Have a visual learner who needs help with SAT vocab? With Got Brainy, students can create flash cards a la all those "inspirational" posters by uploading an appropriate image, then adding the vocab word and typing a sentence to go with it. Or they can just browse the plethora of cards already created.
There are also video options and a word list with definitions.
Creating these would also provide a good teachable moment for discussing ethical use of media.
Cathy Nelson, whose brilliance at teaching students technology I can only aspire to, shared this example of her students' video use of Got Brainy.
