Those that offer only distance learning is referred to as "open universities," and most are
modeled after the United Kingdom's Open University. Mega-universities are large open
universities, each of which enrolls more than 100,000 students per year; combined
enrollment is some 2.8 million. (http://tojde.anadolu.edu.tr/fdmarchnws.htm) 2008-2009 education-teaching period, distance education became more common in
undergraduate education with the new programmes which universities started. At the
present day, universities continue their studies on distance education with two-year
degree education, undergraduate education and graduate education programmes. (Arar,
