Yale professor Alexander Nemerov found a great way to get students to pay attention: lecturing in a Wi-Fi dead zone. Glenn Fleishman, writing for The Economist:
The good professor is no Luddite. He realises that a request to turn off the hall's Wi-Fi routers during a class may meddle with other nearby needs. (And it would in any case be useless in blocking mobile 3G and 4G signals.) Some students, he concedes, clearly use the internet to enhance his lectures, looking up artwork he discusses to get a closer or different view, or taking notes. But some engage in less pertinent online activities. Dr Nemerov debated with himself whether to note the signal blockage in his course syllabus but ultimately decided to leave students to discover this for themselves.
