I went through high school in the mid 00s, and just recently graduated from college. Every classroom I&#x27;ve been in for the past 10 years has had a &quot;smart board&quot;, which is basically a giant whiteboard with touch recognition. They have &quot;markers&quot; you can pick up and write on the screen with, and an eraser that lets you erase what you&#x27;ve written. They were very successful, and incredibly useful- plus teachers could save the images they drew and then put them up for the class to access later.<p>Where I work now we have one as well- except instead of a projector it&#x27;s just a big LCD touchscreen.
