I am not aware of any study on using gamification in Asia to improve student performance. The following is based on my observation of college education in Taiwan in Asia.
Gamification can certainly be used as a tool to assist you with encouraging the student engagements. I don't know how effective it will be and how long its effects can last.
Everyone knows that students' motivation is the key reason for students to learn. Gamification will make the game awards to be one of the motivations. You make them learn for the game points they earn. I am not too sure this is a good thing in your environment. There is one difference between Western world and Oriental culture. Gaming is generally considered a not serious good thing. Some students/parents/school officials would resist it. You could get back fire when you use it. You need to be careful. I would use it as the last resort when everything else fails if I were you.
Many Taiwan students attend college because their parents want them to. They are in your classroom not by their own will. They lack motivation to participate in your class. All they want is to graduate to make their parents happy. And then they can do the things they truly want to do.
For those students, I seriously doubt gamification would do any good. I don't believe their parents will be much happier when they see that their kids earn some game points in the classroom. What they truly want to see are degree diploma and good transcripts.
Now, my suggestion as how to encourage the students to learn.
Talk to them to find out what they truly want to do after graduation. Convince them what they learn in your class will be helpful to their future.
For example, many college students in Taiwan want to run coffee shops after they graduate. (Please don’t laugh, this is for real. I don’t understand why either.) As a business professor, you can tell them they need to learn business management so they can run coffee shops successfully.
I have reasons to believe whatever happen in Taiwan may have happened in other places in Asia because the cultures are similar. The problem you are seeing in your area may be different. I believe my suggestion would still be helpful, that is, talk to them to find out what’s the best interest for them. Once you find the root cause, the solution will be right there.
