At 22 March a brainstorm meeting was organised with all team members. The project
team is quite multidisciplinary, which was appreciated by all participants:
- Jeroen Donkers, Jean van Berlo: Knowledge engineer, data scientist
- Arno Muijtjens: statistician, psychometrics
- Danielle Verstegen and Bill Wrigley: educational scientist
- Guido Tans: study advisor
- Robert Peperkamp, Peter Bex, Eric Sol: developers
(Erik Sol
and Peter Bex are hired from CaseBuilders. They developed the user interface of the
ProF system and will, during this project, make some changes to the system to
collect usage data.)
Expected usage patterns
During the
meeting we discussed what usage patterns could exist for students and what
factors can influence those. We
distinguished the following usage patterns:
- Quick orientation (look at the main page and browse through a few details)
- Study the profiles (look at the momentary scores for all categories or disciplines at different points of time).
- Search for issues (systematically browse through all categories and disciplines)
- Look at test-making strategy (look at different score-types: correct-score, questionmark score)
- Look for knowledge development (use the cumulative scores, compare different background populations).
Factors
that could influence the use of these patterns are:
- What is at stake for the student. (For some students progress test is a bottle neck at the end of the bachelor and threatens to prevents them to enter the master. Those students will use ProF much more seriously than others.) This factor is important, and can be computed from previous progress test results. The rules, however, differ per university.
- The study year of the student
- The level of the student (we take the score of the student at the progress test)
- The medical school
A
complication factor is that sometimes a student logs on to the system together
with a study advisor or mentor. In this case, usage will be quite different
from normal usage. It will be difficult to filter out these occasions.
Next to
looking at usage patterns during a session, it is interesting to know how often
and when students use ProF.
We
discusses also that we could also look at the usage patterns of staff members.
Finally, we agreed that the usage of the accompanying website at prof.ivtg.nl. I worthwhile to investigate, using standard web analysis. The problem then is that this website is public so we cannot link it to individual students.

Technical issues
With the
technical subgroup (Robert, Peter, Erik and Jeroen) we discussed how we could log
the usage in such way that these patterns can be studied. For this, we have to know which student during
which session views at what point of time what pages with what options
selected.
Possible
options are to use the web access log, to create a special table in the ProF
database, to use CAM schema. We decided, however, to look into the open source
web analytics tool Piwik. It
appears feasible to link the ProF application to Piwik. The advantages are that
the logdata is separate from the ProF application, that Piwik allows for
user-defined data (such as the user-id we need for linking to progress test
data), that Piwik offers a dashboard and API that we could use, in future, to
visualize patterns to students and staff. We decided to perform a desk research
and to discuss the findings in the first week of April.
Future directions
During the
meeting we also looked forward to future directions. An important concern is
that usage data alone is not enough to know why a student is using ProF in a certain
way. Interviews and observations (with think-aloud protocols) with students and
study advisers would be needed to find out more about this. Moreover, to
measure the effect of using ProF in a certain way needs longitudinal study. The
patterns that we hope to find in this project might help us to set up detailed
research projects.
The results of this project could also lead to changes in the ProF system itself. If it appears that some pages are never used, we might decide to remove those. It could also mean that the instruction of using ProF has to be improved.
We also
speculated at how results might be presented to users. For now it is very
unclear how students could profit themselves, but Guido indicated that he would
very much like to see the ProF usage pattern of students that visit him about
progress test problems.
