Geology (42) Traditional microscopy exercises in Geology often force students into isolation as theystudy minerals, rocks, and textures using individual microscopes. Group interaction is possible, but not easy, as students must take turns looking into classmates' microscopes. An interactive and engaging classroom environment is more conducive to student learning and the development of analytical thinking skills. The intellectual merit of this proposal is to redesign the undergraduate curriculum at Illinois State University toincorporate innovative, inquiry-based learning techniques utilizing polarizing microscope workstations and digital imagery. This project is adapting the interactive mineralogy and petrology program developed at Hamilton College. The goals and broader impacts of the project are: 1) to expose students to modern research and instructional equipment, 2) to enhance student analytical reasoning and problem solving skills, 3) to encourage more students to engage in research utilizing petrographic methods, and 4) to encourage a higher percentage of our students to continue their educations at graduate school, particularly in petrology.In order to achieve these goals, we are establishing digital workstations for polarized light microscopy and image analysis. Each course using the new microscopy digital workstations is developing cooperative learning exercises that are inquiry-based and emphasize critical thinking. Groups of students are working with a microscope and video monitor to deliver a live image. These workstations also are equipped with a digital camera to capture still images for subsequent analysis and are being used for in-class presentations. A Luminoscope for cathodoluminescence work is also being included in classroom activities to expose students to an additional technique for examining rocks and mineral textures. This aspect of the project is adapting strategies developed by Patricia Videtich at Grand Valley State University (NSF-9650073).

地质（42）地质学中的传统显微镜练习通常会迫使学生孤立，因为他们使用单个显微镜研究了矿物，岩石和纹理。小组互动是可能的，但并不容易，因为学生必须轮流研究同学的显微镜。互动且引人入胜的课堂环境更有利于学生学习和分析思维技能的发展。该建议的智力优点是重新设计伊利诺伊州立大学的本科课程，以利用偏光显微镜工作站和数字图像的基于询问的创新，基于询问的学习技术。该项目正在改编汉密尔顿学院开发的互动矿物学和岩石学计划。 该项目的目标和更广泛的影响是：1）使学生接触现代研究和教学设备，2）增强学生的分析推理和解决问题技能，3）鼓励更多的学生利用岩石学方法进行研究，而4个）为了鼓励我们的学生中有更高比例的学生继续在研究生院继续接受教育。为了实现这些目标，我们正在建立数字工作站，以进行两极分化的光学显微镜和图像分析。使用新的显微镜数字工作站的每个课程都在开发基于查询的合作学习练习，并强调批判性思维。一群学生正在使用显微镜和视频监视器来提供现场图像。这些工作站还配备了数码相机，以捕获静止图像以进行后续分析，并用于课堂演示。在课堂活动中还包括了用于致发光工作的发光剂，以使学生了解一种检查岩石和矿物质质地的其他技术。该项目的这一方面是改编由大谷州立大学（NSF-9650073）的Patricia Videtich制定的策略。
