Watching an expert at work

A craft demonstration can make a complicated task appear effortless. An experienced potter, for example, may adjust hand pressure before a visible problem develops. A beginner watching the finished movement may miss the slight change in the clay that prompted it.

[A] Teaching can make such normally hidden decisions more visible. [B] The expert may pause to describe what the material feels like or deliberately compare two amounts of pressure. [C] The learner then has a particular signal to watch for when attempting the task. [D]

This changes the role of feedback. Instead of simply identifying an uneven result, a teacher can connect that result to a moment when the learner could have responded differently. The explanation becomes a guide for the next attempt.

Written instructions still have value. They can preserve the sequence of actions and remind learners of important checks. However, they may not fully convey the changing sensations involved in carrying out those actions. Combining instructions, demonstrations, and practice allows each form of guidance to support the others. Skill develops as learners become better at noticing relevant differences and choosing an appropriate response.
