Title:
"Evaluating computer assisted learning: what it does and does not have in
common with evaluation in HCI".

Abstract:
For nearly 3 years I have been involved in the huge TILT project in this
university, which is concerned with introducing CAL (computer assisted
learning) in many different corners of the university.  My role is in fronting
the evaluation group.  I thought at first it would be fun to generalise the
HCI evaluation techniques I had.  After a bit I felt that CAL had nothing in
common with HCI, because all the issues were about learning and teaching, and
not about the computer-user interface.  Now I see some commonalities, but only
at a rather abstract level.
	This change in view is to do with a change in what we have found the
usefulness of our evaluations to have turned out to be.  Their main view has
turned out to be to help teachers to modify how the CAL is used within the
context.  So it is really formative evaluation (modifying the design), but not
of the software: but of the overall teaching.
