This document provides an overview of alternative learning systems in the Philippines. It discusses non-formal education, informal education, and the mobile teacher program. Non-formal education occurs outside the classroom, while informal education focuses on practical skills. The mobile teacher program targets learners in remote areas by having teachers travel to conduct classes. The document also provides ways to make these alternative learning approaches more learner-centered, such as using flexible seating, learning stations, active learning strategies, and technology integration.
