I really like the idea of proximal
development in the context of educational games. However, I don't think it is just the fact that it provides a
challenge and the ability to learn from failures that makes it so effective.
Growing up with a very traditional and conservative learning environment, part
of what makes it effective and ineffective at the same time is definitely the
stakes that are involved. Many of us are taught at a young age that learning is
our job: our life.
Gammefication takes away that pressure. I know it sounds cliche but it
makes gaming fun. When presented with fun, we're simply more motivated to
continue. After attaining several degrees, the classes that engaged me the most
were the one's that had instructors who went the extra mile in engaging us. Perhaps the most memorable one was playing a
"diplomacy" game while taking my masters in international relations.
It not only cemented some of the more obtuse concepts we learned but also
allowed us to actively apply them without the yoke of evaluation upon our
backs.
