David P. Ausubel

David P. Ausubel was an educational psychologist known for his theories on meaningful learning. He believed that learning is most effective when new information is connected to what learners already know, rather than just memorized. Ausubel emphasized the importance of prior knowledge and introduced tools like advance organizers—concepts or summaries that help learners understand new material more deeply. His ideas have influenced teaching methods by encouraging educators to relate new content to students' existing understanding, promoting more effective and lasting learning experiences.
