In chapter 10 of my book, I cover the use of computer games for teaching and learning (section 2.2 of the ITGS syllabus). This was one of the hardest sections to write because concrete evidence – either supporting or refuting the benefit of games, is hard to find. For every article suggesting benefits, there seems to be others showing no benefits, or even describing gaming related horror stories.
The infographic How Gaming Affects the Brain from the Educational Technology and Mobile Learning blog outlines the impact of video games on the human brain and makes interesting reading, even if it comes no closer to providing a definite answer about the benefits of gaming.
