The Engagement Theory is a model for learning in technology-based environments developed by Greg Kearsley and Ben Shneiderman. It synthesizes elements from past learning theories and is based on the idea that students learn most effectively when they find lessons meaningful and are highly interested in tasks. The theory promotes working collaboratively, project-based learning with an authentic focus. Its main tenets are that learning is most effective when students relate through collaboration, create using project-based approaches, and donate by focusing on authentic tasks with outside customers.
