I have taught at a number of institutions that have accreditation as an online university, and one factor is ultimately more important than any other in online education. It is the individuals who teach the course that inevitably create an environment where engaged learning takes place.
One institution that has made significant strides in online education is Western Governors University, which is a private accredited university with a non-profit status. WGU's commitment to making college affordable has been remarkable, and the university offers offers bachelor's and master's degrees in a number of fields, including an online degree in information technology (IT).
Attaining a degree online requires as much (or more) effort as one puts forth in a traditional face-to-face classroom. One of the best characteristics of online education is that students are able to complete coursework around their busy schedules. WGU offers students an affordable online education option, and prospective students are encouraged to consider the many fine programs the university offers.
