Unfortunately, this guy, Shawn Wheeler, just stopped his podcast and changed jobs, but there are some great resources for designing and creating your own podcast. Yet, another resource for delivering content to students that I think teachers would do well to explore.
Another digital storytelling resource. This resource focus' on using the modality for content storytelling, so if you've been reluctant to explore digital storytelling in your classroom, then think again. It's a great set of ideas for developing rigorous stories for content of multiple grades and content areas.
Nice little set of quizzes that students can take quickly. Helps memorize some of the features and other facts students need to know for unit study. Interactive and fun. I took two of the quizzes and need to work on my great lakes. How well can you do?
