I looked at two different podcasting tools and will give each of them a try. The first one that showed up when I googled podcasting was Audacity. This tools seems kind of complicated but was easy to download. As well, I found this video on how to use it.
The second tool I had recommended to me was Audioboo.
Here is a video demonstrating how to use Audioboo.
I will give both a try and then use the easiest to record student opinion about how teachers can break down barriers in the classroom. I can't wait to share.
