When instruction is delivered at a distance, additional challenges result because students are often separated from others sharing their backgrounds and interests, have few if any opportunities to interact with teachers outside of class, and must rely on technical linkages to bridge the gap separating class participants. The success of any distance education effort rests squarely on the shoulders of the faculty. In a traditional classroom setting, the instructor's responsibility includes assembling course content and developing an understanding of student needs. Special challenges confront those teaching at a distance. Communication in human relations is the process of passing information and understanding from one person to another.
Communication always involves two people, a sender and a receiver.
One person alone cannot communicate. Only a receiver can close the communication circuit. Effective communication involves both information and understanding. Communication is not an end itself, but is the process by which ends are accomplished. It is the process by which leadership takes effect.
