%J IJEE (Indonesian Journal of English Education) %T INSTAGRAM TO LEARN ENGLISH VOCABULARY: A STUDY OF INDONESIAN NON-ENGLISH MAJOR UNIVERSITY STUDENTS %A Thesalonika Dwi Wardhani Baruti Puspita %A Adaninggar Septi Subekti %X This study aimed to investigate the attitudes of non-English primary university students in Indonesia on using Instagram for vocabulary learning and to find out the students' views of learning English vocabulary using Instagram. Considering the popularity of Instagram among Indonesian university students and the scarcity of such studies involving non-English primary students, investigating their use of Instagram for English vocabulary learning can be worthwhile and relevant. The study involved 213 student participants who were Instagram users in an online survey and six in online interviews. The survey found that the participants generally had positive attitudes toward using Instagram for vocabulary learning. However, the study found the participants' somewhat ambivalent views through the Thematic Analysis of the interview data. Students reported consciously learning new isolated English vocabulary from English captions on Instagram. They unconsciously acquired isolated English vocabulary from photos and videos on Instagram. However, Instagram was not helping in obtaining vocabulary in contexts as it gave a limited content explanation. The findings could help teachers to make an informed decision when using Instagram in the instructional process, optimizing its strength and potential. %P 106-125 %K English vocabulary; Instagram; vocabulary learning; isolated vocabulary; vocabulary in context %V 10 %D 2023 %R doi:10.15408/ijee.v10i1.26969 %L katalog9095 %I UIN Syarif Hidayatullah Jakarta %N 1
