Distance education is often described as "self-directed" learning. Distance education courses / programs mean that students do not attend classes on campus. The work is completed from their own home. Students may have a textbook, but a fair amount of the material is provided electronically and work is submitted through mail, email or an online system. You do not have face-to-face interactions with other students or your professors. This type of learning requires discipline and self-motivation.
The flexible schedule of distance education means you may be able to continue working while studying. Distance education programs and courses may be able to help you upgrade your skills or change careers while still working.
