My Take
I feel this can be an effective learning tool if you understand all of the features that go along with it. I feel it is useful and can replace a white bird, also students can add pictures, audio, and writing to their blank page.
How I Use It
I would use it instead of an actual whiteboard, students can use it to practice spelling and writing or math problems. You can also give students problems and have them work on them if you have a class set of iPads.
