Which university was the pioneer in the concept of microteaching, started in 1961?

Stanford University pioneered the concept of microteaching in 1961, giving teacher training its scaled down skill practice model.

The Stanford model built the now standard teach, feedback, reteach and refeedback cycle.

Oxford University is not associated with the origin of microteaching and is a distractor here.

Delhi University adopted microteaching later in India but did not originate the concept.

JNU, New Delhi is unrelated to the invention of microteaching and is simply a wrong option.

Dwight Allen and Robert Bush led the Stanford project, later formalised with Kenneth Ryan.
