Doug Peterson raises a great question regarding the long-term sustainability of remote learning. The curriculum, he observes, is changing. Just as math today no longer looks like the math we learned as students, so also computer programming has changed. In particular, we've gone from the days where we wrote programs on a computer and got results on the screen or printout. Today's computing involves working with robots or drones using languages like Logo on tools like Lego or micro:bit. And it's not just computing: the new math curriculum may use these sorts of tools. So when the student is at home, what does the parent do? "Unless Mom and Dad have the ability to run out to an educational store and buy it," a robot or manipulatives, "you’re left with a Plan B." What does plan B even look like? Nobody is to blame, writes Peterson, but there does need to be a plan.
