Listen, I'm all about researching the effects of traditional and non-traditional methods. But this one seems like a no-brainer. It doesn't sound like they were studying the effects of texting on classroom interaction and engagement. Seemingly, they were studying off-task behavior. And off-task behavior will lead to lower GPA's. Are we under the impression that merely having technology in the classroom will lead to smarter students?
I have an old Atari 2600 in the garage. I'll move it to my classroom cabinet and watch the learning begin!
