The principle of active involvement states that for learning to occur, students must directly engage with the learning activity or task. This aligns with Froebel's view of self-activity, where learning results from the student's own activity. Students should take an active role in seeking knowledge, such as contributing their own ideas to solve problems, rather than just observing. Educational technology can provide students with various materials to keep them actively engaged in pursuing knowledge. The principle emphasizes involving students in higher-order thinking and activities like reading, discussing, and writing, rather than just transmitting information.
