How Big Data Is Taking Teachers Out of the Lecturing Business

Schools and universities are embracing technology that tailors content to students' abilities and takes teachers out of the lecturing business. But is it an improvement?

Sufficiently advanced testing is indistinguishable from instruction. In a fully adaptive classroom, students will be continually assessed, with every keystroke and mouse click feeding a learner profile. High-stakes exams could eventually disappear, replaced by the calculus of perpetual monitoring.

Teachers could come around, too. Arizona State's executive vice provost Phil Regier believes they will, at least: “I think a good majority of the instructors would say this was a good move. And by the way, in three years 80 percent of them aren't going to know anything else.”
