Copying

A lot of tai chi classes operate on a 'follow-the-leader' basis, where the students simply watch and copy the teacher.

The students are never asked to train the form by themselves.

This is contrary to learning. Copying is not understanding.

If a student cannot practice the form without the teacher, then the teacher is a failure because they have not taught anything.

The role of the teacher is to pass-on their knowledge and skills.
