Distance education
Distance education, also known as distance learning, is the education of students who may not always be physically present at school, or where the learner and the teacher are separated in both time and distance; today, it usually involves online education (also known as online learning, remote learning or remote education) through an online school. A distance learning program can either be completely online, or a combination of both online and traditional in-person (also known as, offline) classroom instruction (called hybrid or blended).
