Using the Internet for teaching

I guess I thought I had been staying up to date on the use of technology in the classroom...I was wrong. I have seen more in a few weeks than I expected for the entire class. I am very interested in podcasts or anything I can use to allow my students to enable themselves to become part of the many tools that are available. We may not all have the labs we need but by allowing students to use technology, I feel I can reach some of those who may not feel challenged or excited about what we may be doing in class.
