New content and notable corrections, newest first.
Motion graphics
- Animated teaching diagrams: the 3D printing workflow, the water cycle, graph scale, the SAMR ladder, and SIFT.
- A hands-on slicer visualizer that shows how layer height and infill change a print.
- Every animation has a pause button and stops when it's off screen. If your device is set to reduce motion, you see the finished diagram instead.
- Added a page for Teacher Planner, a desktop lesson-planning app made by the creator of this site, with download links and install help.
- Updated the editorial policy to disclose that connection, and the privacy policy to explain how the download page contacts GitHub.
- Added a privacy policy, accessibility statement, editorial policy, and contact page.
- Every page now shows when it was last updated, with a link to report a problem.
- Pages built on published frameworks (UDL, SAMR, SIFT, CCSS, NGSS, ISTE) now list their sources.
- Content is now licensed CC BY-NC-SA 4.0 so teachers can reuse and adapt it.
