Creating Parametrized User Modeling Algorithm
To overcome the shortcomings of the CUMULATE's legacy user modeling algorithm, a new parametrized version of it has been devised. A set of studies is set up to evaluate the new algorithm as well as its adaptability/adaptivity.
Study 1
This study involves retrospective comparative evaluation of the CUMULATE's legacy and parametrized user modeling algorithms. The evaluation is done using usage logs collected from 6 Database Management courses offered during Fall 2007 and Spring 2008 semesters at the University of Pittsburgh, National College of Ireland, and Dublin City University. Each course had roughly the same structure and an identical set of problems served by SQLKnoT system.
Scenario
Legacy CUMULATE algorithm and 3 versions of parametrized CUMULATE algorithm. The versions differed in the parameters used for user modeling.
- First, was an attempt to shadow the legacy algorithm by guessing the best parameters for modeling, without discriminating individual user and problem differences.
- The second version, did not discriminate users/problems as well, but the parameters were obtained by fitting the
