Culture can be thought of a set of shared practices, beliefs, and values that are transmitted across generations through language [Bruner, J. (1990). "Acts of meaning". Cambridge, MA: Harvard University Press]. Teaching is one way that culture is transmitted, but forms of teaching vary across cultures and across activity settings within cultures. This article explores the impact of culture on styles of teaching in a place where more than one cultural model of teaching is found: the Zinacantec Maya of Chiapas, Mexico. Zinacantecs have an indigenous model of teaching that applies to the learning of informal tasks, such as making tortillas and weaving. When children go to school, the indigenous model interacts with the model found at school, and this mixed model is transferred back home to sibling interactions. Videotaped ethnographic observations and quantitative discourse analyses reveal cultural patterns in the development of children's teaching.
