Computer Instrumentation and Visualization in an Interactive Studio Environment: Eliminating the Boundary Between Lecture and Laboratory in Undergraduate Chemical Education

化学(12)该项目正在通过实施一种消除讲课和实验室之间界限的教和学环境，解决本科生在化学科学方面的已知和重大缺陷。在前期工作的基础上，我们正在修改由伦斯勒理工学院和加州理工州立大学开创的工作室-实验室概念，并将美国国家科学基金会-CCLI奖(9951346；9950501；9952732；9972293)中的元素用于我们的分析和荣誉级别的化学课程。这提供了一个教与学的环境，解决了我们的学生在理论和实践之间建立更高层次联系的困难，并改进了他们在定量实验中展示的实验室技术。这一努力的核心是从对“罐头”实验的监督和评估转变为对现实世界问题和实验室技术的探究式研究。许多新的技术特征被纳入我们版本的工作室-实验室，它被分成几个站。每个站点最多可服务四名学生，支持两台计算机和数据接口(游标Lab Pro)和一个二极管阵列UV-Vis光谱仪。每组四个站(一个组)共用一台FT-IR分光光度计。教师作为“专家导师”和“引路人”，提供一个具有丰富的真实世界内容和实验室技术的探究式学习环境。WebCT作为正在开发的教育媒体的门户，增强了教师的能力。点播视频、概念动画和自定进度的学习作业是专门为帮助我们的学生在理论和实践之间建立更高层次的联系而设计的，特别是那些更直观的学习者和那些需要额外加强或支持的人。正在为密歇根州上半岛所有大学和学院的教职员工提供讲习班，以便向大学社区介绍工作室-实验室的概念。还将为高中教师举办更多的讲习班。

Chemistry (12)The project is addressing known and significant deficiencies in the way undergraduate students are educated in the chemical sciences by implementing a teaching and learning environment in which the boundaries between lecture and laboratory are eliminated. Building on our preliminary work, we are modifying the Studio-Laboratory concept pioneered by Rensselaer Polytechnic Institute and California Polytechnic State University, and elements from NSF-CCLI awards (9951346; 9950501; 9952732; 9972293) for our analytical and honors-level chemistry courses. This provides a teaching and learning environment which addresses our students' difficulty in making higher-level connections between theory and practice, and improves the laboratory technique they exhibit in quantitative experimentation. Central to this endeavor is the change from supervision and assessment of "canned" experiments to an inquiry-based study of real-world problems and laboratory techniques. A number of novel technological features are being incorporated into our version of the Studio-Laboratory which is divided into stations. Each station, serving up to four students, supports two computers and data interfaces (Vernier Lab Pro) and a diode-array UV-VIS spectrometer. Each group of four stations (a cluster) shares an FT-IR spectrophotometer. The instructor serves as an "expert-mentor" and "guide" to provide an inquiry-based learning environment rich in real world content and laboratory techniques. WebCT augments the instructor by serving as the gateway to the educational media under development. On-demand video, conceptual animations, and self-paced learning assignments are being designed specifically to help our students build higher-level connections between theory and practice, particularly those who are more visual learners and those requiring additional reinforcement or support. Workshops are being offered to faculty and staff from all universities and colleges in Michigan's Upper Peninsula in order to introduce the university community to the Studio-Laboratory concept. Additional workshops will be held for high school teachers.
