You should understand the problem first and then make a hypothesis. Players must present a hypothesis in a similar way to students in a laboratory. For example, players try out different weapons and force to defeat an opponent. If one hypothesis doesn't work, they change hypotheses and try a different theory or strategy next time. Video games are goal-driven experiments and are critical to learning. Schools can also replace tests with video games, suggests Huma Yusuf, author of an article “Video Games Are Starting to Shape the School Curriculum.” Yusuf says: “Ironically, however, testing is the very thing that could limit the use of video games in public schools.
