Back to school: Hybrid learning starts for select Philadelphia School District students WPVI Monday marked the first day of hybrid learning for pre-kindergarteners through second-graders at 53 Philadelphia public schools. That includes Hon. Luis Muñoz Marín Elementary in North Philadelphia. "They are ready and learning in classrooms right now. They are attentive, they are navigating the virtual space with other partners that are still at home on Zoom," said Principal Amanda Jones. Teacher Mandie White is excited to see her returning students. "I told my husband, 'I'm so glad to be able to talk to someone besides you!'" she joked.
