Study Blue is a website for students to share and collaborate on the creation of study tools. High School and college students can share notes from class, create multi-media flashcards, email, and share calendars using Study Blue. Students can establish study groups or search for study groups already creating on Study Blue.
Wow. Great free site where you can create polls and online quizes. They can be embedded into your website and voting can be restricted to one vote per person. Lots of great possibilities.
My students told me about this site where they make study guides and flash cards for themselves. It's free, and it would be particularly good for studying information that you have to memorize.
