Project-based multimedia learning involves students creating multimedia products that address core curriculum topics over an extended period of time. It has seven key elements: being based on core curriculum, relating to the real world, taking an extended time frame, involving student decision making, collaboration, assessment of learning, and use of multimedia. Benefits include motivating students and helping them develop hard skills like problem solving as well as soft skills like collaboration and presentation abilities. Potential disadvantages include needing time for orientation and making sure students have the necessary computer skills.
