I know what they are and what they are used for, I personally have never needed to use one or listen to one.
A podcast is an audio feed, one records and then uploads to a main source (e.g. iTunes), in which users can then come download the podcast onto their iPod or mp3 player which is saved there to listen whenever they please.
From reading the information given within my course content and the websites linked I have gained a new appreciation for 'podcasts'. Little did I know how many skills are being developed and defined when creating and using a podcast, found from 'The Magic of Learning' (2010):

Collaborative Skills
Writing Skills
Speaking Skills
Presentation Skills
Communication Skills
Media Skills
Oral Fluency
Technology Skills
Auditory Skills
Storytelling Skills
Information Literacy
Although the skills gained from podcasting are fantastic, I do not see how it could be a relevant tool for early childhood classes. I can see the relevance for mature students, such as; year 10 to university. However, I'm failing to see a way of incorporate podcasting into earlier years.
Please share your ideas and responses.
