项目摘要

The physics program presently supports an introductory laboratory environment which encourages students to design their own experimental approaches to problems and communicate those approaches in an informal manner. Laboratory activities are heavily oriented toward exploratory planning activities with an emphasis on graphical presentation and analysis of data. The student directed experimental design coupled with graphical analysis requires that large amounts of data must be rapidly acquired, and analyzed. To support this need 10 networked micro-computer based data acquisition and analysis systems, together with a variety of sensors, are being introduced in the laboratory. Each micro-computer provides an icon oriented interface (Lab-View) consisting of virtual instruments and virtual probes that may be schematically linked to reflect individual student approaches toward an experimental problem. High level commands allow the students to acquire, display, and analyze data ways which they find most meaningful. The computing environment is sufficiently powerful to include new probes as demand warrants, and thus provides added incentive for more advanced students to attempt alternative experimental strategies. The flexibility in the icon oriented interface also allows the laboratory to gracefully adapt to new experiments and to individual learning styles, thereby enhancing student development of science skills and concept understanding.

物理程序目前支持介绍性的实验室环境，鼓励学生设计他们自己的实验方法来解决问题和沟通以非正式的方式。实验室活动主要面向探索性规划活动重点是图形表示和分析数据学生指导实验设计，图形分析要求必须快速采集并分析为了满足这一需求，10 网络化微机数据采集与分析系统，连同各种传感器，正在在实验室里介绍。每台微型计算机提供一个图标导向界面（Lab-View），由虚拟可以示意性地链接的仪器和虚拟探头以反映个别学生对实验的态度，问题. 高级命令允许学生获得，显示和分析他们认为最有意义的数据方式。计算环境足够强大，新的探头作为需求保证，从而提供了额外的鼓励更先进的学生尝试替代实验策略。面向图标的灵活性接口还允许实验室优雅地适应新的实验和个人的学习风格，从而促进学生科学技能和概念的发展认识
