Heat isn't just a nuisance to students; it's a barrier to learning

Less than a month ago, a heat wave in the Midwest forced schools in Minnesota, Michigan, Illinois and other states to cancel classes or dismiss students early. To help with the heat, officials in St. Paul gave students water bottles and delivered hundreds of fans to schools, most of which lack air conditioning.

This example, though extreme, points to a larger pattern. Most teachers and administrators know that sweltering classrooms are both physically dangerous for students and not conducive to learning. Overheated students and teachers become fatigued, lose focus and find it hard to do their educational work well.
