摘要：http://dx.doi.org/10.5007/2175-8026.2016v69n1p141 The purpose of this study was to develop and test the reliability and validity of an instrument to evaluate the extent to which software programs teach English as a Foreign Language and/or Second Language (EFL/ESL) pronunciation following the principles of the Communicative Approach (Celce-Murcia et al, 2010), thus having the potential to develop English pronunciation. After the development of the instrument, 46 EFL/ESL teachers used it to analyze an online version of the software program Pronunciation Power 2 . The responses of the participants were submitted to statistical analysis and the validity and reliability of the instrument were tested. The good reliability indexes obtained in this study suggest the instrument has some degree of validity for evaluating how well an ESL/EFL pronunciation teaching software program potentially develops English pronunciation.
