinary ecology lab course, a course on the global environment, and the plant physiology lab course in the biology department. The lab experiments for chemistry and biology courses are being developed with special emphasis on capturing students' interest, and several of these experiments are creating vehicles for learning chemistry content that naturally touch on social justice issues in ethically appropriate ways. Learning and disposition outcomes for each of the laboratory experiments involving GF-AAS usage have been identified and are being assessed. The project has four main goals: 1) to offer real-world application of chemical analysis in student laboratories; 2) to use GF-AAS in new and interesting experiments in upper level chemistry laboratories; 3) to use chemical analysis in teaching disciplines other than chemistry; and 4) to make chemistry fun and interesting, i.e., accessible. These goals are integrated with the learning aims in the chemistry department's plan for assessing its overall commitment to offer a rigorous program that prepares students for future careers in science. The evaluation is analyzing pre- and post-course measurements of students' conceptual understanding through concept inventories in several courses. The evaluation is also longitudinally tracking chemistry majors as they progress through the undergraduate chemistry curriculum, to assess how usage of GF-AAS in many of their courses intensifies student interest in and understanding of techniques involving GF-AAS. The new laboratory experiments are being disseminated through peer-reviewed publications in chemical education and biology education and through cross-postings on NSDL. Research results are being shared through conferences and peer-reviewed journals in science education. The experiments are also being made available through Perkin-Elmer for use by other institutions that use the same instrument or are interested in incorporating usage of the instrument into their curricula.
