LA Unified's iPad plan doesn't compute

[Commentary] It has been a year since Los Angeles Unified schools Supt. John Deasy proposed putting a tablet computer in the hands of every student in the district. At that time, there were numerous questions about how and whether this would work. Could first-graders really take care of such expensive equipment? Who would be held responsible if one of the devices was stolen, lost or broken, or if apple juice was dripped into the circuitry? How would the district keep high-schoolers off porn sites? And how much would all this cost? The district has forged ahead — 47,000 students have received iPads already, with a much bigger purchase planned soon — yet vital issues remain inadequately addressed. Given the many easily foreseen questions that have not been resolved, the board should require a more gradual rollout so that problems can be identified and addressed before it is too late to change course.
