Technology has the potential to enhance learning; however, generic technocentric strategies in schools have exacerbated barriers to technology integration in the classroom. Teachers are key to successful technology integration in schools.

This mixed-methods study investigates technology use by teachers and pupils in the A-level history classroom in Northern Ireland, through the lens of Ertmer, P. 1999.

A number of impediments to effective technology use in the classroom were identified and strategies to minimise these barriers are recommended.
