Distance learning provides access to education beyond traditional classroom settings by separating teachers and students across time and distance using various technologies. It allows flexible learning as students can complete courses without being physically present on campus. Key aspects of distance learning include using print, audio, video and computer technologies to deliver course materials and facilitate interaction between remote students and instructors. While it increases access to education, distance learning also faces challenges like high dropout rates and limitations on real-time interactions compared to in-person instruction.
