You make some excellent points.  We expect too much from schools, with sometimes too little cooperation from parents.  I remember the time before so much technology, when teachers sent notes home and called parents at home.  In my view, parents and teachers must communicate; students try mightily to keep that from happening. Now the 'experts' have discovered that fact anew, and we've made a beginning at better communication.  There's a reason to hope we're onto a good thing.
