ABSTRACT In this presentation, we demonstrate different mechanisms for the contextualized integration and navigation of video in Web based hypermedia spaces for learning environments. KEYWORDS Interactive video, hypervideo, integration in context, navigation, cognitive processes, e -learning.
1. INTRODUCTION Global access to information and technology changes the relationship between people and knowledge. Significant technological advances and the new tendencies for media convergence and integration are transforming video into a dominant medium, suggesting new ways to support learning activities. Visual presentations have always been an essential aid in learning environments. Video has been used to provide students with authentic learning experiences, something constructivists have strongly argued for, showing students that learning can be exciting and intellectually rewarding. Furthermore, videos can be complemented with other materials, like text and images. However, effective reflection, and thus learning, requires more flexible mechanisms to manipulate the multiple affordances of the media at hand.
2. APPROACH AND DEMO Interactive video hyperspaces are based on hypervideo technology, providing the mechanisms to structure, navigate and interact with rich multimedia information spaces. It improves the understanding of the message conveyed by different media, due to the contextualized explanations and illustrations made possible by the integration of different materials. Important relations with the video information can be captured. It is easier to search for information and to capture the videos’ messages, through the different indexes and maps available. Hypervideo structures provide the open and flexible integration of the multiple media, adaptable to learning styles and learning situations. In this presentation, we demonstrate different mechanisms for the contextualized integration and navigation of video in Web based hypermedia spaces for learning environments.
