This is an interesting and non-trivial question. Which prompts me to
ask - why would you want to track this ?

It is quite possible that many students get conditioned to look at school assignments as 'work', and either try and avoid doing any work outside of the amount specifically committed, or avoid doing anything considered as work outside of the time allotted for 'work'. 

As a corollary, although I do not fancy that Wikimedia is attempting to directly change the way that our education system works in practice, students who treat contributing to Wikipedia/Wikimedia as 'fun' may be better tuned to handling life tasks better/more responsibly in the future. 

Lots of imponderables, I know, but there must be something measurable between students who emerge from school having learned something (and continue to learn happily) and those who only get through examinations.
