The document discusses curriculum design and its types. It defines curriculum design as the purposeful planning of instruction to identify what will be taught, who will teach it, and the schedule. There are three main types of curriculum design: subject-centered, which focuses on teaching a subject matter; learner-centered, which customizes learning to each student's needs; and problem-centered, which exposes students to real-world problems to develop skills. Effective curriculum design considers student needs, sets clear learning goals, identifies constraints, chooses appropriate instructional methods, and establishes evaluation methods to assess student learning and make improvements.
