This study examined the predictive power of teachers' perceived usefulness (PU), perceived ease of use (PEU), behavioural intention (BI) to use personal response system (PRS) and computer experience (CE) on teachers' acceptance and attitude towards using PRS in improving communicative competence in the classroom where English is taught as a second language (ESL). Seventeen teachers constituted the sample for the study. A self-report questionnaire and a semi-structured interview guide were used for data collection. Results indicated that teachers were generally positively disposed to integrating PRS in ESL classroom. Moreover, teachers' disposition was not significantly dictated by gender. Except for CE, constructs like PU, PEU and BI showed significant positive correlation with attitude to PRS. The results of regression analysis indicated that the set of variables combined to predict teachers' acceptance and attitude towards using PRS. Relatively, PU was the potent predictor of the dependent variable.
