This is such a great point, we have these strict safety guidelines in the schools, yet some students may be sharing every detail about their life on Facebook, Twitter or another social media.
But the outcry against intrusions on privacy takes place against a backdrop where it's normal to share a steady stream of details about your life. My concern is that, if we make our schools into places where "normal" means having your browsing history tracked daily, people will take that level of supervision for granted.
try to make some sense about what learning can be within a context where there is a growing tension between constructive guidance and overbearing observation
