An Internet-based e-learning system offers many benefits over traditional learning environments. It provides a time, class size, and geographical location independent learning platform to students in addition to being able to consolidate e-learning content from a vast amount of Internet Web sites and deliver it to students. However, as the e-learning content may be large in data size, students probably need to spend a prolonged period of time downloading the required learning materials. This would likely discourage certain students from using such a learning platform. In this article, we propose a method to deliver e-learning content in an on-demand manner. This allows students to enjoy the benefits of Internet-based learning without suffering the download problem. We also present prototypes of Internet-based learning platforms.
