This research aims to find out how teacher’s use multimodal texts in English
language learning and the challenges faced during the process. This research used
a qualitative approach with a case study method conducted at MAN 1 Banjarmasin,
specifically in class XI Advanced Level 3. Data was collected through observation
and interview of one teacher and six students. The results showed that the teacher
used various multimodal text such as YouTube videos, Students’ worksheet,
WhatsApp, and Google Form to improve students' understanding of English
materials. Although their use proved effective in increasing students' motivation
and engagement, teacher faced several challenges, such as limited technology
facilities, unstable internet networks, and suboptimal digital skills. On the students'
side, challenges include a lack of interest in uninteresting videos and distraction
when using digital devices. Therefore, adequate facility supports and technology
training for teachers are needed to optimize multimodal text-based learning.
