How to propose alteration of study subjects in college?
In the comments, you explained that you are currently a student. I would suggest you have a friendly conversation with your professors. Perhaps you know your advisor a little bit, or one of your professors from your class and you're comfortable talking to her or him. 

For example, let's say you decide to talk with Professor Smith. I would go up to Professor Smith (e.g., during office hours) and say: "Hi. I had a cool internship at Gaming, Inc. I learned some interesting programing methods X, Y, and Z" (follow their interest in their methods here, you might end up deep in details or your professor may not care). Then ask something like "We haven't covered the methods in my classes. I think they would help other students in our program. Are they included anywhere in our curriculum?" 

This will start a conversation with your Professor about the curriculum. Most reasonable professor will be open to your conversation, just don't put them on the defensive. For example, avoid saying something like "our program sucks..." or "you should do...". Also, keep your suggestions positive and avoid being arrogant. Perhaps your program is revising their curriculum now and you do not know about it.  

As an aside, I had a similar experience as an undergrad wildlife biology student. During a summer internship, I worked for a government agency using management approaches not covered in class. I asked a friendly professor why we were not learning the topic during an informal office hour. The friendly prof said a couple of reasons (basically their curriculum had not been updated) and then another, crotchety old professor jumped in and though my idea was stupid (he was dinosaur who did not like change). The friendly professor actually changed his view point and started defending my question/view-point. In my case, I was not able to change the curriculum, but I did learn why it was what it was.
