The advancement of technology has led to a paradigm shift in the educational system, especially in classrooms. Technological tools have been used for language teaching in recent years, and it is proven that the use of technology enhances teaching and learning experiences. However, the researchers lamented the lack of use of technology by pre-service to teach English as a second language (ESL). This study aims to investigate factors that influence pre-service teachers’ intention of using technology for teaching ESL. This research applied the Unified Theory of Acceptance and Use of Technology (UTAUT) with some modifications to the constructs. Using simple random sampling, this study distributed questionnaires to 257 ESL pre-service teachers in Malaysia. Confirmatory factor analysis (CFA) and structural equation modelling (SEM) were used to analyse the data. The findings showed that technological, pedagogical, and content knowledge (TPACK) had a significant positive effect on the intention to incorporate technology in teaching. This study provides knowledge on the factors that influence ESL pre-service teachers’ intention to use technology in the classroom. It is hoped that this study can provide information for teacher training institutions to develop strategies and a new framework to address pre-service teachers’ concerns in technology utilisation for teaching ESL. As a conclusion, further study could be conducted qualitatively to better understand the subject matter.
