Chemistry (12)This interdisciplinary project is adapting and developing powder X-ray diffraction (PXRD) laboratory modules for use in chemistry, forensic science and pharmacy curricula. The new powder X-ray diffractometer is safer, more versatile, and easier to use than the outmoded instrument that is currently available, allowing its incorporation into several undergraduate laboratories. This new instrument allows the integration of practical PXRD training into two courses in which the technique is currently utilized, as well as incorporation of the technique into five other laboratory courses in the chemistry, forensic science and pharmacy programs over the next three years. Undergraduate summer research students under faculty supervision are helping to develop several of the proposed laboratory experiments outlined by performing the laboratory exercises and composing written experimental procedures. Proactive early-stage course development based on evaluation of student learning is being conducted. The knowledge gained from this project is being prepared for dissemination to the scientific community. Undergraduate students who are conducting experiments in these laboratory modules are graduating with a greater understanding of PXRD and its numerous applications.

化学（12）这个跨学科项目正在调整和开发粉末x射线衍射（PXRD）实验室模块，用于化学、法医学和药学课程。新型粉末x射线衍射仪比目前可用的过时仪器更安全，更通用，更易于使用，允许将其纳入几个本科实验室。这种新仪器可以将实用的PXRD培训整合到目前使用该技术的两门课程中，并在未来三年内将该技术整合到化学，法医学和药学计划的其他五门实验室课程中。本科暑期研究学生在教师的指导下，通过进行实验练习和撰写书面实验程序，帮助制定几个拟议的实验室实验大纲。正在开展基于学生学习评价的前瞻性早期课程开发。从这个项目中获得的知识正在准备向科学界传播。在这些实验模块中进行实验的本科生毕业时对PXRD及其众多应用有了更深入的了解。
