Project-based learning is a teaching method where students gain knowledge and skills by working to design and create a product or presentation. It uses multimedia like text, graphics, video and sound. Key aspects include addressing core curriculum, making real-world connections, extended timeframes, student decision making, collaboration, and assessment. Students learn by creating multimedia themselves rather than just using others' work. Benefits include improving hard skills like problem solving and soft skills like collaboration. It prepares students for skills like planning, presenting information, and applying academic knowledge to the real world.
