The idea that little children are continually coming up with ideas and testing them is called "constructivism." This educational theory, often associated with Jean Piaget, suggests that children learn through active exploration and experimentation. They construct their understanding of the world by interacting with their environment, solving problems, and reflecting on their experiences. This hands-on approach fosters cognitive development as they refine their ideas and learn from their mistakes.
