An activity-based curriculum is centered around using activities as the primary means for students to learn. It focuses on active, hands-on learning rather than passive reception of information. The key principles are that learning should be based on experiments and activities that engage students directly, as children learn best through doing rather than just listening. The role of the teacher is to guide students and help them select and analyze activities, acting as a facilitator rather than lecturer. Proponents argue this makes learning more engaging, memorable and empowering for students. However, critics note it is a radical departure from tradition and may not ensure retention of facts or cultural heritage.
