Many teachers and schools are snapping up iPads, especially since the iPad2 has dropped the price of the 1st gen. How could you use the iPad in class as a teaching tool? Alive in Five shares a nifty app called Splashtop ($4.99) from the iTunes store that allows you to use your iPad as a virtual slate of your computer. If your class computer is used to display, via projector, then you can explore web content, open apps, and use the iPad as a slate device. The benefits are mobility and a cool factor your students will enjoy.
