Free Technology for Teachers just posted this story about a new service called UTellStory. Sign up for a fee account, upload pictures, add captions or text, and narrate. It's like a slide show with your narration. The program gives you about 30 seconds of narration per slide and two minutes for total audio. It's a little like screen cast-o- matic. Students could create a news cast on a topic, narrate photos taken on a museum visit for extra credit, etc. Here's a sample story created by UTellStory.
