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 teacher’s 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.

Technological Pedagogical Content Knowledge (TPACK) is a framework to develop the theory to practice in teaching with technology. Therefore, the teacher, as a practitioner of TPACK implementation, has a responsibility to implement the knowledge effectively. This study investigates the meta-cognitive awareness produced by teachers who participate in TPACK lesson design workshops. This process involves some reflection tools, focus group discussion, and reflective journal as a platform for doing the reflection. This study documented teachers’ stories during three interviews as they created their TPACK lesson design. The detailed data was from three Indonesian teachers. Those teachers participated in the process of research from the professional development workshop to the focus group interview. The data indicated the details of their experience in reflecting and determining on their professional knowledge. These findings show that during the reflection, the teachers start to realize each aspect of TPACK in three stages. These findings are useful for the government to establish professional development workshops in the technology education field. The researcher explored the implications of this analysis for teachers to effectively design the lesson and future researchers.
