【正确答案】Distance learning is a formal educational process that breaks the traditional mode of classroom teaching. There are two key differences between traditional education and distance learning. Distance learning adds flexibility and availability, regardless of time, place, or pace of learning. Here an instructor teaches, and somewhere else a student learns, regardless of barriers of time or place. Distance learning reaches out to non-traditional students who must fit their studies around workplace, family responsibilities, and geographical barriers, etc. Students can be at satellite campus , at the workplace, or at home. Instruction may take place in real time or on a time-delay basis. Interactivity between student and instructor, as well as students themselves can be built into a program. The outcome can be a bachelor' s degree or a master' s degree, professional certification, on-the-job training, or life-long learning.
