In an era where student-centered instruction and competency-based learning are gaining traction globally, enhancing teacher capacity remains a pivotal challenge. Recognizing this, a team of Chinese education researchers has turned to framing theory to better understand how collaborative professional development models—particularly lesson study—can drive meaningful shifts in teachers’ instructional practice.

Effective teacher noticing supports teacher learning by enabling reflection of what was noticed, or missed, during teaching. A new study examined two primary school mathematics teachers from China to understand their professional noticing in everyday classroom contexts. The researchers investigated what teachers noticed about students' mathematics learning and how this noticing translated into instructional decisions.
