Chemistry (12) This collaborative CCLI/A&I project is integrating "twin" Rigaku/MSC MiniFlex+ powder X-ray diffractometers into the chemistry curricula at Southern Illinois University Edwardsville (SIUE) and the University of Illinois at Springfield (UIS). X-ray diffraction (XRD) concepts are being incorporated into laboratory experiments that engage students in active learning. Modified courses include forensic science, general chemistry, organic chemistry, instrumental analysis, and inorganic chemistry with the result that approximately 1100 students each year are introduced to XRD techniques through the project. PIs from both institutions are meeting periodically to exchange ideas and resources and to bring students together to share experiences. Student learning objectives include excitement and enthusiasm for science thinking, awareness of applications of scientific thinking, 3-D manipulation of concepts, and improved quantitative reasoning, problem solving, analysis, and synthesis. To address these objectives, implemented experiments increase in sophistication as students progress through the curriculum, and consist of all typical aspects of powder X ray diffraction including peak matching, spacing calculation, symmetry and unit cells, complex pattern matching, peak shape, theory, determining unit cell parameters, and novel student research projects. Educational materials resulting from these efforts are being broadly disseminated through the web-based Nanoscale Video Lab Manual and Nanoworld Cineplex of Movies, http://mrsec.wisc.edu/nano.

化学（12）这个CCLI/A I合作项目将理学/MSC MiniFlex+粉末X射线衍射仪“孪生”整合到南伊利诺伊大学爱德华兹维尔分校（SIUE）和伊利诺伊大学斯普林菲尔德分校（UIS）的化学课程中。 X射线衍射（XRD）的概念被纳入实验室实验，让学生积极学习。 修改后的课程包括法医学，普通化学，有机化学，仪器分析和无机化学，每年约有1100名学生通过该项目介绍XRD技术。 两个机构的PI定期举行会议，交流思想和资源，并将学生聚集在一起分享经验。 学生的学习目标包括对科学思维的兴奋和热情，对科学思维应用的认识，概念的三维操作，以及改进的定量推理，解决问题，分析和综合。 为了实现这些目标，实施的实验随着学生通过课程的进展而增加复杂性，包括粉末X射线衍射的所有典型方面，包括峰匹配，间距计算，对称性和晶胞，复杂的图案匹配，峰形，理论，确定晶胞参数，以及新颖的学生研究项目。 这些努力产生的教育材料正在通过基于网络的《纳米级视频实验室手册》和《纳米世界电影院》（http://mrsec.wisc.edu/nano）广泛传播。
