A good education can now be had on YouTube... I have spent the last year learning construction there and the quality of content is excellent. Years ago, I learned to program quite well using online courses and I am sure those have improved even further. I tried to learn diesel mechanics from a textbook That was the top rated in the field, it is shocking how terrible learning from a textbook is.
I am going to have my kids do a combination of apprenticeships and online learning.
Where/what do you teach? When I was doing math & cs - they (especially math) were more than a full time job. Rigor was pretty high - lots of kids failing, dropping out, or transferring schools out. I see this still happening with people I know in school now - mind you not as severe since they’re not in math.
