Acton and the Learning Pyramid (Retention Rates for Learning)

The Learning Pyramid suggests different teaching methods impact knowledge retention differently. Attributed to the National Training Laboratories (NTL), it claims passive methods like lectures result in lower retention, while active methods like teaching others lead to higher retention.


According to the model, students retain 10% of what they read, 20% of what they hear, and up to 90% when they teach others. This has been used to advocate for interactive learning.


Supporters of the Learning Pyramid argue that it highlights the effectiveness of experiential learning, where students engage more deeply through hands-on activities and collaboration. Many educators use it as a guide to design more engaging and student-centered curricula. The model also emphasizes the role of teaching as a powerful learning tool, reinforcing the idea that explaining concepts to others enhances understanding.


However, critics argue the retention percentages lack scientific backing. Learning is highly individualized, influenced by prior knowledge and engagement rather than a fixed hierarchy.
Despite these flaws, the pyramid highlights the importance of active participation in learning. While its figures are questionable, its core message encourages diverse teaching strategies to improve education.


This aligns with the learning model of Acton Academies, which emphasizes self-directed learning, Socratic discussions, and hands-on projects. Acton’s approach mirrors the Learning Pyramid’s advocacy for active engagement, where students learn by doing, collaborating, and teaching others, reinforcing deeper understanding and long-term retention. So while the pyramid is not precise science it does highlight why the Acton model is so empowering and meaningful to so many learners!
