The Pinellas County school district will broadcast a 75-minute video to explain the Coalitions of Schools for Student Success. The coalitions have been proposed as part of a plan to change the desegregation plan in Pinellas County public schools. The coalitions would group schools so they could trade information and tactics to help improve student learning. The video will be aired at 8:30 p.m. Monday, Thursday and Friday; at noon Tuesday; and at noon and 8:30 p.m. Wednesday. The broadcast will be televised on Vision Cable Ch. 5, Paragon Cable Ch. 14, TCI Cable Ch. 20 and UHF Ch. 14.
