TECHNOLOGIES: Digital Note-Taking

OneNote: All your notes—in one place and with you, anywhere. OneNote is a digital notebook for your to-do lists, lecture and meeting notes, vacation plans, or anything you want to organize or remember. Type or jot down notes, record audio or snap a picture and OneNote saves it. Your notes sync across your devices so you can access them wherever you go. And you can easily share your notes with others. Here is a OneNote Tutorial.
