We outline this context and consider concepts of good teachers in classical Chinese traditions and more recent Western thinking as a possible dialogue within and between cultures of learning. Using cognitive and cultural linguistic perspectives, we analyze metaphorical concepts of "gold" in "the gold standard" as related to teachers. We report our applied metaphor research which analyzes Chinese students’ expectations, values and beliefs about good university language teachers;this presents a rich picture beyond developing knowledge, skills and understanding to include strong social and moral characteristics. Other aspects which recognize the complexity of "good" teachers show a student appreciation of teachers’ tireless effort, devotion and selfless sacrifice: these aspects are absent in many discussions of good teachers. The participant-centered picture from elicited metaphor analysis is part of students’ "cultures of learning," but this should be developed culturally for the gold standard through further teacher development and student engagement. In line with interaction in cultures of learning, we indicate some classroom ways to extend students’ thinking through scaffolding teacher-student interaction based on textbook activities.展开更多
