In these increasingly rootless and spiritually vacant times, high school students, living through the difficult years of adolescence, have much to gain from Catholic schools, including the opportunity to learn and identify with a venerable religious and moral tradition. This 10 chapter guide outlines the various aspects of teaching religion in Catholic secondary schools. The chapters cover why teach religion; what should be taught; values; dealing with controversy; developing skills; teaching strategies; materials; assessment; occupational hazards; and a developmental perspective. A 9-item bibliography is included. (DB)
