In Finland, when Nelli Louhivuori saw her elementary schoolers languish through reading, she invented a new kind of recess. Every Monday, she took her students on a little field trip to “library recess.” There wasn’t a set list of books—they got to choose their own. They got to know the librarians—who in turn got to know their interests and started stopping by Nelli’s classroom with teasers on relevant new releases.
