Pupil Picker Free is a simple but very powerful tool that can be used by any teacher, kindergarten through college to increase student engagement. Pupil Picker Free uses your iPhone's Address Book to randomly select students while you ask your students questions or check answers.Pupil Picker will dramatically increase your students' engagement because they know that they may be called on at any time. Use the Student Repeat setting to control how quickly a student can be called on again. Set all the way to the left and every student will be called on before any students are repeated. Pull it all the way back to the right so that a student can be called at any time. Even if he/she was just called. I like to set it in the middle to keep the students on their toes. Get the paid version so you can record correct and incorrect responses. After you have finished the lesson you can quickly send yourself an e-mail to view the results for later use.
