The document outlines the principles of problem-based learning (PBL) and the phases of the PBL cycle. It discusses PBL as an educational strategy that is student-centered, uses problems to stimulate inquiry-based learning in small collaborative groups, and less contact teaching. The PBL cycle involves students working through tutorials in phases such as defining learning objectives during brainstorming, individual self-study between tutorials, knowledge sharing in the next tutorial, and producing a visual synthesis of learning. Assessment occurs through self-assessment and feedback on the learning process and group work.
