Abstract This research aimed to explore the application of student-centered learning in the teaching of English language at To Ky Secondary School, as well as the effects of this method on students’ learning engagement. This research was based on a case study design, where 40 students and three teachers of English language at the school formed the participants. Quantitative and qualitative data collection methods, including questionnaires, observations, and interviews, were used. Quantitative data was analyzed using descriptive statistics, while the rest was analyzed through thematic data analysis. From the research, it was evident that the use of student-centered learning, including activities such as group discussions, role plays, pair work, and project work, had a significant effect on students’ learning engagement. Students had positive attitudes towards interactive learning activities, especially on improving their speaking skills and learning motivation. However, teachers noted that the application of student-centered learning was effective in promoting learning engagement, but there was a need to consider the large class sizes and varying students’ competence.
