This case study examined three teachers from different senior high schools in Indonesia of their beliefs about teaching writing with the TPACK framework and their classroom practices. A semi-structured interview was administered to explore their beliefs, while classroom observations focused on their classroom practices. The results demonstrated similarities and differences among teachers’ beliefs about learning objectives, teacher’s role, and assessment, while in classroom procedure and instructional material, teachers shared identical beliefs. Indeed, there was a majority of consistency between teachers’ beliefs and classroom practices of teaching writing with the TPACK framework.

Then, this study may provide references for teaching writing with the TPACK framework that can adequately be applied during the COVID-19 outbreak and new normal.
