    The spread of Internet learning for huge numbers of people is leading some colleges to offer MOOCs, Massive Open Online Courses. Major universities like Stanford in California and Harvard in Massachusetts have invested millions of dollars to help launch MOOCs.

Those schools and others may have heard an attention-getting prediction. The man who created the MOOC service Udacity says that in fifty years, only ten traditional universities will remain in the world. That prediction came from Sebastian Thrun, a computer scientist probably best known for his part in making Google's driverless car. He is still a research professor at Stanford University. But he left his teaching position at Stanford to help start Udacity ,a provider of MOOCs.

Universities that fail to join the movement for MOOCs may be worried about their chances of survival. Colleges also hope to gain more students and cut operational costs in return for their investments.

Moody's Investor Service predicts that MOOCs will help large, famous universities gain more students. It says schools that create content for MOOCs can earn money by providing the course material to smaller schools.

But the investment service is warning that smaller, less well-known colleges may suffer because of MOOCs. It says students may want to receive certificates from major universities instead of attending a local junior college that provides traditional credits.

Recently, the University of Washington said it was the first American university to offer credit for MOOCs, credit that could be used toward a degree from the school.

One criticism of MOOCs has been that most courses being offered are in science, mathematics and technology. But several courses in literature are now available.

Professor Nelson says, "How much MOOCs will change college life is still up in the air. I have been of the opinion which is what universities will evolve to do is to still present some traditional classes, but that universities in some sense will be integrated."
