Yesterday, we were using our new, district-mandated Chromebooks (which are mini-laptops functioning half like a Mac and half like a PC, with a touchpad but no mouse) to take the district-mandated SAGE test, a 9th grade boy clicked the wrong tab at the end of the test and then couldn't find his test score. He raised his hand, and I came over to help him.
I leaned over the Chromebook and said, "It's easy; just hit the 'back' button here."
I tapped the button with my finger. Nothing happened. Frustrated, I tapped three more times. No results. Both the boy and his neighbor watched me, saying nothing.
It took a good 15 seconds of tapping before I rolled my eyes in disgust.
"It's not a touchscreen. Duh," I said -- and used the touchpad to move the cursor to tap the back arrow.
Then the boys laughed.
I suspect I may not be getting enough sleep at night.
