This document analyzes the effects of staff development trainings on teachers' use of technology in the classroom. It reviews literature on barriers to implementing technology after trainings. The author conducted surveys, focus groups, and observations of teachers involved in an education technology grant. The findings showed that most teachers attended trainings and implemented some new skills, but did not use technology to its fullest potential. The implications are that districts should provide better follow up support to help teachers fully utilize technology after trainings.
