Many educational programs are beginning to provide people with the opportunity to receive a valuable education without having to receive a multitude of student loans.
What is it?
At its most basic level, distance education takes place when some sort of physical distance separates a teacher and student. Technology (voice, data, print, or video) is often used to bridge the instructional gap. These types of programs are ideal because they can offer adults a second chance at a college degree, they can reach out to people who are limited by time, money, distance, or physical disability. Distance education can also be used to update the knowledge of current employees.
Is this form of education effective?
A major objection to distance education is that it does not offer the same value that face-to-face interaction provides between the teacher and student. Many would argue that this form of education is far too impersonal to be truly worthwhile. Research comparing this type of education to traditional face-to-face instruction tells us that teaching at a distance can be just as effective when the technologies used are appropriate to the instructional tasks.
How does it work?
There is a wide range of technological options that you can use in order to enhance your educational experience. The educator can choose between options that fall into four major categories:
- Voice – Audio tools include interactive technologies of telephone, audio conferencing, and short-wave radio. One-way audio tools include tapes and radio.
- Video – Instructional video tools are still images such as slides, film, videotape, and real-time moving images combined with audio conferencing.
- Data – Computers send and receive information electronically which is why “data” is used to describe this broad category. This option includes four variations: Computer-assisted instruction (CAI), Computer-manages instruction (CMI), Computer-mediated education (CME), and Print.
Which technology is best?
Typically, the most effective systematic approach results in a mix of media, because each serves a specific and different purpose. The result is well-rounded educational experience for the students. A strong print element, for example, can offer excellent course text, readings, syllabi, and daily schedules. Interactive audio or video conferencing can incorporate guest speakers or content experts. Computer conferencing is good because it can be used to send messages, feedback, and increase interaction. Videotapes can present class lectures, while fax might be good for assignment distribution and last minute announcements.
What makes for successful distance education?
Although technology plays a vital role in the delivery of this sort of education, educators must remain focused on instructional outcomes and not the technology they use to deliver. They key to this effective education is focusing on the needs of the learners, the requirements of content, and addressing the roadblocks that arise prior to choosing a technological option. Without a doubt, effective programs begin with careful planning and a sharp understanding of course requirements and student needs. These elements must be fully grasped before appropriate technology can be selected. These types of learning environments evolve slowly over time through dedicated work and experiments of numerous individuals. The educators must adopt teaching styles that take into consideration the needs and expectations of multiple and diverse audiences.
