Online learning involves education that takes place over the Internet, as one type of distance learning. It allows instructors to design flexible courses using different tools to enable learning. Strategies for online learning include regularly communicating with professors, actively participating in online discussions, and setting your own pace of work. Pros are flexibility, the ability to work at your own fast pace, and more comfortable learning styles being supported. Cons include some content not being available online, needing self-discipline as no one makes you attend or complete assignments, and risks of technology problems. It requires self-motivation for self-study without in-person control or attention.
