If you haven’t already experienced a MOOC — that’s Massive Online Open Course — now is a good time to check them out.
The courses are offered on line at no cost to tens of thousands of people. They’re organized and taught by faculty from first-rate universities, including University of Toronto.
There are two major sites. Coursera.org is an international consortium including Canadian universities. Edx.org is an initiative of Harvard and M.I.T., with faculty from several first rate American schools.
You can audit a course with no obligation to complete assignments or interact in any way. Or, you can register with a commitment to participate and complete assignments and be rewarded with a certificate of achievement.
And it’s all free."
