This will be perfect on accessing students and figuring out how the things you are teaching are being received. It is pretty self-explanatory with the above description on how it could be beneficial.
This will be beneficial because the students would be able to access assignments from home. You could use it for more than just assignments though and offer extra readings or even take home quizzes.
As a teacher this would be another great assessment tool but also a tool that gets the students engaged in the classroom. It is always nice to take even a few minute break as a student and try something new such as taking a poll.
This would be a great app to mix things up for teachers even for students to use for an assignment if desired. I feel if we are using technology in a classroom we should be using it to mix things up for the students and thats what using this app does.

You could use this as a teacher to share current events or even get the students to use it for projects with you. It will be especially fun to use at the elementary level with students.
