Which component is best described as sharing best practices and resources among teachers in a collaborative group?

• A. Modeling
• B. Communities of practice
• C. Ongoing coaching
• D. Measurable outcomes

Answer: (B)

Sharing best practices and resources among teachers in a collaborative group is a hallmark of communities of practice. This idea centers on groups of professionals who come together around a common interest or goal, engage with each other regularly, and develop a shared repertoire—things like lesson ideas, strategies, language, and tools—through ongoing dialogue and joint problem solving. Learning happens through participation, reflection, and mutual support, so the group grows as members contribute, critique, adapt, and spread effective practices.

Modeling is about one person showing how to do something for learners, not about peers sharing and building knowledge together. Ongoing coaching tends to be focused on guiding a specific individual rather than a collaborative group. Measurable outcomes refer to data and results used to assess progress, rather than the social process of developing shared practices within a group.
