It’s back-to-school time, which, for millions of families across the country, means a return to bedtimes, shopping for school supplies, and frantic efforts by kids to finish their summer reading. On this episode, we explore how our fast-changing world is transforming learning and life inside the classroom, from the lingering effects of the pandemic, to the impact of generative AI tools, to the pressures of “Ivy League fever.” Interviews with host Maiken Scott: When COVID-19 hit the U.S. in March 2020, schools across the country closed down — and stayed closed — as part of an effort to stem the pandemic’s spread. At the time, it seemed like the right move for public health — but according to investigative reporter David Zweig, the basis for those closures was a lot shakier than the public knew, the benefits less clear, and the impact on kids more profound than we imagined. He joins us to discuss his new book, “An Abundance of Caution: American Schools, the Virus and a Story of Bad Decisions.” We talk with education reporter Holly Korbey about how the adoption of new technologies — from Smartboards, to laptops, to ChatGPT — are transforming the classroom, and what science has to say about whether those changes are good or bad for learning. Korbey writes The Bell Ringer, a newsletter on the science of learning.

In the summer of 1976, when 2,000 people came to Philadelphia for a national convention of the American Legion, a strange illness gripped hundreds of attendees, and more than 30 people died. Symptoms included cough, shortness of breath, and fever. Was it a virus, bacteria, some sort of toxin? A major investigation was launched by the CDC — and the gathering in Philadelphia became forever tied to one of the greatest medical mysteries of our time.    Almost 50 years later, reports of Legionnaires' Disease are in the news again. Reporter Elana Gordon tells the story of how scientists — with some serious shoe-leather detective work and a scientific breakthrough — tracked down the origin of this mysterious airborne illness.  On this episode, we listen back to her reporting from 2016: Audio Time Capsule: The discovery of Legionnaires’ disease.
