摘要:The teaching profession has been considered as a highly respected job in some developed countries for bringing significant impacts on the country’s national growth. Therefore, teachers are generally being illustrated into some animations,videos,or pictures on websites and other internet sources. Thus,this research is aimed to investigate how teachers’ identity is represented on Instagram. Ten Instagram posts related to this issue with the help of Instagram hashtag about #teacherlife were used as the data to get the finding. The research applied the theory and method of Critical Discourse Analysis (CDA) with the perspective of multimodal discourse analysis and social semiotics. The data were analyzed by using the signing model of Saussure. Initial coding was also used to analyze the data. The finding revealed four big results,they are: the teacher’s responsibility, teachers’ commitment,teachers’ authority,and teachers’ need for recognition. Furthermore,identity is affected by some factors,where different contexts of teachers may have different identities.
