So when you first go to Gosoapbox, you need to sign up for an account, its a quick and easy process, but thats all you will need, no student accounts needed. For any of us in the classroom, we all know how great that is.
After you sign in, the first thing you will do is create an event. Depending on how you run your classroom, you may just want to label it as the date. After you are done creating the event you are given a nine digit code, which will be used later for the students to join your event.
Now the creators of GoSoapbox describe it as "GoSoapBox is a web-based clicker tool used by educators around the world to keep students engaged and gain real-time insight into student comprehension." And I would say that is how it goes. Students go to the same login as the teachers, but instead of logging in, they enter the event code. Once they are asked to enter a nickname. Once they have done that you are able to see how many of them are online. In their interface they have a I understand button and a I am confused button, if they click on the I am confused button, it will flash red on your interface and you can see exactly how many of them are confused. This is all done without disrupting the flow of the lesson.
That alone would make a tool to think about using in the classroom. But as a teacher you have an option to embed a quiz, a poll, or a discussion. Now after you create them they are locked, you click on the the lock for and it immediately becomes available for students. When you are done, you can easily download a spreadsheet with all your data.
Now it is not all perfect, I had a couple of students get stuck after they entered the access code, but a quick page refresh and they were part of the event.
