The teacher is also required to act as a guide, a role that incorporated mediation, modeling, and coaching. One important student role is that of explorer. Interaction with the physical world and with other people allows students to discover concepts and apply skills. Students are then encouraged to reflect upon their discoveries, which is essential for the student as a cognitive apprentice. Apprenticeship takes place when students observe and apply the thinking processes used by practitioners.
Students also become teachers themselves by integrating what they've learned.
Hence, they become producers of knowledge, capable of making significant contributions to the world's knowledge. North Central Regional Educational Laboratory.
