yup, no need at all
for computers in a school, outside of specific IT lessons. hell i'm a professional developer with a software engineering degree, and i never had access to computers at home(does a spectrum count?), or outside of GCSE IT lessons where we used acorns.
when we had homework that involved looking things up, we actually had to go to a library, one was conveniently provided by the school, and look at books. i think the school library had a windows 3.1 pc with encarta on it, but that was the extent of computerised learning.
if i were a teacher i'd specifically search wikipedia for incorrect info and then set an assignment on that subject, happily failing anyone who parroted the wiki info, does that make me evil?
