You have done well OP. This is a catch them young scenario. At this age they can be able to assimilate the bitcoin technology very fast because they are of age and can flow as it is worth learning. Since it was your first time I know the tensed pressure you must have experienced while imparting the bitcoin knowledge on them. Looking at the students, they look eager and interested in the topic and the technology they look aroused and their attention all focused on the teachings.
I believe so too and I am hoping the OP is able to continue on this part with the students and also hopefully will be able to do a demo kind of live teaching with them too. I believe it is another important aspect we don't see people do much outside the theoretical lessons in the class. Let the students see how it is done live from funding your wallet to buying and withdrawing to personal wallets and keeping login info. I know all this can be thought theoretically but it is just one aspect I believe would also help their understanding.
