"Our students and instructors credit the labs and the CodeLab for improved marks. Learning by doing has helped the students. CodeLab has structured all those things that I have been telling the students to do for their own good. Now that I can check to see whether they have followed through I can reward their efforts." Jeremy Sills, Professor, University of Toronto
"Turing's Craft, in my opinion, is the most important thing that has happened so far in the area of web-based programming instruction." Mike McMillan, Author/Professor.
