Résumé:
The overall objective of the current study is to investigate the effectiveness of using English
subtitled movies as a successful vocabulary building material. The study aims also to explore
secondary school students’ perceptions towards the use of ESMs for learning English in
general and vocabulary in particular, as it attempts to derive their suggestions to better
improve vocabulary learning through ESMs. To achieve the study aims, the researchers
adopted the quasi-experimental approach using pre-post tests on the target vocabulary. The
sample study consisted of 32 second year foreign languages students at Saadi Seddik
Secondary School (Tebessa). A selected movie with English subtitles was used in teaching
the experimental group, while the traditional method was used in teaching the control one
during the second term of the academic year 2019/2020. The paired sample t-test was used to
analyze the findings. A questionnaire was administered to the experimental group students to
explore their perceptions after the treatment. The collected data from this questionnaire were
analyzed quantitatively and qualitatively. The study findings revealed that using ESMs has a
significant effect on secondary school students’ vocabulary development. The findings also
pointed out that secondary school students have positive perceptions towards the use of
ESMs for learning English in general and vocabulary in particular as they provided some
important suggestions to better improve vocabulary learning through ESMs. Based on the
findings, the study recommended the necessity of implementing ESMs in secondary schools.
