Student evaluation (grading) policies are a very important element of any course.  Mostly Indian universities show a tendency to overemphasize the importance of written exams at the cost of several other potential forms of student engagements that require (and hence promote) critical/creative thinking, information gathering, problem formulation, complex problem solving, experimentation/construction/documentation skills,   reflective improvisation, independence of thought, group work, etc. This practice significantly differs from   the practice at CS departments of a few top Universities, e.g., MIT, UC Berkeley, Stanford, etc.

I have tabulated the grading policy of some CS courses at MIT, UC Berkeley, and Stanford University. It can be seen that in 65% of 43 courses, the written exams (including quizzes) do not form the major component of student’s task. Instead   more than 50% weightage is given to student performance in assignments, projects, homework, participation, peer review.  Interestingly,  in 40% courses, there is no midterm/final exam or quiz.  Many midterm and final exams are held as  Open book exams. Some faculty members administer their exams as  take home or open book- open laptop exams.    The faculty members at these universities have the flexibility of designing their own evaluation scheme in their courses.  They do not have to follow a rigid universal scheme in their courses.  Such an academic flexibility is not yet seen on the agenda of academic reforms in India.

In my view,  if any institute wants to excel in computing education, it will have to reform its grading policies as well and give higher freedom to its faculty in terms of designing the evaluation scheme in their courses.   The examples listed below can be used as benchmarks in this regard.   No doubt, the proposed higher flexibility will require a higher sense of commitment for excellence by the faculty members.

Indian Education systems too deserves freedom from overdependence on fixed duration written exams at all levels and in all disciplines. Even IITs suffer from this overdependence. Surprisingly even most young teachers do not show any discomfort from this approach. In my view, this is one of main reasons of mediocrity in our education system.
