Abstract
This study documents a school-based professional development activity
conducted in a secondary school in the Philippines where five secondary
mathematics teachers and the head of school participated in a program of
action research. Qualitative research techniques were used to provide rich
information on the changes made in teachers' pedagogical knowledge,
practices and beliefs. Within the parameters of certain constraints, it emerged
that action research as a form of professional development led to important
changes.
