This document discusses two major models of curriculum planning: the Tyler model and the Taba model. The Tyler model focuses on answering four fundamental questions to shape curriculum, including goals, content, learning experiences, and evaluation. It provides an easy step-by-step process but lacks feedback. The Taba model takes a more inductive and teacher-focused approach, starting with diagnosing student needs and having teachers develop curriculum. It emphasizes the specific needs of students but teachers may not understand connections between elements. Both models aim to provide guidance for curriculum planning and development.
