Using Podcasts

I have used various Science Podcasts to begin each class period of my classes this year. This has lead to some unexpected results. I've had students comment regarding the science occupation discussed in the Podcast as well as discussions about the topic being discussed. In each and every class, students quickly help one another become quiet so they can hear the Podcast. It has been a great way to begin classes. While the topics are not necessarily the same as that day's lesson, each covers some science topic. Perhaps what I like best is that it encourages students to look for ways to learn about science on a continual basis. Several students have asked what the source is for the Podcast. They then indicate they want to listen to more:) I'm not sure I would ever complain about students learning science on a voluntary basis! They have been told that I expect them to create at least one Podcast about a class lab during each term. More to come...
