The tragic deaths of 26 people shot and killed at Sandy Hook Elementary School in Newtown, Conn., included 20 young children and six educators.Many more children might have been killed or injured had it not been for the brave and decisive actions of the teachers in the school. The mainstream media was quick to call them heroes, and there is little doubt that what they did under horrific circumstances reveals not only how important educators are in shielding children from imminent threat, but also how demanding their roles have become in preparing them to negotiate a world that is becoming more precarious, more dangerous - and infinitely more divisive.

Teachers are one of the most important resources a nation has for providing the skills, values and knowledge that prepare young people for productive citizenship - but more than this, to give sanctuary to their dreams and aspirations for a future of hope, dignity and justice. It is indeed ironic, in the unfolding nightmare in Newtown, that only in the midst of such a shocking tragedy are teachers celebrated in ways that justly acknowledge - albeit briefly and inadequately - the vital role they play every day in both protecting and educating our children.
