“…To this end, e-learning systems must be designed and constructed cautiously, especially while applying a scientific approach with well-designed procedures and techniques. The ultimate goal is to accomplish an effective and high quality learning system, comparable with the traditional educational systems (Colette, 2001). Web sites appear as the primary interface to the end user (e-learner) and user satisfaction vis-à-vis humancomputer interaction determines the quality of the elearning provider.…”

High quality web site has been generally recognized as a critical enabler to conduct online business. Numerous studies exist in the literature to measure the business performance in relation to web site quality. In this paper, an axiomatic design based approach for fuzzy group decision making is adopted to evaluate the quality of e-learning web sites. Another multi-criteria decision making technique, namely fuzzy TOPSIS, is applied in order to validate the outcome. The methodology proposed in this paper has the advantage of incorporating requirements and enabling reductions in the problem size, as compared to fuzzy TOPSIS. A case study focusing on Turkish elearning websites is presented, and based on the empirical findings, managerial implications and recommendations for future research are offered.

“…Consequently, the web site quality should be considered as a critical success factor for e-learning service providers. Especially, in the case of vital education or training services, the web site quality and its evaluation should be studied in a more detailed manner from elearners' perspective (Colette, 2001).…”

“…An exception is the four-tier Electronic Educational System (EES) model proposed in [16] that provides limited data personalization to the end user. Specifically, the top layer in the system, known as the instructional layer, allows educators (not users) to specify which media components to include in the system (video, slides, chatroom, whiteboard, etc.).…”

Metadata-driven multimedia transcoding for distance learning

Advances in multimedia processing capabilities of electronic devices and the rapid growth of the Internet have contributed to the proliferation of collaborative applications such as distance learning (DL) webcasting. A key technical challenge in such DL systems is providing access to rich media content to any user regardless of device capabilities, network heterogeneity, and personal preferences. A novel MPEG-21-based adaptation architecture is presented to overcome these challenges by performing (1) application layer transcoding that adapts the presentation format of DL content to match device media decoding capabilities and user-desired modality, (2) bitstream transcoding to adapt multimedia to match device processing capabilities and encoding bit-rate supported by the network. Experimental results indicate that the proposed system delivers personalized DL content to meet end-user environmental restrictions with small transcoding overhead.

Abstract.A neglected challenge in existing e-Learning (eL) systems is providing access to multimedia to all users regardless of environmental conditions such as diverse device capabilities, the heterogeneity of the underlying IP network, and user modality preference. This paper proposes a novel two-tier transcoding framework capable of adapting eL multimedia to meet the end-user environmental challenges. This two-tier architecture consists of 1)an application layer transcoder that adapts the presentation format of the eL content as viewed in a browser to meet device capabilities and user modality preference, 2) a bitstream transcoder that transforms multimedia streams to conform to the device's processing capabilities and to adapt the encoding rate to meet the network's fluctuating bandwidth. Results demonstrate the eL multimedia transcoding for mobile devices and its low overhead delays.
