The digital part isn't really the important part. Indeed, the original article subtitle is "It’s Not Just About the Laptops". Some key points from TFA:

* This is not about the technology [...] It’s about changing the culture of instruction.

* Laptops [...] let students work at their own pace or in groups.

* Mooresville frequently tests students in various subjects to inform teachers where each needs help.

* Emphasis goes to identifying students who are only a few correct answers away from passing.

* Students collaborate in small groups with the teacher swooping in for consultation.

* Teachers apportion their time based on the need of students.

* Students adapted to the overhaul more easily than their teachers. Layoffs in 2009 and 2010, of about 10 percent of the district’s teachers, helped weed out the most reluctant.

* Technology would actually allow for more personal [...] interaction with students.

* You have to trust kids [...] teachers have to be willing to give up control.

* Culture of collaboration among staff and kids.

* You have to realize that students learn best at their own pace.
