The document discusses different models of curriculum design, focusing on subject-centered and learner-centered approaches. Subject-centered design emphasizes mastery of core subjects through sequential learning and assessment of acquired knowledge. Learner-centered design gathers student interest and career data to create lesson plans, emphasizes active and cooperative learning, and positions the teacher as a facilitator with student involvement comprising 70-80% of activities. Examples of learner-centered activities include projects, presentations, competitions, debates, and educational trips.
