Providing Better Feedback for Students using Projekt Tomo

Systems for automatic assessment of programming tasks have become a popular choice in programming courses as several advantages of using automatic assessment in teaching and learning process have been observed. One of the most important is the immediate feedback students get. However, the quality of the feedback is essential to achieve good learning results. At the University of Ljubljana we use our proprietary system called Project Tomo as a teaching tool. One of the most important aspects of our system is the possibility to return a detailed feedback and to analyze the student’s solution since every submission is stored on the server. Until now we have collected more than 110,000 attempts along with their history. We are currently in the process of analyzing them. Currently we are concentrating on how to use this data to further improve the quality of the feedback given to the student. Some of the observations and the preliminary results are presented in the paper.
