This study examines how reflective practices can be an effective strategy in enhancing in-service teachers' Technological Pedagogical Content Knowledge (TPACK). The participants were two English teachers in high schools in Indonesia who designed and implemented technology-integrated lessons after participating in a professional development workshop. Data collected from their reflective journals and interviews were analyzed using thematic analysis. Findings from the interviews and teachers' reflective journal revealed three reflective practices: reflection in, on, and for action. Reflective practices helped the teachers to describe and articulate their own experiences in teaching, learn from enacted experiences in the classroom, and apply learned practices in subsequent teaching. This virtuous cycle indicates that reflective practice is an essential mechanism for EFL teachers to become proficient in integrating technology in their teaching practices.
