LAKEVILLE — Lakeville school superintendent Lisa Snyder said she was happy with a report that shows the district’s investment in technology is paying off — but she is not surprised.

A new iLearn Research report says 23 of the more than 30 classrooms or programs that did research on new iPads last year showed an increase in student engagement. Twenty-four reported that student motivation went up, and 20 saw gains in learning.

“This is innovation at its best and I’m really excited about that,” said Roz Peterson, school board chairwoman.

Trish Harvey, the district’s digital learning coordinator, said classes that reported no gains either saw no change or had teachers who were reluctant to attribute progress only to iPad use. No one reported negative results, she said.

Teachers who wanted iPads had to apply for an iLearn grant from the district in 2011. A total of 1,900 iPads were distributed and 108 teachers were involved in using the devices.
