GUILDERLAND — As the debate rages across the country and around the world over whether digital learning should supersede traditional teaching, Natalia LeMoyne is unperturbed.

Executives in Silicon Valley pay hefty tuition fees to send their children to a Waldorf school that banishes computers. Every student at a poor public school was given an iPad, yet test scores remained low. In a recent debate at Columbia University “More Clicks, Fewer Bricks: The Lecture Hall is Obsolete,” a professor who believed online courses could not replace the intimate interaction between students and their teacher argued against a professor who taught online and said he could reach more students in an online course than in 40 years on campus; the audience voted — electronically — to declare the clicks the winners of the debate.
