This study investigates the effectiveness of Quiz-Demonstration-Practice-Revision (QDPR) in improving EFL learners' pronunciation of English. To achieve the goal, the present researcher conducted a one-group pretest-posttest design. The experimental group was selected using a random sampling technique with consideration of the inclusion criteria. Through the treatment process, the group was taught using QDPR in which the student participants were explained how to pronounce the target English phonemes in their first language (L1). The student participants were given an oral test and a written test related to the target English phonemes and a questionnaire on QDPR. The collected data were analyzed using paired-sample t-tests to examine the significant difference in the means scores of their knowledge of pronunciation and their ability to pronounce the target English phonemes, and simple regression tests to investigate the effectiveness of QDPR learning model to their knowledge of pronunciation and their ability to produce the target phonemes. The results of data analysis have revealed that (1) QDPR was significantly effective in improving EFL learners' pronunciation, and (2) QDPR significantly helped the students improve their pronunciation. Thus, QDPR can be an alternative model to English pronunciation instruction in EFL classrooms.
