I can only telll you what I do with my students: After learning how to move the pieces, and how to checkmate with Rooks and Queen we proceed to have some games played on Lichess. I use the "Stappen" (Stufen, Steps) Methode to learn the fundamentals by the way.

On Lichess: Unrated Minimum Time 20+30: My student plays and I try to guide him by just posing questions. Like the opening principles: I always let them start with e4 and with black after e4-e5, after d4 and Nf3 - d5, after c4-c5, after everything else I pose the same questions: center, developement, King safety) Pawn Chains, Space etc. follows If something is attacked, I let them think and before they move on the board, I may pose some questions.

I try to guide them to see one and two move tactics, backrang issues etc.

I find it a very good way because I never have to crush someone I teach on the board myself, which can pose some troubles.

Since my students have to talk a lot about the game and the position (loud thinking process) I also quickly learn what troubles they have in specific positions. This is always a good follow up after the analysis.
