职业教育主要为企业培养技能型人才,模具的拆装实训在职业学校的模具教学中非常重要。因学生人数多,实物昂贵,实验课时数少,学生做实验的次数有限,大大影响了教学效果。虚拟实验系统由于其不受时间和场地的限制,在实验实训教学中起到了非常好的辅助作用。该研究利用Virtools等软件开发工具开发虚拟冲孔模拆装虚拟实验系统,该实验系统按照实验介绍、实验室漫游、虚拟实验和实验报告四个功能模块进行设计,其中虚拟实验模块包括自主分解和分组装配两个子模块部分。软件开发过程主要包括:素材的准备、冲孔模模型的构建、在Virtools中实现模型的交互等。 相似文献

This paper presents empirical results from an exploratory study conducted in an authentic educational situation with preservice education students enrolled in an undergraduate course, which was partially taught in Second Life. The study investigated the effect of environment design on presence, learning outcomes and the overall experience of the students. Two different educational virtual environments (a traditional university auditorium and an open‐air setting) were designed and presented to different groups of students (n = 51). Results indicate that students' experience from the educational activities, their attitudes toward the environment and the induced sense of presence are not affected by the design of the educational setting. Learning outcomes seem to be slightly better in virtual educational settings that replicate traditional educational settings. Experience shows that undergraduate university classes can be successfully taught in Second Life and such environments elicit satisfaction, positive experiences and attitudes and high levels of social presence from the participants. Course design in a Multi‐User Virtual Environment (MUVE) should take into account the time and training necessary for all students to become familiar with the virtual environment and possible time losses due to technical issues. This study could act as support to construct and test hypotheses regarding the role of educational setting design in teaching and learning in MUVEs. 相似文献

The emergence of new technologies has made it increasingly easy for distributed collaboration in both educational and noneducational settings. Although the effectiveness in traditional settings of the dynamics of small group work has been widely researched, there is limited research that offers evidence on how teams can work effectively in a virtual environment. The purpose of this study is to examine the relationship among team structure, trust, and conflict management style, in addition to their impact on teamwork effectiveness in a virtual environment. An experimental design was used to assess the effects of structure on team performance. Forty‐four groups, divided into hierarchical and nonhierarchical groups, worked on an online simulation project in an online MBA course. The results suggest that team structure is strongly associated with team performance, whereas trust and a collaboration conflict management style contribute to teamwork satisfaction. 相似文献

This article presents a role-play game for software project management (SPM) in a three-dimensional online multiuser virtual world. The Opensimulator platform is used for the creation of an immersive virtual environment that facilitates students' collaboration and realistic interaction, in order to manage unexpected events occurring during the development of a software project. Through the simulation of a real-life company, the game aims to enhance experiential learning of human-related issues, such as project team members’ communication and collaboration, which are not easy to be taught through ordinary teaching methods. Roles are assigned to the participating students, who have to overcome problems initiated by non-player-units (software controlled units) while collaborating with other students and the instructor. The instructor, holding a key role in the game, is able to observe the players, intervene and dynamically alter specific game scenario parameters adapting to player encounter difficulties. The environment is combining the experience of a typical game (based on an event-driven SPM scenario and interaction with non-player-units), with the experience of a virtual world (interacting with other players) and has been positively evaluated by the participants regarding the overall game experience and the learning effect. 相似文献

Small‐ and medium‐sized enterprises (SMEs) play an important role in creating a dynamic and successful European economy. Time‐poor managers in these organisations generally have fewer opportunities for training and development than their counterparts in larger organisations. As a result, different requirements are placed on training. The aim of this study was to test the principles of action learning in a virtual environment. The action‐learning programme was based on virtual working but did also involve face‐to‐face workshops, thus providing a blended approach. The project was designed to be “evaluation‐led”, with evaluation progressing alongside the project from design to finalisation. The focus of this paper is on how the evaluation‐led approach unfolded. To this end, we start by explaining our research approach, we then move on to an analysis of the project to conclude with a discussion of the findings and of the lessons learnt. We conclude by highlighting some further research needs. 相似文献
