A starting point educationmixed initiative dialogues
Are there educationaladvantages to being able to argue 0 with computer-based tutor about designdecisions?
How might one designan interactive tutor that is able to argue with the student abut designdecisions, does this approach look promising?
The result – WOMBAT amixed initiative system that applied rules to determine what kind of respondingto make to each utterance from the user
Features – dialoguerules that determine which speech acts were appropriate in the current context,stylised sentence construction
Reflection: It worked,did what it was meant to do, but also it didn’t work – no obvious successes,doesn’t actually fit into any obvious educational context
Career path – maths,software engineering, educational technology, agent architectures for dialoguedesign, cognitive modelling, human –computer interaction, studying situatedinteractions and design (distributed cognition, sensemaking, and human error).Shift from formal learning context to more situated learning
Interaction design –puts people at the centre, starts from premise that technology should fitaround the people rather than the converse, need to understand people and howthey are working in order to design effective tools for them
Example – from digitallibrary design to the information journey
People engage with forphases: need, acquisition, interpretation, use
Cycle of informationphases – for example a patient finding out and using information related tosome health issue or students finding information for a course assignment. Informationneed, information acquisition, information interpretation, information use
Supporting sensemakingexamples : interactive visualisations to explore space, richer context tosupport ill-defined searching
Information provisionview contrasts with the lived experience
Resources are beingwasted on inappropriate technologies based on incorrect assumptions about infopractices
A richer understanding of what people isdoing is needed
