三维虚拟工作平台应用于高职组装与维护课程教学的研究

针对当前《计算机组装及维护》课程实验教学的不足,结合虚拟现实技术和三维建模技术,论述了三维虚拟工作平台构建的意义和必要性,并根据设计目标给出了三维虚拟工作平台相应功能模块的设计。三维虚拟工作平台可以完成用户与虚拟实验设备的交互,并具有实验考核和实验管理的功能,达到了教学的目标。     

Activity Theory and System Design: A View from the Trenches

An activity theory model and a mediatingartifacts hierarchy were employed to helpidentify the needs for tools for customersupport engineers who documented solutions tocustomer problems, a knowledge authoringactivity. This activity also involves customersupport engineers who assist Hewlett-Packardsoftware product users. The particular toolsto be designed were knowledge-authoring toolsembedded in the customer support trackingapplication suite, SupportTracker. The researchanalyzed the role of tensions between theelements of Engeström's activity theorymodel. The research also explored the benefitsof specific interpretations of Engeström'srefinement of Wartofsky's mediating artifactshierarchy. The hierarchy contributed to theidentification of desired characteristics ofmediating artifacts, particularly tools. Thefindings included an interpretation of the``where-to' artifact concept as supporting anunderstanding of the entire activity system asan evolving entity. Specific interventionswere used to achieve a positive impact on theevolution of the activity system.
