No, that’s just rigorous writing. Rigorous pedagogical approach implies helping other minds to solve problems and obstacles with acquiring knowledge. Your approach results in coincidental learning because you don’t care about the mind of your learners and their problems, you care about your own.
I do suggest to experiment with your writing — try writing only about your own journey (and nothing else!), try sitting down with another person, multiple people, and teaching them the same thing. Try writing a post for them and them only after the session and see whether there are any differences.
A good teacher is not the one who proclaims themselves to be one.
Good luck!
Let’s just call it a blog post. I used the word “teaching” loosely and didn’t mean to hit a nerve. If somebody else called a carefully assembled sequence of learning units teaching, I wouldn’t blink an eye at that, so I applied this to the post. “Rigorously writing about sharing what I’ve learned in a way that I would’ve found useful” sounds good to me.
