The document discusses child-centered education and problem-based learning (PBL). It states that children learn best when active and engaged in various experiences. PBL consists of carefully designed problems that challenge students to problem solve, develop self-directed learning and team skills, and build disciplinary knowledge. In PBL, students pursue solutions to authentic problems by asking questions, debating ideas, designing experiments, analyzing data, drawing conclusions, and communicating their findings. When using PBL, students develop higher-order thinking skills needed to solve similar problems in the future. Effective PBL problems are selected to accomplish learning objectives, create an appealing storyline, and prompt student curiosity.
