Brilliant references worth incorporating indeed. Radio Enseña's thirty minute packages provide the flexibility to incorporate content into existing channels while podcasts provide a offline learning model. I am particularly impressed by the distribution model of the podcasts which includes some of the accessible models such as WhatsApp, SoundCloud and MixCloud. All of these channels are familiar and popular to the target age group.
Most developing countries still have public broadcasters (both radio and television) which makes the idea for donated broadcasting air time relatively easier to implement. So that's a great idea, thank you for that.
Evolving the idea so that it continues to be provided even once we are out of this is something that will need to be tested. If the quality is higher than in the schools, I see no reason why the students will not find this attractive.
