A progressive content distribution framework in supporting web-based learning

Abstract

Web-based learning offers many benefits over traditional learning environments, where it eases auto student-tracking, active content updating, in addition to provide a time, class size and geographical location independent learning platform to students. In recent years, many web-based courses and educational applications have been developed. In particular, the incorporation of 3D content in web-based learning systems allows students to visualize various types of complicated structures or certain difficult conceptual ideas. This eases the learning processing of students. However, as the volume of 3D content is generally much large in size than traditional textual and image based information, a smart content distribution strategy should be employed to fit the limited resources condition of general users. In this paper, we propose a progressive content distribution framework to support web-based learning using 3D content. We also present two prototype web-based learning platforms. © Springer-Verlag 2004.
