As students return to school, more states and districts are cracking down on cellphones. But not everyone agrees. On “Post Reports,” we hear how things look on the frontlines of this battle.Read more: A few years ago, Jennifer Rosenzweig’s high school students gave her a strange nickname: the “Bucket Lady.” That’s because Rosenzweig, an English teacher at Scarsdale High School in New York state, saw students increasingly on their cellphones, including in class, and having trouble focusing. Her solution? Have students drop their phones in a bucket before class. Today, Rosenzweig is no longer the sole phone cop at her school, which now has a caddy on every classroom door, with pockets that students drop their phones into as they enter.  New policies like this are spreading at schools throughout the United States, with pressure coming from teachers and parents who see phones as a distraction, an impediment to learning and a burden on students’ mental health.Host Martine Powers speaks with national education reporter Laura Meckler about the growing battle over phones in schools and the different opinions on the correct approach. Today’s show was produced by Emma Talkoff with help from Ted Muldoon and Rennie Svirnovskiy. It was mixed by Sean Carter and edited by Monica Campbell. Thanks to Karina Elwood and Chastity Pratt. Subscribe to The Washington Post here.
