This article aims to investigate what kinds of Professional Development (PD) activities done by Indonesian professional English teachers in developing their pedagogical competence dealing with teaching implementation as well as to identify how those activities contribute to their competence development. This qualitative study was done in two stages namely subjects selection and investigation on the subjects’ professional development for their pedagogical competence in teaching implementation. The criteria of subjects selection have reflected the four competences that professional teachers need to possess which include personal, social, pedagogical and professional competences. The data collection was done by using questionnaire, interview guide, observation sheet. This study involves four selected professional English as a Foreign Language (EFL) teachers from Malang city, Malang Regency, and Batu town. The results show that PD activities done by the subjects include having discussion with colleagues, joining teacher association forum, attending seminars and workshops, taking courses, doing research, reading relevant sources, surfing the net,and doing team teaching. The ways how the subjects learn cover doing reflection, taking and giving feedback, discussing, broadening knowledge, researching, and problem solving. Referring to the limitation of this study, future researchers are recommended to do further study involving other aspects of pedagogical competence development, particularly the ones dealing with teaching preparation and evaluation on students learning.
