He encontrado en Internet que ya existe la Podagogy o pedagogia utilizando el podcasting.
Los invito a seguir el link y averiguar más.
Podagogy is the art or science of using Podcasts for educational purposes. These are some sources of information on Podagogy.
Although it is important to point out these are informal sources, none of which have developed models of Podagogy which will be the outcome of this project.
This is a blog page that disscusses the concept of podagogy. It also has many other useful references to Podcasts on the subject.
