The present study aimed to investigate the challenges and barriers encountered by ESL teachers when they implement technological tools in writing classroom. It also explored teachers' perceptions towards integrating technology in writing classroom. The study involved observing a number of writing classes from different levels at an English Language Institute at a southwestern university in the United States. Next, an interview was conducted with one of the observed teachers to enquire about implementing technology in the classroom and reasons behind possible challenges. The study revealed some challenges that hindered or prevented teachers from applying technology in writing classroom. Such challenges were technical problems, students' attitudes towards using technology, lack of time, lack of computers and other devices, and lack of technical support. Moreover, the study showed that teachers had positive perceptions toward using technology to facilitate teaching process. Pedagogical implications and solutions to overcome technical issues are provided for ESL/EFL writing teachers and policy makers.
