Ziplet is a service for gathering feedback from your students in a variety of ways. The simplest way is to create an exit ticket by using one of the dozens of pre-written questions provided by Ziplet. Back in July I published a video about how to use Ziplet. Since then it has been updated to no longer require students to have accounts to respond to exit ticket questions. Now your students can simply enter an exit ticket code that you give to them before they answer the question.
What Ziplet offers that is somewhat unique is the option to respond directly to individual students even when they are responding to a group survey. The purpose of that feature is to make it easy to ask follow-up questions or to give encouragement to students based on their responses to a question posed to the whole group.
Applications for Education
Ziplet fits in a gap between tools like Kahoot and Google Classroom. For that reason it could be a good tool for engaging students in discussions about assignments, course topics, or the general feeling of the class. Ziplet does offer a Google Classroom integration as well as an Office 365 integration.
