Building Pedagogical Content Knowledge within Professional Learning Communities: An approach to counteracting regional education inequality

Pedagogical Content Knowledge (PCK) and Professional Learning Community (PLC) are key notions to help understand teacher development for the benefit of student learning. Less understood is the contribution of PLC to PCK. This paper considers the Teaching and Research System in China to be a nationally institutionalised PLC for in-service teacher education. Building on quantitative analysis of a sample of 10,202 teachers, the paper concludes that participation in teaching and research activities within PLCs benefits teachers' PCK. The paper also concludes that building PCK through the Teaching and Research System has potential to counteract regional education inequality.
