How I Use It
This is a good tool to assess student's prior knowledge about a topic. It's also good to use for open discussion. Students can post ideas. Students who have difficulty taking notes can export the board to their email. At first it may not seem intuitive, but once they get the hang of it, it works like a charm. Make a tinyurl of the page and share with your students.
I would recommend this site given its ease of use, little setup time and high interactivity. Given how long my special education students use taking notes, I will use it with them to avoid them missing important details.
