I recently learned of an experience where a tap by a teacher with a pointer on the back of a student laying across a table as the student conferred with a friend was labeled a hit by administration. After a quick search (more needed of course), it seems that school systems and teachers prefer a "no-touch" policy (See Armatage Elementary in Minneapolis). For me, this issue of human contact is part of our social nature. In fact, as infants there is strong evidence to suggest that audio only or video only tools are useless to infants learning a language (See Aspen Ideas 2009 Festival - Brain Development). Languages are learned through interaction between caregivers and infants. In my own experience, I remember facts from experiences including a social element better than other methods. Is a "no-touch" policy good for learning?
