How do we promote cognitive development in classrooms using Piaget's theory?

1. Concrete experiences are essential to cognitive development. Provide concrete examples, particularly when abstract concepts are first introduced. 2. Social interaction contributes to cognitive development. Use interaction to assess students' development and expose them to more advanced thinking. 3. Development is advanced when learning task stretch the developmental capabilities of learners. Provide students with developmentally appropriate practices in reasoning that not only matches their current level of understanding, but also encourages them to advance developmentally.
