Are you a gamer? You probably are whether you know it or like it. In the open, games are competitions between people, groups, organizations or countries. Doesn't really matter, as long as it is a competition. In schools, we compete based on grades. It's a measuring stick and the carrot at the end of the stick is the belief that higher grades equals future success.
This of course, is totally wrong.
Competition should be based on ideas, not grades. In the real world it's your idea that wins over another division, group or company, how much you remember about the process of the idea. Students should be assessed based on their grit, ingenuity and ability to communicate. In the end ideas win the day and being able to teach students how to grow them from conception to reality is the best way we can help.
