Problem-based learning is an approach where students work in small groups to solve open-ended problems focused on real-world scenarios. It follows a 6-stage process where students identify problems, brainstorm, research, synthesize information, build knowledge together, and refine outcomes. Benefits include improved communication skills, self-confidence, motivation to learn, and problem-solving abilities as students explore resources and ideas with peers. Technology allows for online collaboration and tools to support the learning process.
