Applied Behavioral Analysis: Errorless Learning

Here are it's applications to Learning Math
And I absolutely believe this: "Seeing maths worked out in real time, with failures, and how a professional deals with failure, is essential for learning, and at the reasearch level. I remember thinking after an all day session with Michael Barratt in 1959: "Well, if Michael Barratt can try one damn fool thing after another, then so can I!", and I have followed this method ever since. (Mind you his tries were not all that "damn fool", but I am sure you get the idea.) The secret of success is the successful management of failure, and this is perhaps best learned from observation of how a professional deals with failure."

Which is why candid livestreams are so important in the absence of professional apprenticeships.
