The document discusses the benefits of learning in virtual world environments. It notes that learning was enhanced through features like social interactions, testing hypotheses, relevance to real world, using multiple abilities and skills, stimulating imagination and creativity, and a sense of presence. Gamification is also discussed, with studies finding that simulation games led to greater learning improvements compared to traditional methods, and that games are a natural way to learn that improves critical thinking. Games are appealing as they provide goals, rules, sub-goals that build learning, and success depends on skill levels. They allow obtaining rewards, failing and repeating, building on knowledge, and controlling time investment.
