Middle school lesson for introducing Inkscape, the open source vector graphic program. Very cool project-based learning idea--students will create a logo, album artwork, poster, and tour T-shirt for a fictional band. This post is the first lesson; more updates are planned as the course progresses.
Quick summaries of key points from each chapter in a book on learning science and effective strategies (spacing, elaboration, concrete examples, visuals, and retrieval practice). I wish the graphics were easier to read though. Medium blue italicized serif text on a lighter blue background isn't enough contrast. I don't think low contrast counts as desirable difficulty, just bad accessibility.
