Piaget's theory allows teachers to view students as individual learners who add new concepts to prior knowledge to construct, or build, understanding for themselves. Teachers provide experience-based educational opportunities. Teachers also contemplate the learners' individual qualities and attitudes during curriculum planning. Educators allow learners' insights to alter the curriculum. They nourish and support learners' curiosity. They also involve learners' emotions and create a learning environment in which students feel safe and free to experiment so creative possibilities remain open.
