From the pictures above this looks like my country coupled with the names I am seeing on the board. Well I am very much happy seeing that bitcoin adoption and teaching is really going globally. However I would suggest to you during your next presentation you should make it more practically to the students for them to see and view how bitcoin looks like, since is a computer class they always expect the class to be more interactive by doing it practical where they could feel and see what they are learning.
Finally, many people know the importance of Bitcoin. We have gone a long a way already but this is not the end. Currently, there are still more countries who are not into Bitcoin yet and that will be the Bitcoin's next target. I can't imagine the Bitcoins' value once all of those countries joined Bitcoin but if I can only guess then maybe Bitcoin will be hovering at $800k up to 1 million dollars already 
.For starters, what the OP did may be enough already but once the students gets familiar with the basics maybe that was the time for the OP to upgrade his teaching materials although I think this is also costly but if we can be able to donate some BTC's to him then why not?
