Exactly...
We evaluated the final exams, where the students are assigned two
questions, and we graded every step of Design Recipe. Using "R", we
conducted a linear model analysis. R says, template and tests are most
significant, meaning that students who did the template and the tests
properly, also wrote fully functional code.

Or, vice versa :) Since we don't know whether they did the code first
and then the template, test, etc. we want to record every change and
replay the session of the student. This will strengthen our case. Using
this technique I can tag the students submissions according to the
order of the application of design steps, then use this extra
information for the analysis.
