　　A

　　One of California’s poorest school districts, the Coachella Valley Unified southeast of Los Angeles, is currently rolling out iPads to every student. But, as with tablet efforts across the country, this one faces skeptics(怀疑)and obstacles(障碍). Some wonder if its projected benefits are being grossly oversold.

　　Darryl Adams talks about his school district’s latest project. “Everyone will have an iPad! ”he says with a broad smile. “It’s going to be exciting! ”He argues that school districts have often failed to inspire kids. Instead, he says, they’ve been teaching them how to take tests. “And that’s not what education is about. So for the first time in our history as a nation, I think in the world, we’re going to be able to personalize education, ”Adams says.

　　But some districts have publicly stumbled(绊倒)with their initiatives(为解决困难采取的行动). Los Angeles Unified students easily got around restrictions on their district-issued iPads: They simply deleted their personal profile info and then could surf the Web without restriction.

　　Coachella Valley is trying to learn from LA’s problems. It’s working to strengthen profile security and will block harmful and inappropriate online contents. Some security measures should be a classroom management issue. Kids should have digital citizenship and proper use of the iPad.
