What is a Podcast?

In its simplest form, a podcast is an audio file (usually in mp3 format) posted to a website, so that others may listen to it. Many podcasts are automatically delivered over the Internet using either RSS or Atom syndication. Subscriptions to podcasts are usually free, and once subscribed to, it can be automatically downloaded over the Internet and accessed with an iPod, laptop, or desktop computer.[1]
Podcasting can be used to assist students’ vocabulary, writing, editing, public speaking, and presentation skills. Classroom teachers can create a podcast of daily assignments/lectures and publish it for their students. Likewise, students can create and publish content and deliver it to their teachers or to other students. Many educators have found that when students create content for a larger audience (beyond their classroom walls); they have more interest and motivation to work harder to improve the quality of their work.
