Brian Cambourne outlines several conditions that are necessary for learning to occur: learners must be immersed in examples of what they are trying to learn; they need to see multiple demonstrations; they must feel empowered and supported to take risks in approximating their learning; and they need opportunities to practice and use their skills. For learning to be successful, learners also need to feel engaged and responsible for their own learning process without fear of negative consequences for mistakes. Engagement is likened to properly engaging a car's clutch - without it, demonstrations and opportunities will not effectively lead to learning.
