This presentation examines how a Critical Commentator (CC, the author) facilitated reflection amongst seven Singapore primary mathematics teachers during a school-based professional development programme. Laboratory class cycle involving planning, observing and critiquing mathematics lessons was used as a framework for the programme. With the aid of a questioning framework, the CC was able to help these teachers improve the quality of their reflections, moving from Level 1 technical reflection, to the Level 3 critical reflection. The difficulties in recalling exact details of the observed lesson which prompted the teachers to embrace video technology for their reflection were also examined.
