How we quantify institutional change.

Our measure of the incorporation of IT-based teaching material into our courses is the

Directed Information Technology Time (DITT)

This is the number of hours within the timetable of a course in which conventional teaching has been replaced with IT-based teaching. It does not take into account the number of students involved, the number of staff involved, or any circussing arrangements. It provides a very conservative estimate of the IT-based teaching going on in any course and does not include non-timetabled activities. However, in order for IT-based material to be timetabled, it must replace conventionally-taught material, and hence DITT gives a good measure of institutional change within our members' departments.

We measure the amounts of supervised and unsupervised DITT in both tutorial-type teaching and practical class-type teaching. The results are summarised below. Note that the figures for 1991/92 represent the situation before the BioNet project started. Click on each chart. The third and sixth contain the key to all of the charts.


How we quantify productivity gains.

We have collected information on the DITT within more than 80 of our members' courses in the biological sciences and preclinical medicine. We can use this information to calculate:
