The solution is Distance Education. Correspondence courses have been an option for many years. Students receive course information via mail, complete assignments at their own pace, and then mail the assignments back to their instructor.
Correspondence courses offer flexibility to students in scheduling coursework.
However, a student may feel as if he or she is taking the class in isolation. Many correspondence courses do not provide for interaction between the student and the instructor, other than times when assignments are graded and returned to the student. Students also do not have the opportunity to be in the community with other students, which can greatly enhance the learning experience. Telecourses involve viewing videotaped lectures. Exams are either proctored or administered in a take-home format.
