Linking Experiences: Issues Raised Developing Linkservices for Resource Based Learning and Teaching
No full textMicrocosm is an open hypertext system designed to facilitate a resource-based approach to learning and teaching. In spite of winning accolades the system never established itself as a mainstream educational product. This paper describes the technical and pedagogical features of Microcosm, and attempts to explain the reason for its limited take up. The paper is in the form of a case-study of both good and questionable practice
AnnAnn - a Tool to Scaffold Learning about Programs
No full textIt is difficult for a student to learn about programs and to understand the rational that went into the development of the parts that led to the whole. Tools for explaining this essentially dynamic process are limited and typically static in nature. This paper presents AnnAnn, an animated code annotator which makes it possible to present the development of code to large groups or for self study. The educational benefits of this approach are examined
Microcosm: a hypermedia platform for the delivery of learning materials
No full textThis report describes the Microcosm model and philosophy, and explains the advantages of taking an open, resource-based approach to the development and delivery of learning materials over traditional Computer Assisted Learning (CAL) practices. We describe early experiences in creating materials for the Microcosm environment, paying special attention to the features of the system which make authoring in this way different from traditional practices. Finally, we look at the initial use of Microcosm by students of History and Biology at the University of Southampton
Using Image Content for retrieval and Navigation
No full textMultimedia information collections are becoming increasingly common in the humanities. This paper describes developments in hypermedia and image analysis techniques which are beginning to provide tools for retrieving and navigating through digitally stored visual information. The use of static links for navigating from text has become increasingly popular with the emergence of the World Wide Web, but generic links, based on information content matching can provide more powerful information handling capabilities. We show how content based retrieval and generic link authoring and following can be applied to image data in multimedia collections. The processes at present rely on matching image selections using basic image features such as colour, texture and outline shapes. The paper highlights some of the problems with content based techniques applied to image retrieval and navigation and suggests how the introduction of a multimedia thesaurus could be introduced to overcome some of these problems. The multimedia thesaurus provides a network of concepts in the domain of interest
