Podcast: When the Algorithm Reaches Its Limit, Who Steps In?

What happens when a tool works exactly as designed, and still falls short? David Webb, an international school teacher in Jakarta, India, spent a year building LibraryAid, an AI-powered book recommendation app without a computer science background, and discovered precisely where an algorithm ends and an educator begins. Gabe Nitro, a high school teacher in California, watched his school embrace Yondr phone pouches as a solution to classroom distraction and found himself doing the math on how much instructional time the enforcement itself was consuming. Two tools, two classrooms, one question: when the technology reaches its limit, who steps in?

A Year of Vibe Coding, One Unexpected Lesson

Webb describes the process of building LibraryAid through vibe coding, describing what he wanted in plain English and letting AI tools write the code, spending a year marked with near defeats and small breakthroughs. The app now tracks roughly 30 factors to match students to books in their own school library catalog. One student reading two grade levels behind made three times the average reading progress after the app connected him to a book series he loved. Yet Webb found himself returning, again and again, to a line he wrote in his piece for EdSurge: the algorithm had done its job, and what the child needed next was a conversation with a trusted adult. Join us on This Week with EdSurge where we ask what Webb learned about reading, motivation, and the irreplaceable role of the teacher in the loop.

The Pouch Solved One Problem. Then What?

Gabe Nitro is a high school teacher in California whose school uses Yondr pouches to lock students’ phones away for the school day. He is not arguing for phones in classrooms. He is arguing that the pouches are consuming the instructional time they were built to protect, with enforcement eating as many as 49 minutes per school day before a single lesson begins. A study from the National Bureau of Economic Research found no statistically significant impact on standardized test scores for high schoolers in English, a finding Nitro shared with colleagues who told him they still wanted the pouches anyway. His piece for EdSurge raises a harder question: when the tool does not deliver what was promised, what keeps us holding onto it?
