An interesting article at The Conversation concludes that: perhaps it’s time for the pen to say it’s farewells for regular use in the classroom, replaced by the smartphone and relegated to ‘writing time’, just like we used to have “computer time” back when I was a kid. I agree that, in classes where all the students and teachers have both a smartphone and affordable bandwidth always available, smartphones may do much more to improve learning than it usually happens in such classes.
