According to this article from the LA Times. From the piece:
“Teachers reported not being able to connect to the Internet in some classrooms. Students bypassed security measures and surfed prohibited websites. Parents aren’t sure if they’re liable if the $678 tablets get lost or break. District directives have been misinterpreted.”
The latest: Students from three high schools — Angelou, Roosevelt and Westchester — have been told to surrender their iPads until further notice. Students elsewhere aren’t being allowed to take them home.
