The Teacher Function in the AI Age
Ericsson's precise analysis of what teachers actually do in deliberate practice — design challenges, not merely instruct — and why current AI systems cannot replicate the function despite their unparalleled capacity for instruction.
The teacher's role in deliberate practice is often misunderstood as primarily instructional — the teacher tells the student what to do, and the student does it. Ericsson's framework describes something more complex. The teacher's primary function is not to instruct but to design. The teacher designs practice activities that create the conditions under which the specific representational growth the student needs will occur. The vocal coach who hears a singer straining does not simply say 'relax your throat.' She designs an exercise — a descending scale on an open vowel, a passage that cannot be sung with tension — that makes relaxation a condition of success rather than an instruction to follow. The exercise does the teaching. The teacher's expertise lies not in knowing the right answer but in designing the right challenge. This distinction between instruction and design is the fulcrum on which the comparison between human teachers and AI systems turns.
