I am a current classroom middle school math teacher (@mrschwen). I have created this app for my own classroom and use it on a daily basis with my Geometry students.
WiFli Response is a student response system that works within a teacher's Google Apps account. The student response link is permanent and allows rich feedback to help in directing instruction for individuals or groups in class. Data is presented in a visual dashboard and can be manipulated to identify students by name, correct answer, confidence or specific answer given. It can also be configured to identify what class is responding and what student has not submitted a response as well.
Answer types can include scored short responses such as numerical answers. Responses can be given by students on any web enabled device. Teachers can start and view question results from mobile or desktop applications.
