A new scanning electron microscope is being incorporated into 10 existing courses in a diverse, interdisciplinary curriculum. An environmental SEM with an x-ray microprobe analyzer is being added to enhance teaching and student research programs in electron microscopy, cell structure and function, identification and growth analysis of aquatic microorganisms, and the analysis of structures in chemistry and materials science. An environmental SEM permits easy sample preparation, thus increasing the use of the instrument. The addition of an x-ray microprobe (EDS) creates a complete analytical tool for probing chemical composition and distribution, a particularly important tool for the synthesis and integration of chemistry and materials science. Small laboratory classes permit hands-on use of the SEM by beginning science students and increase science awareness and attractiveness to non-science-majors. The microscope also enhances an existing model program for cooperative service-learning with a local high school for the addition of advanced scientific methods. The course use of the SEM-EDS is expected to increase the use of electron optics in student research, presentations, and publications.

一个新的扫描电子显微镜正在纳入10个现有的课程，在一个多样化的，跨学科的课程。 增加了一个环境扫描电镜与x射线微探针分析仪，以加强教学和学生的研究计划，在电子显微镜，细胞结构和功能，鉴定和水生微生物的生长分析，并在化学和材料科学的结构分析。 环境SEM允许简单的样品制备，从而增加了仪器的使用。 X射线微探针（EDS）的添加创建了一个完整的分析工具，用于探测化学成分和分布，这是化学和材料科学合成和整合的特别重要的工具。 小型实验室课程允许开始理科学生动手使用SEM，并提高科学意识和对非理科专业的吸引力。 显微镜还增强了现有的示范计划，合作服务学习与当地高中的先进的科学方法。 SEM-EDS的课程使用预计将增加电子光学在学生研究，演示和出版物中的使用。
