Over the past several years, gamification has become a buzzword, used in everything from driving engagement at conferences to use cases in e-learning. Gamification helps in e-learning because it allows you to leverage the competitiveness to make training more dynamic. Over the years, researchers have identified how the interactive learning process benefits humans and how it can be implemented in teaching. Part of that process has evolved into using gamification in e-learning. Gamification in learning can be explained as implementing the gaming elements like the point system, badges, leader boards, awards, and graduating from one level to the other in a non-gaming environment.
