The document discusses several models of curriculum design, including subject-centered, learner-centered, and problem-centered models. The subject-centered model focuses on content divided into academic subjects. The learner-centered model places the student's interests and experiences at the center. The problem-centered model organizes curriculum around solving real-world problems. The document also examines Taba's inductive model of curriculum development, which starts with teachers designing specific teaching units before building up to a general design.
