I think that interactive white boards are transformative. You can do so much more with them than a regular white board. You also aren't as confined to where you have to be such as over at your computer when you want to bring something up. Or even switching back and forth you don't have to go back and forth. You can do it all from one place, in front of the board.
In my opinion, white boards are worth the money because they provide students the opportunity to learn material in a visual and hands-on manner. They can be actively involved in the material they are studying by using the board's touch screen features.
"Interactive white boards" can play an important role in modern classrooms. They provide a new way for students to in fact be interactive. I think they allow for the students to potentially get out of their seat and take an active part in the lesson. This has been done with a typical white board, yes, but not quite with such depth and variety of these.
