This document discusses project-based learning and its importance in education. It notes that project-based learning has students explore real-world problems and challenges with the teacher serving as a facilitator. Research shows it can be more effective than traditional instruction for academic achievement, long-term retention, and skill development. In the 21st century, project-based learning enhances students' technology knowledge as they use tools like virtual worlds, PowerPoint, wikis, podcasts, and webquests for their projects instead of traditional posters and papers. These tools promote collaboration and allow students to explore topics in more depth.
