Distance learning is not a modern phenomenon. It actually dates back as far as 1728 when Caleb Phillips, a teacher in Boston, Massachusetts, offered shortland lessons to students via weekly mailed lessons. In the early 1840s, long before the advent of the Internet, Isaac Pitman, a British educator, also taught shorthand through correspondence courses. Distance learning and education have a long history, but its popularity increased a hundred fold as more advanced technology and communication mediums became available in the late twentieth century.
Distance education first took hold in the 1930s, with over 25 state boards of education, 200 schools systems and several colleges and universities offering educational programs broadcast over public radio. However it wasn't until the advent of the Internet in the early 2000s that the availability and popularity of distance learning programs skyrocketed. Computers and the internet made distance learning faster, easier and much more convenient. By 2008, web-based, online education programs were available in most states in the US at the k12 level.
Today, enrollment in distance education programs at every educational level is common place. Private, public, non-profit, and for-profit secondary, post-secondary and higher education institutions, including high schools, colleges and universities, now offers distance education programs in just about every field of study imaginable. From basic literacy to doctoral programs, distance education courses at available at every level of instruction.
The InternetWhile distance education programs are offered via a large variety of communication mediums, online distance learning, via the Internet, is now the norm. In 1996, Jones International University was the first higher education institution to launch a fully online accredited degree program. In the following years, most major colleges and universities quickly followed suit. Reputable higher education institutions such as Harvard University and Stanford now offers distance learning programs for their students entirely online. By 2011, about a third of all college students had at some point taken an online course.
Even though for-profit universities have been the quickest to adopt and exploit Internet technology to offer online degrees to the masses, the majority of public colleges now offer their academic programs completely online as well. Common fields of study pursued online include, but are not limited to, programs in business, psychology, criminal justice, health sciences, computer science, design and liberal arts.
Distance learning has quickly been adopted as the training and education method of choice among busy working professionals. Online distance learning programs offer the most affordable and convenient means of earning a degree, improving skills and pursuing a higher education.
TechnologiesThere are two modes of delivery for distance education technologies: synchronous learning and asynchronous learning.
In synchronous learning, all learners participate in the education experience at the same time. A traditional classroom is an example a synchronous learning experience, where students participate jointing in learning and class lectures. With respect to distance education, synchronous learning methods includes videoconferencing, web conferencing, educational television, internet radio, direct-broadcast satellite (DBS), live streaming video, web-based VoIP, and even telephone. Many modern software programs, such as Adobe Connect, facilitate synchronous distance learning.
Asynchronous distance learning is much more flexible than synchronous learning. Students are able to access course materials whenever they want, from wherever they want – and are not required to be with other students during the learning process. The oldest form of asynchronous distance learning technology is mail correspondence, which has been employed for over a century. Today e-mail, video and audio recordings, message boards, print materials, fax and stream video over the Internet facilitate asynchronous distance learning. Asynchronous distance education is the mode of choice for most online colleges and universities seeking to provide their students the most flexible and convenient distance learning experience possible. However, many higher education institutions blend asynchronous learning with synchronous learning.
