The paper examines trends in enrollment and completion rates of massive open online courses (MOOCs) since their inception, focusing on data that has become publicly available. It highlights that the average MOOC course enrolls around 43,000 students, with a completion rate of 6.5%. Enrollment numbers are decreasing over time and are positively correlated with course length, while completion rates remain consistent across time, university rank, and total enrollment but are negatively correlated with course length. The study provides a detailed view of these trends, offering insights into how the MOOC field is developing. Key findings include the decreasing enrollment numbers, the consistency of completion rates, and the negative correlation between course length and completion rates. The study also discusses the limitations of the data and suggests areas for further research, such as the impact of different pedagogical approaches and assessment types.The paper examines trends in enrollment and completion rates of massive open online courses (MOOCs) since their inception, focusing on data that has become publicly available.
