The document discusses Problem Based Learning (PBL) as an alternative model to traditional instruction-based learning. PBL is a student-centered approach where students work in teams to research a problem and develop potential solutions. It outlines the PBL process used at the Republic Polytechnic, which presents students with a real-world problem at their first meeting. Students then conduct independent research and collaborate in teams to define the problem, find resources, develop tentative solutions, and create a presentation of their findings at the second meeting before receiving feedback.
