The Biden administration has set a goal: a majority of public schools open "at least one day a week" by the 100th day of his presidency. But it's possible the country is already there — and decisions about when to reopen largely fall to cities and school districts, where administrators and teachers sometimes don't see eye-to-eye. Students are losing a lot of academic ground the longer their schooling is disrupted. Maine Public Radio's Robbie Feinberg reports on how one rural district is trying to reach students who haven't been showing up for online classes. This week, as the Centers for Disease Control and Prevention is expected to release new guidelines about how schools can reopen safely, three public school teachers weigh in: Mike Reinholdt of Davenport, Iowa; Maxie Hollingsworth of Houston, Texas; and Pam Gaddy of Baltimore, Md.
