Wikipedia translation of the week: 2022-17

The winner this Translation of the week is en:School of the Air Please be bold and help translate this article! School of the Air is a generic term for correspondence schools catering for the primary and early secondary education of children in remote and outback Australia where some or all classes were historically conducted by radio, although this is now replaced by telephone and internet technology. In these areas, the school-age population is too small for a conventional school to be viable.
