Chemistry (12) Two instruments, a handheld X-Ray Fluorescence spectrometer (XRF) and an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) are being integrated into undergraduate laboratories in the departments of Chemistry, Geosciences, and Biology at Trinity University. This integration of analytical tools into undergraduate curricula is helping address three primary goals: improving science and non-science major learning by engagement in interdisciplinary endeavors; improving student depth of understanding of elemental analysis methods; and increasing multidisciplinary interactions among faculty and students which in the long term will fundamentally transform STEM education on the Trinity campus. Project faculty are developing new, engaging laboratories for non-science and science majors that involve hands-on use of these sophisticated, research-grade instruments. The strategy of using relevant (environmental water samples), unique (museum paintings and artifacts), and interdisciplinary samples and problem frameworks (distribution of metals in soils and plants and ecosystems) is intended to better capture student interest than traditional isolated experimentation within a discipline. Elemental analysis methods are being explored at a variety of skill levels across a broad range of disciplines. The impacted courses and programs are affecting a large percentage of female and minority students. This equipment is being used by at least three departments and by two community partners. An outside, experienced consultant is performing formative and will be performing summative assessments of the project. The dissemination plan includes conference presentations, peer-reviewed publications, and web based materials (sites hosted by both Trinity University and the NSDL) that target multidisciplinary audiences.

化学（12）两种仪器，手持式X射线荧光光谱仪（XRF）和电感耦合等离子体发射光谱仪（ICP-OES）正在整合到Trinity大学化学，地球科学和生物学系的本科实验室。这种分析工具整合到本科课程有助于解决三个主要目标：通过跨学科的努力提高科学和非科学专业的学习;提高学生对元素分析方法的理解深度;并增加教师和学生之间的多学科互动，从长远来看，这将从根本上改变Trinity校园的STEM教育。项目教师正在为非科学和科学专业开发新的，吸引人的实验室，这些实验室涉及实际使用这些复杂的研究级仪器。使用相关的（环境水样），独特的（博物馆绘画和文物），跨学科的样本和问题框架（土壤，植物和生态系统中的金属分布）的策略是为了更好地捕捉学生的兴趣比传统的孤立的实验在一个学科。元素分析方法正在广泛的学科中以各种技能水平进行探索。受影响的课程和方案影响到很大比例的女性和少数民族学生。至少有三个省和两个社区伙伴正在使用这一设备。一名经验丰富的外部顾问正在对项目进行形成性评估，并将对项目进行总结性评估。传播计划包括会议演示，同行评审的出版物，和基于网络的材料（由Trinity大学和NSDL主办的网站），目标是多学科的观众。
