A MOOC is a massive open online course that is accessible to unlimited participants via the web. MOOCs provide traditional course materials like videos and readings and allow students and educators to interact. The main advantages of MOOCs are that they are free, short in duration to address single topics, and ensure students keep up through tests and assignments. However, meaningful discussion is challenging with large class sizes, students more easily drop out, and grading thousands of papers poses difficulties for professors. Assessments typically involve machine-graded multiple choice quizzes or peer-reviewed written assignments using rubrics or sample answers.
