    Abstract : In the last decade, Professional Learning Communities (PLCs) are increasingly used as models for teachers’ joint efforts in developing their teaching. The overall aim of this licentiate thesis is to expand the knowledge of PLCs in mathematics, by deepening the understanding of aspects that influence the establishment, organization, and implementation of PLCs in mathematics.
