You will first understand the problem, then make a hypothesis. Players must formulate a hypothesis in the same way as a student in a laboratory. For example, players try different weapons and push themselves to defeat an opponent. If one hypothesis doesn't work, they change the hypothesis and try a different theory or strategy next time. Video games are objective experiences and essential for learning. Schools can even replace tests with video games, suggests Huma Yusuf, author of an article "Video games begin to shape the curriculum." Yusuf says, “Ironically, however, testing is precisely what could limit the use of video games in public schools. Many game designers complain that giving in to the pressure of standardized testing, such as those put in place by the No Child Left Behind law, has forced teachers to emphasize facts, not skills. (Yusuf, Huma) Basically, Yusuf suggests that video games might be the ideal solution for testing because they require confidence, critical thinking, and skills to advance to more difficult levels; It also tracks the choices children make to further analyze their educational attainment. This can work great for tests because students will be competing and trying to get first place, which might require them to use as much information as possible. Students tend to perform better in video games and generally have good grades in school, making them more successful in life overall. Video games are more successful in guiding children and following instructions for better results, which makes them obedient.
