From what I have seen, podcasts and videos seem to be a great way to engage students' interest in subject matter that they would normally find boring. I know that I am a visual learner, and I remember things best when I watch them, such as in a video. I'm sure that some of my students will be the same way since they all have different learning abilities and attributes.
This project has allowed me to realize how many different multimedia tools are available out there to help me teach math in a classroom someday. After all, I have always found that one is far more likely to remember and work hard at a topic which he or she enjoys. Videos and podcasts definitely help in that area.
In a classroom, I would probably use a podcast or video to introduce a topic or just for a fun change of pace. I would use it to spark conversation and pose questions about the topics presented and get students excited about the subject concerned.
