School of the Air is the term used for correspondence schools catering to the primary and early secondary education of children in remote and outback Australia. Some or all of the classes were traditionally conducted by radio.
The "school" leveraged the radio network established by Reverend John Flynn as part of the Royal Flying Doctor Service. This network was powered by another great Australian innovation – Alfred Traeger's pedal-powered radio .
The first lesson was broadcast in 1948 from the Alice Springs RFDS base. A few years later, the School of the Air (SOA) was officially established
It's important to note that the technology adopted and developed was two way radio, so rather than passively listen to a teacher, students were able to interact with peers and the teacher.
