WASHINGTON, DC – NOVEMBER 21: Technology coach and teacher Milton Bryant (right) shows 5th graders the initial online setup of exercises at Ketcham Elementary school in Washington, DC on November 21, 2014. The kids then went to their own computers for online learning. The school is one of the first in the District public school system to move toward blended learning in which students spend part of the day learning with teachers and the other half learning online. Ketcham is one of 10 DCPS schools who saw significant improvements in their test scores. They plan to expand the model to four more schools this year.
