This presentation by Melinda Kolk is showcasing software by Tech4Learning. This isn't the first time I've met up with someone from that company.
They have more than one product, the first they're showing is a program called Frames that can be used to make animations out of still images. iMovie has the same functionality, but its interface isn't designed specifically for that. Frames' interface is.
She's admitted that iMovie and Photostory have similar functionality. It's not about the technology, it's about how these kids are learning.
Each of these videos she's showing is helping to reinforce "core" (I still dislike that label) content areas. Some of them involve cross-grade collaboration, which is neat.
