This document defines key terms related to curriculum and Christian education. It discusses curriculum as including the recommended, supported, taught, tested, learned, and hidden aspects. Christian education is understood from four perspectives: religious instruction, socialization, personal development, and liberation. Formal, nonformal, and informal learning environments are also addressed. The curriculum design process involves defining instructional purposes, goals, outcomes, scope and sequence, and methods based on educational foundations. The resulting instructional plan guides the creation of curricular materials for teaching.
