I just tell anyone to keep on taking photos and not stop, that's how I learned, went to a class back in high school and learnt all the basics but nothing retained and my photography was unaltered. I began taking interest more later, finding photos that I liked and tried to recreate them, eventually shooting subjects in styles I liked. The needed basics for exposure and settings catch up, then after that, understanding of different cameras and lenses and all the wonders of lighting.
I went to a photography course in University as well, right when I was getting into wedding photography and portraiture, but oh goodness it was a joke, of course all the 101 basics I already knew already, but the instructor was reading out of a textbook just covering all these technical things, even though he talks about his glory days of shooting dozens of weddings. Rule of thirds and interesting subject matter to photograph were covered, but I felt that if I were learning photography from start right there then I wouldn't have learnt anything or improve in it.
Ultimately with anything, self interest and persistent continued effort will lead to success in learning.
Also the two photography teachers I've had in classes NEVER showed any of their own work, only what they found on the internet, so bringing credibility and as a show of experience/knowledge it's good to show your own photos for examples.
I've gone about with people that were interested in photography and just walk through town and take photos of stuff and people, I help them out if they want to take something a certain way, and give (hopefully) useful comments on what I think could work good, or maybe the photo is already good and just let them know that. Sharing and talking about each others photos, what you/others like is important experience for growing, while criticizing too much is often harmful because photography is an art form, and unless someone wants to go pro for a certain field, they just need time, and with a lot of shooting will get to a style and perspective they can feel confident about.
