image of classroom display technology and education touch panelKids today have it all: the cell phone, the iPod, the iPad, the internet, digital cameras, video games, laptops – ahhh!!! With all this stimuli, teachers have to battle to win the ever-decreasing attention spans of their students. And any teacher knows the statistics of how students learn: most of what they get their hands on (tactile learning), some of what they see (visual learning), and little of what they hear (aural learning).
