School districts are notorious for having just enough tech staff to keep end users functional, but absolutely no staff to "think ahead".
This district needs tech leadership that can look forward at technologies that may or may not be useful, then it needs implementation and testing staff to make sure those tech plans become reality.
I suspect this district thought they could simply sign a contract with Pearson - and like magic, the tech would deploy itself and the staff would automatically learn the tech and integrate it into the curriculum.
Our schools have moved away from iPads - management tools are sparse and the tech simply isn't that great in the classroom. We've settled on Chromebooks. The management tools are great, the devices are cheap - and Google Apps is free for schools and non-profits.
If LASD had competent technology leadership, they would have known about all of these challenges and limitations during their pilot phase - before dropping a ton of coin on a half-baked solution.
