Self-access modes of learning can be encouraged by requiring students to find additional related information on the internet and attach their findings to the media by annotation, and to include an explanation on the relevance of their discovery. The components of a modular framework to support web-based lessons are illustrated in Figure 1. Defining and adopting a framework allows individual components to be upgraded without affecting the overall system. The components include the following. Content Delivery - this component provides the visual interface and media delivery.
Content is delivered using video, audio, images, text, and animation.
The visual interface includes links to the other framework components and the Chat window. Quiz - this component allows teachers to create and maintain a database of questions. Students can request quizzes and self-tests from this database. Annotations - this component provides the ability for students to annotate web pages hosted on local servers. Students can attach their questions directly to the item they wish to discuss.
