English as a Second Language (ESL) teachers in Malaysia, as in many other countries, are anxious to exploit the potential of Information and Communication Technologies (ICT) to enhance the teaching and learning process. Given the increasing pressure exerted by technological developments on language education, it is important to understand the underlying factors behind teachers’ decisions regarding ICT. Egbert et al. (2002) state that few investigations have been conducted on computer-using language teachers’ development. According to BECTA (1999) the learning potential of ICT is not being realised, because many teachers are not familiar with ICT and do not use it in their teaching. This study investigates the present use of ICT among ESL technical school teachers in teaching, factors that affect the use of ICT and perceptions of their skills in ICT. The theory that frames this study is drawn from theories of learning. The model adopted is Davis’ Technology Acceptance Model (TAM) (1989) which provides a basis for determining ICT attitudes and factors affecting the usage of ICT in teaching. Data was collected via a questionnaire survey of ESL technical school teachers in Malaysia, and followed by semi-structured interviews with them. The questionnaire data was analysed using descriptive statistics and later triangulated with the interviews. The findings will be presented and elaborated upon in this paper.
