I found this interesting:
Education professionals should be familiar with the no significant difference phenomenon (NSD). This phrase refers to a body of research that indicates “the mode of delivery of education has no effect on student outcomes” (Western Cooperative Educational Telecommunications [WCET], 2010, FAQ section).
Excelsior College surveyed more than 1,500 CEOs and business owners and found that “83% of them strongly believe a degree from an online college is as credible and valid as one from a traditional campus-based school”
