Geddit

Geddit is a new educational tool that I just found out about from Edshelf.  This is a wonderful site that allows students to use any mobile device to gauge their understanding of any given topic/lesson.  The way this works as a lesson is being given they click/tap a on bar (think bar graph increasing vertically) to show their understanding (i.e., 1 bar - not very - 4 bars - very).  On the the teacher's device they will receive instant real-time feedback and be able to see which students are doing good and which ones are struggling.  This is a great way for teachers to differentiate instruction and adjust their lessons to meet individual needs.

I highly recommend checking out Geddit by clicking here!!!
