In Peru, a Pint-Size Ticket to Learning

The XOs that Peru is buying will be distributed to pupils in 9,000 elementary schools from the Pacific to the Amazon basin where a single teacher serves all grades, Becerra said.

Although Peru boasts thousands of rural satellite downlinks that provide Internet access, only about 4,000 of the schools getting XOs will be connected, Becerra said.

Negroponte says One Laptop is committed to helping Peru overcome that hurdle. Without Internet access, he said, the program is incomplete.

Teachers will get 2 1/2 days of training on the laptops, Becerra said. Each machine will initially be loaded with about 100 copyright-free books. Where applicable, texts in native languages will be included, he added. The machines will also have a chat function that will let youngsters make faraway friends over the Internet.

Critics of the rollout have two key concerns.

The first is the ability of teachers -- poorly trained and equipped to begin with -- to cope with profoundly disruptive technology.

Eduardo Villanueva, a communications professor at Lima's Catholic University, fears "a general disruption of the educational system that will manifest itself in the students overwhelming the teachers."

To counter that fear, Becerra said, the government is offering $150 grants to qualifying teachers toward the purchase of conventional laptops, for which it is also arranging low-interest loans.

The second big concern is maintenance.

For every 100 units it will distribute to students, Peru is buying one extra for parts. But there is no technical support program. Students and teachers will have to do it.

"What you want is for the kids to do the repairs," said Negroponte, who believes such tinkering is itself a valuable lesson. "I think the kids can repair 95 percent of the laptops."

Tech support is nevertheless a serious issue in many countries, Negroponte acknowledged in a telephone interview.
