PBS LearningMedia announced today findings from a national survey of U.S. teachers grades pre-K-12 that sheds light on the rising role of technology in America’s classrooms, as well as barriers teachers face to accessing the “right” digital resources. The vast majority–91%–of teachers surveyed reported having access to computers in their classrooms, but only 22% said they have the right level of technology.  Nearly two-thirds–63%–of teachers cited budget as the biggest barrier to accessing tech in the classroom. In low-income communities, this is an even greater challenge, as 70% of teachers reported it as the greatest obstacle.
