The aim of this study was to find answers to how self-regulated learning (SRL) and cooperation learning orientation correlate with study success. At DSV, a department of Stockholm University, a web based support system for students’ thesis writing referred to as SciPro was implemented. The system also allowed for statistics of thesis process. Through the SciPro system we were able to retrieve students and supervisors; data were retrieved from 45 supervisors and 47 students with regard to their respective responsibilities in the thesis writing process. Vermunt’s instrument, Inventory of Learning Styles (ILS), was employed to measure students’ SRL. Overall, the relation between SRL and completed thesis was not as strong as expected.
