Role of Information Technology in distance education

Information technology plays a vital role in distance education. In fact, it is safe to say that modern distance education would be impossible without access to technology that can deliver information via the Internet to students in multiple locations.

The Internet

An Internet connection is essential in most distance learning programs. This is the means by which information is disseminated to students. In almost all distance learning programs, students are required to have access to the Internet and an email address.

Computers

A personal desktop computer or laptop computer is an essential tool for distance learning. This is where work is produced and data is accessed. Wireless laptop computers allow students to participate in class activities from anywhere Internet access is available.

Interactive Audio and Video

Interactive audio and video allow real time communication using phones and computer. Voice over Internet Protocol (VoIP) enables a person's voice to be transmitted through an Internet connection. Voice and multimedia presentations can also be delivered to a dispersed class with questions and answers taking place in real-time.

Fax

Fax can be used when paperwork needs to be distributed or when signed copies of documents need to be delivered.

Software

Many software applications designed to facilitate distance learning are available to instructors. These programs integrate material and organize it so it can be accessed from computers. Students can record lessons and access pictures, slides and notes at their convenience. Security protocols allow only registered students to access material, and assessment programs provide secure testing environments with automated grading and instant feedback.
