ExitTicket was a rapid prototype system to test in four urban high schools around the San Francisco bay area. The purpose was to drive instruction by creating immediate feedback to students in real-time. Teachers could immediately check for understanding, intervene as needed and retest in a very short amount of time. It was designed to run over the web using jQuerymobile as the framework. 

 

The results of this system, benchmarked over two years with the baseline of not using a system of this type in class, yielded 2.6 years of knowledge learned in just one year.
