Death Knell for the Lecture: Technology as a Passport to Personalized Education

[Commentary] Our education system is in a state of crisis. Among developed countries, the United States is 55th in quality rankings of elementary math and science education, 20th in high school completion rate and 27th in the fraction of college students receiving undergraduate degrees in science or engineering. As a society, we can and should invest more money in education. But that is only part of the solution. The high costs of high-quality education put it off limits to large parts of the population, both in the United States and abroad, and threaten the school’s place in society as a whole.

We need to significantly reduce costs while at the same time improving quality. The key to this transition was the use of technology—from crop rotation strategies to GPS-guided farm machinery — which greatly increased productivity. By contrast, our approach to education has remained largely unchanged since the Renaissance: From middle school through college, most teaching is done by an instructor lecturing to a room full of students, only some of them paying attention.
