How did MOOCs change distance learning in the early 21st century?

The emergence of Massive Open Online Courses (MOOCs) in the early 21st century marked a significant shift in distance learning by scaling education to tens of thousands of students globally. Unlike earlier correspondence models, MOOCs utilized Internet platforms—such as Coursera, edX, and Udacity—to deliver short, videotaped lectures and automated assessments.12

MOOCs transformed higher education in several key ways:

• Access and Scale: They were positioned as a solution to the rising global demand for higher education, offering a way to reach massive audiences that physical universities could not accommodate.2
• Pedagogical Shifts: The model introduced peer-to-peer grading and gamified learning experiences to manage the challenges of high-volume enrollment.2
• Institutional Integration: While initially informal, MOOCs evolved to include experiments with degree credit and professional certifications, often through partnerships between universities and commercial providers.12
• Economic and Academic Debate: Administrators viewed MOOCs as a way to reduce costs and reach global markets, while critics raised concerns regarding the devaluation of knowledge, the loss of human interaction, and the potential for a two-class university system.2
