Distance education has evolved over time, starting in the late 1800s to expand access to education. It utilizes various technologies, like email, internet, television, and post, to deliver instruction to students who are not physically present in a classroom. Key components of effective distance education include strong management, high-quality course content and design, engaging delivery of materials, and support for students' learning needs. Distance education programs continue adapting to changing technologies and financial pressures, and may become an increasingly important model for expanding educational access in the future.
