ClassX is an interactive online lecture viewing system developed at Stanford University. Unlike existing solutions that restrict the user to watch only a pre-defined view, ClassX allows interactive pan/tilt/zoom while watching the video. The interactive video streaming paradigm avoids sending the entire field-of-view in the recorded high resolution, thus reducing the required data rate. To alleviate...
Based on existing researches about interaction analysis, this paper designs an interaction analysis coding system to study the level of knowledge construction in web-based interaction. Methods of content analysis and social network analysis are used to analyze the interaction content of a web class on Moodle, which provides a web-based learning platform for a national level excellent course named...
"Web 2.0" refers to a second generation of web-based communities and online services, such as social-networking sites, wikis, and social indexing sites, which enable creativity, collaboration and sharing between users. With the rapid development of “Web 2.0”, network education is changing a lot. In contrast to traditional LMS-driven VLE solutions, PLE based on web2.0 takes a more natural...
The online discussion forum is a common means of learning for CSCL, because participants can share or exchange their understandings, viewpoints, comments, or critiques of a certain task or solving problems with it. The results of analysing the contents of online discussion forums could describe the characteristics of online discussions. In this study, the 20 undergraduate students registered in a...
On-line practice and examination is a new trend of interactive remote teaching and learning. By providing practice and examination content, OPES realizes another distributed and asynchronous learning atmosphere for students. OPES is carried out under the B/S design model with student, teacher, system administrator three functional roles. During the practice procedure, the practice content is focused...
The exploitation of nomenclatures, taxonomies, terminologies and classification of medical diseases, procedures, guidelines has been pivotal to advances in the healthcare domain. Parallel to those have been evolutions in educational technology and medical education where medical educational content is often shared among different educators and institutions. This paper compares the above parallel evolutions...
Semantic Web is the next big thing on the Internet. It implies the general movement towards standardization and machine processable Web information. As a part of this new wave, Microformats appear as the link between present and future Web. They are the lower case semantic Web, dedicated to both humans and machines. We used Microformats in the distance learning center portal for encoding information...
The significance of social presence in asynchronous computer conferencing has become an increasingly important factor in establishing high-quality online learning environments. Levels of social presence exhibited in asynchronous computer conferences influence students' perceptions of learning and satisfaction levels in Web-based courses. Recently, faculty teaching online courses have begun to use...
In order to increase students' capacity of complying with coding standard and strengthen their competitiveness in software industry, an AHP-based evaluation index system and Web-based evaluating platform were established. A student-centered teaching model was discussed, in which both teachers and evaluating platform support the students. After implementing the preliminary teaching model in one academic...
This paper will examine the self-perception and self-representation modes developed by the participants of a 2 year online MEd program in Social, Emotional and Behaviour Difficulties (SEBD), through an analysis of the exchanges occurring on interactive bulletin boards within WebCT. The working hypothesis is that the participants willing to develop a full online persona through the interactive media,...
The theory of communication and information has fundamental applications in our daily life activities. Examples of such applications are: lossless data compression (e.g. ZIP files), lossy data compression (e.g. MP3s), and channel coding (e.g. DSL lines). In this paper we introduce an interactive communication model simulator to facilitate teaching and learning of the basic concepts of the theory of...
