Online learning is a form of education delivered via the internet, allowing students to access content, interact with instructors, and collaborate with peers remotely. It can be synchronous (real-time) or asynchronous (self-paced) and uses digital platforms like Zoom and Google Classroom. This approach offers flexibility and incorporates tools such as video lectures, quizzes, and discussion forums. However, it requires students to be self-motivated and skilled in time management and technology. While it enhances accessibility, challenges include reduced social interaction and technical issues, making student engagement and course design key to success.
