CUMULATE user and domain adaptive user modeling
This stream of work is aimed at improving CUMULATE's legacy one-fits-all algorithm for modeling user's problem-solving activity and creating a context-sensitive user modeling algorithm adaptable/adaptive to individual users' cognitive abilities as well as to individual problem complexities.
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.
