MOOCs are massive open online courses that deliver educational content online to anyone interested in taking the course. They work by having a professor and technical team develop course content, which is delivered through the internet to students. Students have flexibility to learn at their own pace and are assessed continuously in an interactive online environment. MOOCs provide benefits to students, professionals, professors, universities, governments, and content providers by increasing access to education and skills development while reducing costs. However, challenges remain around student engagement, assessment, and replacing traditional education.
