Podcasting involves creating recorded audio files that can be downloaded and listened to on mobile devices like iPods. It is an alternative to traditional radio or television that allows users to access content on their own schedule without commercials. Creating a podcast requires only a few basic tools - a computer, free audio software, a microphone, and a hosting site like Podbean to publish the files. Podcasting has grown tremendously in popularity since 2007 and represents a new technological innovation that can transform teaching methods by influencing teaching pedagogy away from traditional lecture-based approaches.
