“Teachers for years had been accustomed to flying blind – that is, not having objective criteria with which to measure the effectiveness of their lessons.” Now, “the criterion is mastery of the objective and what gets you there best and fastest.”
KEY IDEA: All other things being equal, the simplest explanation or strategy is the best. Champion teachers are generally inclined to make their lessons motivating by switching among a series of reliable activities with a variety of tones and paces. The terrain always changes, even on the shortest path between two points.
