Nearpod is an interesting new service that teachers can use to create, deliver, and monitor student use of educational content on iPads and iPods. Nearpod is still in a closed beta (they are looking for pilot schools), but what I have gathered about it so far indicates that teachers use it to create quizzes, polls, Q&A activities, and instructional presentations. Teachers using Nearpod to deliver quizzes and polls can look at students' responses individually or in aggregate.
Embedded below is a short introduction/ promotional video for Nearpod.

Applications for Education
Nearpod could be a good tool for teachers to create and deliver customized content to their students. The feedback mechanisms may allow you to quickly get a sense of your students' comprehension of the lessons that you deliver.
