Abstract
This study examines the impact of a professional learning (PL) project on secondary mathematics teachers' professional growth in their knowledge, beliefs, and instructional practices. Initially attributing teaching challenges to external constraints, some teachers gradually recognised the need for pedagogical development through reflection and researcher-guided discussions. The study highlights the dual role of challenges as both constraints and affordances, shaping engagement through structured support and positive student relationships. The findings reveal that teachers' perceptions of outcomes significantly influence their sustained involvement in professional learning.
