Plan your video. Making a math video podcast for your students requires planning. At the very least you should have an outline. Writing detailed notes, or a word-for-word script, might be better. This will help prevent you from making mistakes. Treat the video podcast as you would a lecture in your class. Prepare for it with the same seriousness.
Set up your webcam or camcorder. If using a webcam, connect it to your computer using a USB cable. Make sure that you frame yourself well. Take care that you are well lit.
Set up your microphone. Plug your microphone into your computer. Attach the USB cable or microphone jack to your computer. Place the microphone in a place that records your voice at a good level.
Record your content. Begin recording your math video podcast. Make sure that your speech is clearly enunciated and delivered at an easy to follow pace.
Compress your video. Before your math video podcast can be uploaded to the Internet, it must be compressed. The raw footage is simply too large. This can be easily done with a number of programs, including iMovie or Quicktime Pro. There are also free programs that compress video if you or your school's computer doesn't have iMovie or Quicktime Pro. Compressing video is easy, requiring no special skills. It is simply a matter of finding the specific drop-down command and allowing the program to do its work.
Upload your video. Upload your video to a video hosting site such as Vimeo or YouTube. These sites are great for hosting video, as they are free and open to all. Your students also probably already have accounts, so they can subscribe to your channel.
Blog your video. Set up a free blog for you math video podcast. This will allow students without a YouTube or Vimeo account to subscribe to your podcasts using an RSS feed. To put a video podcast into a blog, copy the embed code from your video hosting site and paste it into a blog entry.
