I just opened my email and discovered this brilliant post by Audrey Watters, whose critical voice on EdTech is indispensable.

Watters lists the 100 biggest EdTech debacles of the past decade, and seeing them all in one place is astonishing.

What strikes me is the combination of unadulterated arrogance (i.e., chutzpah), coupled with repeated failures.

What is also impressive are the number of entries that were hailed by the media or by assorted journalists, then slipped quietly down the drain, without impairing the reputation of the huckster who took the money and ran.

Again and again, we encounter EdTech start-ups and innovations that are greeted with wild acclaim and hype, but whose collapse is ignored as the parade moves on to the next overpromised miracle technology.

Whatever happened to the promise that half of all courses in school would be taught online by this year (false) or that most colleges and universities would die because of the rise of the MOOC (false)? Why do virtual charter schools make money even though they have horrible outcomes for students (lies, lies, lies)?

This post is stuffed with flash-in-the-pan technological disruptions that planned to “revolutionize” education, from K-12 through higher education but then tanked.

Please read it. Share it with your friends and colleagues.

Lessons: Learn humility. Believe in the power of human beings, not machines designed to replace them. Don’t let them sell you stuff designed to control the brains, emotions, and social development of students. Be wary. Be skeptical. Protect your privacy and the privacy of children.

Protect your intellectual freedom.
