Distance education refers to instruction that occurs when the instructor and student are separated by physical distance and technology is used to connect them. It has several key characteristics, including the use of group activities and visual materials to encourage interaction. However, there are also some common misconceptions about distance education, such as that it is easier or takes less time than traditional education. When implementing distance education, instructors need to provide frequent feedback, be skilled with educational technology, and rethink their teaching practices. Students may face challenges like a lack of interaction, motivation, and student-teacher bonding. Trends in distance education include growing enrollment, personalized learning approaches, gamification, and increased mobile learning.
