I think teaching 101 covers widely discredited education theories (stuff like Myress-Briggs, visual auditory and kinesthetic learning styles, and the like) rather than practical teaching tips. There's a practicum to teach them how to teach.
I mean if you actually get a masters in education, it's almost all practical stuff. You need to take entire classes on things like how to write on a chalkboard and how to spot kids who are being abused at home. Educational theory and research is only one or two classes out of the two years. And classroom management is one of the biggest topics, and it's the first thing you get evaluated on when you're doing your student teaching.
Not the masters in education I have. I heard tales from very old timers about having to take "write on the chalkboard" classes, but that was never even brought up for us. Though frankly, that specifically should be. Maybe not a whole course, but a few days of it. There are a lot of ways to get that wrong.
But back to your point. My degree is from a university in Boston and helped me get my teaching license. Almost everything we covered was theoretical and, with a few important exceptions, utterly useless.
