This chapter presents the narratives of Ms. Zhong, a Chinese mathematics specialist teacher whose practices emphasize strong mathematical foundations, structured lessons, and discipline-specific thinking. After observing a Canadian math lesson, she raised a central puzzle: “Can you achieve your teaching goals?” Her story, however, also shows transformation. She began experimenting with inquiry-based projects and came to value Canada’s support for special education. Through initiatives such as her “Little Mathematics Star” program and her involvement in collaborative professional networks, Ms. Zhong maintained her commitment to specialist teaching while becoming more open to new approaches. Her journey highlights both the strengths of specialist expertise and the potential for professional growth through cross-cultural reciprocal learning.
