The Power of 5E

The 5E Model is a research-based pedagogy that puts the responsibility for learning in the hands of students. Throughout the five stages - Engage, Explore, Explain, Elaborate, and Evaluate - student questions drive inquiry-based learning and help them to build a scientific skill set.

The 5E Model provides excitement and flexibility for teachers and students alike. Kesler Science 5E lessons give students the opportunity to take control over their own learning.
