Editor’s Note: Today we announced the full availability of Microsoft Kodu Game Lab for the PC and the launch of a nationwide Kodu Cup competition. We’re inviting students, aged nine to 17 to design, build and submit their own video games. The following is a guest blog post about the educational benefits of video games and video game design from Gabrielle Cayton-Hodges, Research Fellow, The Joan Ganz Cooney Center at Sesame Workshop, which specializes in advancing children’s learning in the digital age. There’s a growing body of evidence that both playing video games and making video games have promise as educational tools. In fact, it may be one of the most effective ways to engage today’s youth as they learn the critical skills they will need to succeed. As the Federation of American Scientists concluded from its 2006 Summit on Educational Games: “The success of complex video games demonstrates that games can teach higher-order thinking skills such as strategic thinking, interpretative analysis, problem solving, plan formulation and execution, and adaptation to rapid change. These are the skills U.S. employers increasingly seek in workers and new workforce entrants. These are the skills more Americans must have to compete with lower cost knowledge workers in other nations.” In fact, game-based learning has emerged as one of the most promising areas of innovation in making Science, Technology, Engineering, and Mathematics (STEM) topics more engaging for kids today. The report Game Changer: Investing in Digital Play to Advance Children’s Learning and Health , demonstrates that video games can be used to learn not only content, but also STEM skills and systems thinking, which are essential for preparing youth for STEM careers.
