It is a word we hear from time to time, but few of us know what it means.

Utilitarianism is the method most people use to decide whether an action is right or wrong. We decide the moral merits of what we do on whether the consequences of that action are good or bad. But utilitarianism has recently been in the firing line of the press and radio and by some moral philosophers.

The belief that technology can automate education and replace teachers is pervasive. Framed in calls for greater efficiency, this belief is present in today’s educational innovations, reform endeavors, and technology products. We can do better than adopting this insipid perspective and aspire instead for a better future where innovations imagine creative new ways to organize education.
