Abstract
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.
Highlights
The nature of language as a system implies that a language is composed of two systems: a system of sounds and a system of meaning
A close examination of the differences in the mean scores between pre- and post-tests, as seen in Table 3, we found that the differences between pre- and post-tests were quite high, 22.42 for English as a foreign language (EFL) learner’s knowledge of the target English phonemes and 19.61 for EFL learners’ ability to pronounce the target English phonemes
After performing a series of paired-sample t-tests for the data of pretest and posttest, the results of data analysis have shown that there was a significant difference in the mean scores between the pre-test and the post for both of the investigated variables, t(df =30) = 22.07 at p < .01 and t(df =30) = 44.17 at p < .01 respectively
Summary
The nature of language as a system implies that a language is composed of two systems: a system of sounds and a system of meaning The relationship between those two systems is very important because in human verbal communication meaning or message is conveyed or received primarily through sounds or vocal symbols. These vocal symbols are expressed in the form of words (vocabulary) and arranged in certain grammatical structures (grammar). In terms of oral language, there must be message (meaning), grammar, vocabulary and pronunciation Another feature of human communication is that language is a cultural transmission.
