Again, I feel I ought to define my terms before going any further.
The broadest definition of e-assessment encompasses the use of computers for any assessment-related activity, thus it might include the electronic submission of tutor-marked assignments, the marking of student engagement with a tutor group forum or the compilation and grading of an e-portfolio. I have interests in all of these aspects. However much of work I have done relates to the online delivery and automatic marking of questions, with the provision of immediate feedback, in Open University interactive computer-marked assignments (iCMAs) so this is the area I can speak about with most authority.
