Welcome to Revise and Resubmit, the podcast where we break down groundbreaking research and ask the questions no one else dares to.Imagine a bustling market in Kolkata. A young boy, no older than ten, calculates the price of six mangoes faster than you can reach for your calculator. Now picture a classroom nearby. A student, pen in hand, struggles to solve a similar math problem on paper. Both children are smart. Both have been exposed to numbers their entire lives. Yet, their skills do not seem to transfer across these two worlds. Why?Today, we dive into a fascinating study published inNatureby Abhijit V. Banerjee, Swati Bhattacharjee, Raghabendra Chattopadhyay, Esther Duflo, Alejandro J. Ganimian, Kailash Rajah, and Elizabeth S. Spelke. Their research, conducted in India, uncovers a striking divide: children who sell in markets can handle complex arithmetic in real-life situations with ease—but when presented with the same math in an abstract school format, they struggle. Meanwhile, school-going children excel at textbook math but flounder when asked to apply it outside the classroom. What does this mean for education? And more importantly—how can we bridge this gap?Is our education system failing to connect learning with lived experience? And what if the way we teach math is fundamentally flawed?A big thank you to the authors andSpringer Nature for bringing this crucial research to light.
