Many studies worldwide have found correlations between
students’ exposure to English outside the classroom and students’
English vocabulary and oral proficiency. However, these studies
have mostly been conducted with ESL (English as a Second
Language) high school students or older students, while primary
school students in EFL (English as a Foreign Language) countries
have not been well documented. The study aimed to (1) investigate
whether there are any correlations between Extramural English (EE)
and listening and reading proficiency of Vietnamese EFL primary
school students, and (2) determine their experience with EE. The
participants were 101 Vietnamese elementary school students. Both
interviews and questionnaires were used to collect information
regarding students’ extramural English outside of the classroom and
their experiences in EE activities. An English proficiency test
including listening and reading was employed to examine students’
listening and reading. Findings showed that there was a correlation
between extramural English and EFL primary students’ listening and
reading proficiency. Most students participated in two main EE
activities: using English game-based learning applications and
surfing the internet. The study suggested different techniques, some
online games, and materials to support learners in acquiring a new
language actively, and teachers could encourage more students to
practice extramural English outside the classroom.
