Planning is the process of thinking about activities to achieve goals and involves instructional and time planning. Effective planning considers subject matter, learners, context, and the teacher's role. It develops systematic time plans focusing on tasks and timeframes like pre, during, and post instruction. Useful teacher-centered planning tools include behavioral objectives, task analysis, and instructional taxonomies like Bloom's taxonomy. Direct instruction is a structured teacher-centered approach with teacher direction, high expectations, maximizing academic time, and minimizing negative impacts. Learner-centered approaches involve the teacher as a facilitator with methods like cooperative learning, discovery learning, role-playing, scaffolding, and problem/inquiry-based learning.
