Why are you interested in game elements? What experience do you have with gamifying learning?

Currently I work as a graduate professor at Universidad Metropolitana in Caracas Venezuela. My area of ​​interest is the evaluation of knowledge, and I am very interested in learning about the application of game elements in the learning process, particularly in the evaluation process.
I have no previous experience beyond a few trials in this area, but so far nothing formal.
I am very interested in designing a course utilizandoi achieve these elements of the game. I hope to do soon.
