Ask HN: How to Teach Coding?

I finally did it and I get my first Trainee.

I already teached coding to internships for a few weeks. But this time I have three years to share my knowledge and grow with him.

I already checked methods and stuff online like pair programming, visualization of data flows ect.

But what I would love to know is, what has worked for you guys on both sides. Sharing knowledge and get trained.

I want to be the best mentor I can be and I want to proof that this is a thing I can do good and continue doing it the next years of my career.

So, what helped you to train others or receiving knowledge?
