For this particular topic (I/O), we have not been able to find
any literature discussing assessment instruments, evaluation, or
classification of exam questions. However, relevant literature
in other topic areas confirms the importance of such work.
Dean and Rodman [6] stress the importance of designing tests
with both algorithmic and conceptual problems in order to
be fair to all kind of students, while Swart [7] remarks that
academics must produce effective questions in order to engage
students in higher order cognitive processes. Although the
work of Dean and Rodman [6] and Swart [7] was carried
out in the field of engineering, the Computing Education
Research community has also shown an increasing interest in
such research centred in what lecturers do, mostly concerning
programming courses.
