Democracy and the Good School.Building on the success of previous editions, theEighth Edition addresses hot issues such as school improvement, constructivist teaching, professional development, Chaos Theory, and state-mandated standards. This is a resource that students purchase, use in class, and reference throughout their careers as education leaders.
