A Networked Classroom for Polarized Light Microscopy to Improve Student Learning in the Microscopic Examination of Geologic Materials

地质学(42)汉密尔顿大学地质学系正在采用“工作室教室”的概念，这一概念已经在其他机构成功地用于教授物理、数学和工程学，以创建偏振光显微镜的网络工作室教室。该项目在支持合作学习的环境中结合了技术的系统使用。“工作室”的特色是由四个岩相学工作站组成的集群，这些工作站被配置成促进学生小组工作。每个岩相显微镜都有一个集成的实时视频馈送，与集群中的计算机联网。教师有一个中央工作站，其中包含传入视频源(每个集群一个)和两个传出视频源(两个数据投影仪各一个)。讲师的工作站用作选择和切换设备，因此来自任何显微镜的实时视频图像可以传输到任一数据投影仪，以便在大屏幕上显示，供学生讨论。该教室使我们能够在几乎所有的课程中革新地质材料微观研究的教学，并引入基于探究的活动、合作学习和小组学习，这些在传统的显微镜实验室中是困难的，在那里每个学生都是孤立工作的。

Geology (42) The Geology Department at Hamilton is adapting the concept of the "studio classroom", which has been used successfully at other institutions to teach physics, mathematics, and engineering, to create a networked studio classroom for polarized light microscopy. The project combines the systematic use of technology within an environment that enables cooperative learning. The "studio" features clusters of four petrographic work stations configured to promote student group work. Each petrographic microscope has an integrated live video feed networked to a computer at the cluster. The instructor has a central work station with incoming video feeds, one from each cluster, and two outgoing feeds, one to each of two data projectors. The instructor's work station serves as a selection and switching device so that a real- time video image from any of the microscopes can be delivered to either of the data projectors for display on a large screen for student discussion. The classroom allows us to revolutionize teaching of the microscopic study of geologic materials in virtually all courses in the Department and to introduce inquiry- based activities, cooperative learning, and group learning that are difficult in a traditional microscopy lab, where each student works in isolation.
