A framework for the development of educational presentation systems and its application

Abstract

In this paper, a framework for the development of educational presentation systems is presented that eases and decouples the development of optional components that contribute to a very basic presentation system. Optional components are introduced in order to support audience response systems, lecture recordings or content sharing using a learning management system, for example. After the presentation of our design goals, we present selected aspects of our framework and the application to our presentation system.

3D Interactions between Virtual Worlds and Real Life in an E-Learning Community

“…(i) An abstract specification of educational presentation systems helps to identify related components and methods, for example, using an object-oriented model [19].…”

Formalization and Verification of a Live Multimedia Presentation Model

“…As mentioned above, the static, linear, single frame-by-frame, and presenter-centered presentation are the characteristics of the popular slideware applications that have been seen by some researchers as the dominant drawbacks of such applications. Therefore many researches and studies have been done to overcome those drawbacks by improving and enhancing the slideware application that finally lead to emerge a presentation system [15][16][18][19][20][21]. Presentation system does not only consider how some slides are made and presented to the audience but it involves how to deliver the detail content of the information to the audience [16].…”

“…Epic considers the quality of views to the audience members through a model. Turban et al [19][20] have proposed and developed an educational presentation system. This system works based on slide model with scenarios.…”

“…Presenter requires delivering the information-content of any multimedia data to the target user through presentation applications with clear and true processes. Meanwhile, the target user has needs and interests to get and to understand such information contents of the multimedia data without any disturbances and noises [19][20]. Those disturbances of the target users' view may come from the confusion between the view of control panel and the video output layout since both are placed in same display or same region window (See Fig.2).…”

“…These functions are purposed for audio channel assigning, where (20) is the left audio channel that is assigned to overwrite the right audio channel and (21) is the right audio channel that is assigned to overwrite the left audio channel. This function is useful to support audio channel removing and balancing such as in karaoke.…”
