I agree with my colleagues who argue that it is important to not over-generalise the results of this survey. However, discounting student opinion entirely is not the solution either. The survey as a whole does seem to reflect my experience with students/student essays & presentations over the years both as a TOK teacher, Coordinator and Examiner.
I find it important to refer to school ethos vis-a-vis the treatment of TOK. The more sensible and sensitive students seem to have picked up on this aspect and have duly reflected on the school's/teacher's approach and erudition. I have taught TOK in two schools in the same city in India, and the difference in terms of perception about TOK was/is palpable. It is not surprising then to find that students tend to find their TOK lessons "confusing" to say the least.
