This week the state Education Department roadshow on the Common Core returns. Commissioner John King will be at Ward Melville High School in East Setauket at 6 p.m. Tuesday, and Mineola High School at 4 p.m. Wednesday, to speak about the curriculum, and to hear concerns. King clumsily canceled previously scheduled forums after a couple of meetings got heated, but the cancellations brought parents and educators anxious to have their say to a full boil. These two are the first of four meetings on Long Island, part of a series of 12 across the state that the department scheduled when it became clear the cancellations weren't going to fly. The meetings will be moderated by state lawmakers, and state education officials say they hope to keep things calm. Attendees certainly need to be civil, but they also deserve to have their questions answered.
