From BJJ Mental Models:"The constraints-led approach (CLA) is a framework for teaching, coaching and practicing motor skills. It takes a holistic and individual approach to learning by considering the interactions between different ‘constraints’: the performer, the environment and the task. The CLA advocates a hands-off -approach, where the coach designs the environment and directs learning by manipulating the constraints, rather than using prescriptive instructions and corrective feedback. The learner is challenged to find his own functional movement solutions through variable practice and trial and error. The CLA is not a magic bullet for all learning situations, but according to preliminary evidence, it is an exceptionally well suited method for efficient motor skill practice."— Adaptive Movement

The old-school way:Just tell your students what you want them to do.

The constraints-led approach:Create games with constraints that force your students to do things the right way.

Have you run into anything in particular?

I've found some gyms justify certain requirements as "that's just tradition" with no reasoning, which irks me.

I think these are extremely useful. Learning how to learn is a valuable skill. Thanks Shawn!
