RONG DOMRIEX, Cambodia — Tel Im, a barefoot 13-year-old, sat cross-legged on a bamboo bench, eager for her reading lesson.
"Please turn to Lesson 33," said a woman’s voice rising from a Sony cassette player powered by two wires clipped to a car battery. The tape was the closest thing to a school in this village shaded by banana trees, where water buffaloes meander in from the lime-green rice paddies. Im and her classmates flipped to Page 134 for a passage from the New Testament.
