Enhancing Pronunciation Skills of Diploma Students at Bangladesh University of Business and Technology through Oral Drilling: A Comparative Study of Pre- and Post-Exposure to Accurate English Sounds among ESL Learners

The purpose of this study is to investigate the efficacy of oral drilling activities for improving phonetic skills at the diploma level at the Bangladesh University of Business and Technology. Data were gathered from 200 Bangladeshi students who were purposefully chosen, who speak Bangla as their first language, and who utilize English as a second or foreign language for academic purposes using qualitative methodology. A self-developed Likert-scale structured questionnaire was used to analyse students’ understanding of their learning experience, and pre- and post-usage pronunciation tests were conducted in conjunction with reading exercise tests for phonetic improvement. This study provides important insights into ESL pedagogy in Bangladesh and has the potential to shed light on ODA as a didactic approach used in EFL contexts, which offers more appropriate curriculum-based implications for oral practice that may improve the Pronunciation skills of students.
