Open courses are educational programs that are freely available to anyone interested in learning. They can be found online and cover a wide range of subjects, from mathematics to computer science and art history. These courses often include video lectures, reading materials, and assignments, allowing learners to study at their own pace. Many universities and organizations offer open courses as part of the MOOC (Massive Open Online Course) movement. This initiative aims to make education more accessible and inclusive, enabling people from diverse backgrounds to gain knowledge and skills without the barriers of traditional classroom settings.
