Ben has learned how to ride a tricycle. His parents buy him a two-wheeled bike with training wheels. He gets right on the new bike and begins to ride after practicing using the brakes (which his tricycle did not have). He even comments to his parents, "My trike doesn't have brakes!" Piaget would say that Ben has related his knowledge about how to ride a tricycle to learning to ride the new bike. What has Ben done with his knowledge of bike riding

developed a scheme

Explanation: Schema could be described as a set of acquired knowledge by an individual which is linked together to aid our understanding and view of our environment or world.

In the scenario above, Ben developed a schema for riding bikes which was adopted from his knowledge and experience of tricycle with the only modification being in the brakes which was not in his tricycle. This means Ben has incorporated the knowledge of brake application into his riding schema.
