Podcasting is becoming increasingly popular in education. Podcasts enable students and teachers to share information with anyone at any time. An absent student can download the podcast of the recorded lesson. It can be a tool for teachers or administrators to communicate curriculum, assignments and other information with parents and the community. Teachers can record book discussions, vocabulary or foreign language lessons, international pen pal letters, music performance, interviews, and debates. Podcasting can be a publishing tool for student oral presentations. Video podcasts can be used in all these ways as well . Also embedding slides with audio see enhanced podcasts(wikipedia).
