Data was collected from students using the ASSISTments online learning system between September, 2012 to September, 2013. Students engaged in various learning activities such as in-class exercises and homework..The data contains 5,801,073 instances with 64 features that summarizes student learning behavior while answering a single problem in ASSISTments. The time duration wherein students answer a single problem varies so most features are aggregated using functions such as min, max or average. Students answer problems in sequence, so it is likely that problems would have answered other problems previously and after it.
