In Abiansemal, a rural district north of Denpasar and west of Ubud in Bali, the Ayung River cuts through rocky gorges, winding past rice fields and jungle. Down by the river, a spread of bamboo pavilions rises in a hug of palm trees and thick bushes, their wide thatched roofs fanning out like giant conical hats. From above, the complex gives off the vibe of an eco-retreat in the middle of the jungle. But beneath the thatched roofs are open-air classrooms, designed to nurture young minds through an unconventional curriculum that could reimagine education as we know it.
