基于“视联网”增强现实技术的教学应用研究

增强现实(Augmented Reality,AR)是在虚拟现实技术的基础上,将计算机生成的虚拟对象叠加到用户所看到的真实场景中,以构造出虚实结合的虚拟空间技术。将虚拟对象无缝的叠加于真实场景中帮助用户加强对环境的理解与情景的感知。文章介绍了当前增强现实技术的有关概念,结合其特点探索了其在教学中的应用。     

虚拟学习社区的自组织性及形成条件

虚拟学习社区具有自发、自管、自调的特点,与自组织理论的基本内涵呈现极强的内在耦合性,如果社区中的学习者建构合理的身份认同与自我效能感、又具有一定规模的参与人数、发表的作品及跟贴达到一定数量、社区中教师具备沟通智慧与反思习惯、社区中的知识权威和意见领袖发挥影响、教育主体之间建立有效的心理契约这几方面满足了耗散结构的产生条件,虚拟学习社区就会出现自组织的特征,由无序走向有序,形成非线性复杂系统。

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,
