一种基于虚拟现实的气象灾害逃生演练系统构建

随着虚拟现实技术的发展,模拟真实的气象灾害成为可能。基于虚拟现实技术,构建气象灾害逃生演练系统,通过逼真的气象灾害场景训练,不仅可以提高体验者的兴趣,还能增强其临场感以及面对气象灾害的应急处理及逃生能力。利用计算机设备构建生动逼真的虚拟环境,让体验者拥有身临其境之感,使他们能更方便、更直接地融入虚拟空间,并通过语言、手势、感官等与计算机进行实时交互。与传统逃生演练方式相比,基于虚拟现实技术的气象灾害逃生演练系统优势明显,具有广阔应用空间。

Evaluating a technology supported interactive response system during the laboratory section of a histology course

Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper‐level histology course, the interactive application Learning Catalytics^TM, a cloud‐based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions “on‐the‐go,” engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five‐point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

Research into Practice: Current Trends in Educational Technology Research: The Study of Learning Environments

Educational technology research has passed through a number of stages, focusing, in turn, on the content to be learned, the format of instructional messages, and the interaction between computers and students. The field is now concerned with the study of learning in complete, complex, and interactive learning environments. These environments allow both the simulation of experiences that students might have in the real world and also the creation of compelling experiences that cannot normally be experienced directly. Learning environments also often allow students to communicate their own ideas with the use of a variety of symbol systems. These environments are also frequently inhabited by more than one person, making learning within them a social activity where learning is distributed among both people and artifacts. Finally, these learning environments are complex. Studying how they contribute to learning therefore requires research methods other than controlled experiments. This paper reviews research on learning environments to give both an historical perspective on educational technology research and a selective view of the current state of the discipline. It concludes by identifying implications for both practice and future research.     

远程教育的时间观--从人类学的观点看

通过梳理时间概念的历史,以及借鉴教育人类学对时间问题的研究成果,可以得出这样的结论：远程教育利用其媒体技术创造了一种可以称作为“虚时间”的新的时间形态,这使得远程教育在克服时间距离方面出现了可能,但同时也在师生沟通方面增加了其他难度,     

Developing a virtual engineering management community

The paper reviews the lessons of planning and running an Engineering Management practitioner development programme in a partnership between BP and the University of Manchester. This distance-learning programme is for professional engineers in mid-career experienced in the engineering and support activities for delivering safe, compliant and reliable projects and operations worldwide. The programme concentrates on the why and how of leadership and judgement in managing the engineering of large and small projects and operational support. Two intensive residential weeks are combined with a virtual learning environment over one year. Assessed assignments between and after the residential weeks provide opportunities for individual reflective learning for each delegate through applying concepts and the lessons of case studies to their experience, current challenges and expected responsibilities. This successful partnership between a major global company and a university rich in research and teaching required a significant dedication of intellectual and leadership effort by all concerned. The rewards for both parties and most importantly for the engineers themselves are extensive.

基于虚拟现实技术的企业认知实践教学设计与仿真实验开发

机械类专业学生企业认知学习的目标和任务是使学生了解企业生产和工作环境,增加学生对机械专业工作岗位群的感性认识,并通过理论联系实际初步培养学生的工程意识、工程素质和工程实践能力,为今后进一步学好各门专业课奠定基础。而由于实习学生人数多、学生实习既耽误工作又妨碍生产,因此很多企业都不太愿意接收学生在企业实习,实习企业难找是目前大部分机械类专业面临的共性问题。本论文针对实习企业难找的问题,利用虚拟现实技术设计了以真实存在企业环境为基础的虚拟认知实践教学环境,并开发了可完成仿真实验的数字化虚拟工厂。基于虚拟现实技术的数字化工厂有效解决了学生实习企业难找的问题,为实习学生提供了不到工厂也能参观企业的各个部门及生产车间、了解生产流程、熟悉各类生产设备和工艺的平台。
