This booklet is designed to help educators in Catholic schools integrate the teaching of justice and peace education into the elementary school curriculum. Chapter I deals with the nature of justice and peace education, its basis in Catholic teaching, special considerations for teachers, the need to begin such teaching in elementary schools, and the need for a global approach. Chapter II deals with implementing faculty development and includes suggestions for inservice education and faculty development resources. Chapter III is divided into two sections, one dealing with curricular approaches and the other with special opportunities. Curricular approaches include the addition of subjects, units, or lessons; the infusion method, which concentrates on student activities; and the integration approach, which includes opportunities for justice and peace activities throughout the school's activities. Special opportunities include teachable moments; awareness activities such as worship, speakers, and days of awareness; service projects; and family involvement. Resources for each of these approaches are included. Chapter IV is designed to assess the school's progress as a peaceful and just institution by critiquing learning materials and examining school structures. Appendices include a discussion of justice and peace concepts and a list of resource organizations. (IS)
