Distance learning, starting from correspondence courses in the 1840s, has evolved significantly, especially with the establishment of institutions like the UK's Open University in 1969, which utilized a mixed-media approach. Despite the growing interest in this mode of education, research on its effectiveness is limited and often flawed, raising questions about retention rates and student outcomes compared to traditional classroom settings. Moreover, the increasing use of technology has made distance education more accessible, allowing non-traditional students to balance their studies with personal obligations.
