I used to spend about an hour a day grading and analyzing 30 exit tickets. After finding out about socrative, that time has been cut down to about 5 minutes a day. I simply write my exit slip as a quiz on socrative, which allows for multiple choice and short answer questions, and have the kids answer the questions on their ipads when the lesson is over. Socrative automatically gathers the data and allows for it to be exported as an excel spreadsheet. What makes this app even more amazing is I can see the results laid out for me as soon as my kids are done with the exit slip, so i can remediate right then and there if I need to. I would suggest this to any teacher that can use an extra 55 minutes in their day!
