A Moose Jaw teacher has won $15,000 worth of computers and other technology for her school as part of a national contest.

Shelly Wright, who teaches at Cornerstone School, was one of three winners in the classroom video challenge.

Wright is the western Canada winner of the competition sponsored by the MindShare Learning Report, an educational technology magazine.

The eastern and central Canada winners teach in St. Stephen, New Brunswick and Dundas, Ontario.

Wright's students used social media — including Twitter, Facebook, Flickr, YouTube and Tumblr — for a project examining child trafficking in the developing world.

Winners receive a computer, video camera, digital projector, electronic whiteboard, software, training and other technology.
