Taking a Bitcoin class to educate others is a good thing to do out of having passion for others to have a means to learn about Bitcoin especially those in the rural setting but from what I can see on the pictures displayed by OP, am not convinced enough that this actually had to be a Bitcoin class because nothing here is showing or speaking about Bitcoin than the traditional dance held during on local community gathering, moreso much of this kind is getting too common from newbies these days.
Maybe, they have some extra fun during the class. We can't judge what truly happened in that session.
However, I am with the side of
lovesmayfamilis, the OP is also a beginner himself. So he might give a different impression about the market.
Should be upfront that this market needs good understanding before they can start to trade. This may give them false hope of earning tons of money.
The OP should advice them to start small if they want to test the market. There's a lot to learn before they can truly earn something.
But let's say, this is a good start. Only few of them will push thru the actual trading. I hope the OP didn't give them the hope that this is their way out to poverty.
