How I Use It
I have used GoSoapbox with students and with staff as a way of engaging them in a lesson, pre-testing and post-testing their knowledge and creating a way for students to provide me with live feedback. The "Confusion Barometer" allows teachers to see in real time if students are "getting it" or if they need more support or explanation. Students love being able to ask questions anonymously and being able to see instant survey results.
This is my "go-to" student response tool. Its many features allow it to be used as a simple Q & A, quiz or survey but also allow teachers to deepen the experience by conducting open and moderated discussions. It's a great way to allow a student thinking time to respond when he/she is less comfortable verbalizing and raising his/her hand.
As a teacher I find the ability to review student responses very helpful in determining how students are understanding the material and targeting their need for follow up instruction before an assessment. More options for multimedia for questions would be nice, as well as the ability to make the quiz competitive like other sites like Kahoot.it do, but overall I find it the most capable free student response tool out there.
