Hypermedia-based support for cooperative learning of process knowledge

2000 , Wang, W. , Haake, J.M. , Rubart, J. , Tietze, D.A.

The WWW makes learning materials widely accessible and provides an environment where people can learn across time and space. However, the simple read-only information structure on the Web provides little or very limited guidance to learners, especially when they want to learn how to do something through interaction with computers and other people. We suggest overcoming the problem by introducing a graphical hypermedia-based process representation and a cooperative process enactment support. The hypermedia-based process structure is accessible on the WWW. It contains a rich set of associated materials with which people can seamlessly interact while they are systematically carrying out the process they are learning under the guidance of computers or tutors. A hypermedia-based process support system and two use cases are presented. The use cases show that such a system can not only provide traditional learning support, but also offers novel cooperative hypermedia based support for the learning of process knowledge.

Visualizing and interacting with hypermedia-based process-centric enterprise models

2003 , Wang, W.

Interoperability and cross-fertilization of multiple hypermedia domains are relatively new concerns to the open hypermedia and structural computing community. Recent work in this area has explored integrated data models and component-based structural service architectures. This paper focuses on the user interface aspects relating to client applications of the structural services. It presents an integrative design of a graphical hypermedia user interface for hypermedia-based process-centric enterprise models. An enterprise model covers various important perspectives of an enterprise (such as processes, information, organization, and systems). In this paper, examples are given to show that these perspectives are presented better using a mixture of hypermedia structures found in several hypermedia domains. The visualization and interaction design for such hypermedia-based enterprise models integrates many features found in navigational, spatial, taxonomic, workflow and cooperative hypertext domains. A use case is provided to show that client applications based on this design allow users to see and interact with an enterprise model from multiple perspectives. In addition, some' initial user experience is also reported.
