Check out the movie I have made on how I use Podcasting in my classroom.
This is an example of a student podcast, that was made last year by one of my students.
This podcast is based on a Poetry unit and the children learned the structure of Haiku Poems. There's nothing like seeing / hearing something in action made by the children.
When implementing podcasting in a whole class setting, there needs to be a lot of training done around managing noise level of children, especially those who are not recording.
I think that's one of the pitfalls. This can easily be addressed. I use a traffic light system to highlight the appropriate noise level for when I am recording children. This is a visual aid which sets expectations for noise level in the classroom.
If you have a very young class it maybe the teacher that is editing the podcast at the end before it is uploaded onto a Blog or Wiki. Making podcasts can be quite a time consuming process, however it can be extremely rewarding in a number of ways. Children can get to listen to themselves speak and can critique their own performance. Podcasting can help build confidence for children around speaking clearly, loudly and with expression. From my own experience, Podcasting provides motivation and engagement for students. It can be integrated into all of the curriculum areas and links to the Ministry of Education's Key Competencies: "Managing Self", "Relating to Others", "Using language, Symbols and Text", "Participating and Contributing", and "Thinking".
