This document discusses problem-based learning and project-based learning. Problem-based learning involves teaching students through problem solving, having them work in groups to analyze problems, research solutions, and present their findings. Project-based learning focuses on having students complete a project, requiring them to organize their own work, research, and collaborate with others. Both approaches engage students and teach useful skills, but problem-based learning emphasizes critical thinking while project-based learning promotes group work and time management skills.
