Free! HACKTIVITY KITS is a collection of nine hands-on and web 2.0 activities intended to explain and reinforce the concept of web hacking -- that is, the idea of remixing, reusing, and re-purposing existing content to create new material or glean interesting insights. Created by NYC HIVE, a MacArthur Foundation-supported group of civic-minded organizations (there's a Chicago one, too), the Hacktivity Kits are largely built upon Mozilla WebMaker tools: Popcorn Maker, Thimble, and X-Ray Goggles. Each Hacktivity includes a detailed list of learning goals and objectives, expected results, and supporting resources. There's also an extensive list of icebreakers to get the creative juices flowing and skills tutorials for the WebMaker tools. For example, look to the Online Storytelling kit which explains the SVT (Story, Vision, Tech) model for making "web native" stories. In addition to introductory tutorials on how to use the kit and associated technology, there's also the Spectrogram icebreaker, Popcorn Maker deep-dive, and an out-of-the-box design challenge for teachers just getting their feet wet.
