Educational technology has evolved over time from the use of silent films and radio in classrooms to today's use of computers and Internet connections. Key developments include the rise of audiovisual education aided by World War II, the introduction of educational television stations, and the widespread adoption of microcomputers in schools during the 1980s. While technology provides benefits like improved access to materials and student motivation, its implementation also faces challenges such as adequate funding, training for teachers, and ensuring media literacy.
