Liz Kolb converted from being one of those teachers who didn't see value of cell phones on campus" to devising ways to use cell phones as learning tools. Kolb, a former middle school and high social studies teacher and technology coordinator, said she was doing a blogging activity with a group of teachers when a message popped up on her screen telling her she could create an audio-blog with her cell phone. "It was the easiest podcast I ever made. I said, Wouldn't this be a great way to do podcasts as homework!' It was a real ah-ha moment," she says.
