Distance education or long-distance learning is the education of students who may not always be physically present at a school.
Traditionally, this usually involved correspondence courses wherein the student corresponded with the school via post. Today it involves online education.
An online school teaches students entirely or primarily online or through the internet.
It has been defined as "education that uses one or more technologies to deliver instruction to students who are separated from the instructor and to support regular and substantive interaction between the students and the instructor synchronously or asynchronously. Online education exists all around the world and is used for all levels of education .
This type of learning enables the individuals to earn transferable credits, take recognized examinations, or advance to the next level of education over the internet.
Virtual education is becoming increasing used worldwide.
There are currently more than 4,700 colleges and universities that provide online courses to their students.
In 2015, more than 6 million students were taking at least one course online, this number grew by 3.9% from the previous year. 29.7% of all higher education students are taking at least one distance course. The total number of students studying on a campus exclusively dropped by 931,317 people between the years 2012 and 2015
Experts say that because the number of students studying at the college level is growing, there will also be an increase in the number of students enrolled in distance learning.
