The contemporary classroom, with its grades and deference to the clock, is an inheritance from the late 19th century. During that period of titanic change, machines suddenly needed to run on time. Individual workers needed to willingly perform discrete operations as opposed to whole jobs. The industrial-era classroom, as a training ground for future factory workers, was retooled to teach tasks, obedience, hierarchy and schedules.
That curriculum represented a dramatic departure from earlier approaches to education. In “Now You See It,” Ms. Davidson cites the elite Socratic system of questions and answers, the agrarian method of problem-solving and the apprenticeship program of imitating a master. It’s possible that any of these educational approaches would be more appropriate to the digital era than the one we have now.
