Evaluation of the last grade and attempts in online-learning environment

The purpose of this thesis was to develop models and methods, which evaluated learning in an online environment. In order to reach the research goal, data from tutor-web.net, an online repository containing online lectures and assignments, with questions for various subjects in mathematics, was obta...
