One of my visitors has a great blog on how to use podcasts for foreign language instruction. It also has great posts on podcasting in general. I especially like the description of how he got into podcasting. It's good information for anyone looking to do the same thing.
I also liked his observations on how to use a cell phone for school work. In NYC, the public schools ban cell phones. Needlessness to say, the parents are up in arms about that decision. Cell phones have become the only way for parents to know where their kids are between school's end and the time they get home.
