MOOCs, or Massive Open Online Courses, are online classes designed to accommodate a large number of participants. They are typically offered by universities and educational institutions, allowing anyone with internet access to enroll and learn at their own pace. MOOCs cover a wide range of subjects, from computer science to humanities, and often include video lectures, quizzes, and discussion forums. These courses are usually free or low-cost, making education more accessible to people around the world. While some MOOCs offer certificates upon completion, they do not typically provide college credit. This format has transformed traditional learning by promoting flexibility and inclusivity in education.
