This study attempted to investigate the types of motivation (integrative or instrumental) that Thai
English majors at Asia-Pacific International University had toward the learning of the English language,
and the correlation between the students’ learning motivation (integrative and instrumental) and their
academic achievement (GPA). The statistical analyses revealed that these students had both high integrative
and instrumental motivation to learn English. Their integrative and instrumental motivational levels were
fairly close although their instrumental motivation was found to be slightly prominent.
