The purpose of this study is to increase the number of students passing the Java programming course by giving feedback on their online behaviour through a learning analytics dashboard. The treatment consisted of a Randomized Controlled Experiment (RCT) with 556 students, 276 students received for 8 weeks an email with a link to their dashboard and 280 students were assigned to the control group. The treatment- and control group are comparable on the analysed characteristics. There was no significant difference in withdrawal between the control – and treatment group. The results show that offering the dashboard had no significant effect on the percentage passed and the mark of the exam. The analysis of the use of Myprogramminglab showed that the treatment group practiced 5% more than the control group. This result is significant at p= .1 . There was a significant difference between the online use of students of the academic year 2015 and those of 2014. In 2014 the online use was much higher than in 2015.
