Distance learning is widely defined as the learning and learning process when the learner and source of information are separated by distance, time, or both. If any such learning takes place for some reason (including exams), learning is considered "mixed" or "hybrid" learning.
The Internet has made continuing education through distance learning faster and easier for distributors and students. Over the last few years, the education sector has shown a remarkable increase in emphasis and impact on the "virtual university".
About a fifth university student in North America enrolls at least one online study, continuing to attend the education class, and requires 1 to 20 online education programs. The courses range from the simplest education to masters and doctors programs.
Accreditation levels vary widely. Some online educational institutions are nothing more than fraudulent "certified mills" that are not being monitored. But in the United States, the institution can not use the term "university" without government accreditation.
The technologies used in distance learning are divided into two categories:
1) synchronous learning technologies
2) asynchronous learning technologies
Synchronized learning technology resembles traditional classroom teaching at the same time and has a specific schedule. Technologies used for synchronized learning include Internet technologies such as VoIP, live streaming and video conferencing as well as television and radio (traditional and satellite) television technologies.
Asynchronous learning technology allows students to access the "evergreen" course and exams on their own schedule using the Internet. This, of course, allows greater flexibility, but it also allows for delay.
Synchronous and asynchronous distance education is often combined. The Internet blurs the difference between the two distance learning methods .
The development of distance learning technologies includes computer games, 3D (3D) private environments and virtual worlds
that can be transmitted and / or downloaded in real time and can also be accessed through a local hard disk.
Through online distance education / online distance education, all online training programs allow busy travel professionals to train on the road. When they fail, the entire program is easily accessible on the Internet to help them return to the track. Online education students will have access to the lessons within the classes, including university students, even if they are on the other side of the world! Is it your goal to meet the needs of space and time-bound students, ready to access digital books?
