An experience with an enriched task model for educational software

The educational domain brings new issues and specific requirements to interface design. Often traditional HCI principles and guidelines need to be disregarded or broken in order to allow for the intended learning to take place [1, 6]. How to adapt existing HCI methods and techniques to this domain is still an open issue for the HCI and Education fields [5]. In this paper we propose the Scaffold Representation Model (SRM), which allows intended educational support for learners in the application to be abstractly described. The model allows for the generation of educational information that can be added to a traditional HCI task model. We describe an experiment in which SRM was used in the design of a learning support system and its contribution to the process of design.
