This finding and others were released this week by PBS LearningMedia in a December 2011 survey of 500 teachers who work in the U.S. The estimated sampling error rate is plus or minus 4.4 percent.
Only 22 percent of responding teachers said they had access to the right level of technology in their classroom.
PBS LearningMedia is a digital content service for educators and is operated by the Public Broadcasting Service.
