Hello everybody,
By this time we have used 5 features in classifying the students in one =
of the LON-CAPA courses (PHY183 SS02) for data mining stuff. The goal of =
this classification is to predict the students' final grade from their =
homework sets.
1. Number of correct answers.=20
2. Number of tries to solve the problems
3. Time spent till get the problem correct.
4. Getting the problem right on the first try, vs. those with high =
number of tries.
5. Participating in the communication mechanisms, vs. those =
working alone.
I will try to test two other important features in other courses which =
their activity.log has the related data.
6. Reading the material before attempting homework vs. attempting =
first and then read up on it.
7. Submitting a lot of attempts in a short amount of time without =
looking up material in between, vs. those giving it one try, reading up, =
submitting another one, etc.
Please let me know if you have any suggestion about the features could =
be extracted from the student data or activity.log, which might be =
useful for classifying the students.
Thanks
Behrouz
