Class, a new teaching tool by NoteBear, is a real-time feedback tool for teachers or professors. A simple rating system allows professors to keep a pulse on how many students are following the subject matter, organize student questions, and even poll students to real-time test their understanding. My parents are both professors, and I find this product very interesting—I can tell you my folks would adopt it in a heartbeat if it locked their student’s screens to stay on subject and off of Facebook or Snapchat! As is, they might need a little convincing—but the polling ability might just win them over!
