Podcast is the one of the greates invention among morder technologies. I have iphone so I have already used the podcast. The thing I found is NPR potcast directory
which is the news podcast categorized by the topics. In there there are lots of podcast news.
One that I heard was The environment Report Podcast which was telling about the environment report. The story was about like below. "We're revisiting a Michigan farmer who raises heritage turkeys. Those are turkeys that have a little bit of a wilder history than the usual supermarket bird. Some farmers are trying to keep these older turkey breeds from going extinct. But as we'll hear, it's not the easiest job in the world."
Some special turkey is going extinct so they gave thier opinion how and why we have to stop this for keeping our tradition.
In my future teaching, I will make the students hear some news and make them summarize the news or if they are enough to have high language skills(ex. college or adult adavanced class), they could make the comprehension questions for the other students.
Through this activity, the students can imporve their language skills and have background knowledge for various news. If I can find more sources in podcasts, this would be wonderful tool for teaching English.
