Hi people, I just wanted to say thank you to the LessWrong community for exposing me to the concept of "bayesian probability". Apparently human motor programs function in a bayesian way, with each movement prior predicted including predicted sensory feedback of said movement, which enables a comparison of prediction with perceived reality. Pretty cool.

Learned of the observational evidence supporting random practice over blocked practiced as they relate to motor learning and retention, 14/5/2015.

Wrote a new lesson plan for my squash juniors, based upon the aforementioned idea of random practice, which I offer freely to LW.

Implemented an approximation of the above program in today's session, after explaining why the changes are occurring. I observed that the young athletes were more enthused.
