Numbers in social practices: the case of Tseltal Mayan children / Los números en las prácticas sociales: el caso de los niños y niñas mayas tseltales

Abstract

From a historical and cultural perspective as well as a critical ethnographic approach, this work analyses the numerical relationships that take place within the social practices of the Tseltal Mayan community. In this social group, children learn to identify numbers through the use of cultural artefacts and natural elements, as well as collaborating with adults and other children, bringing body, emotions and cognition into play. We describe how for Tseltal Mayan children, numbers constitute a way of naming the world.     

Time for temporal team mental models: Expanding beyond “what” and “how” to incorporate “when”

Although often ignored, establishing and maintaining congruence in team members’ temporal perceptions are consequential tasks that deserve research attention. Integrating research on team cognition and temporality, this study operationalized the notion of a temporal team mental model (TMM) at two points in time using two measurement methods. Ninety eight three-person teams participated in a computerized team simulation designed to mimic emergency crisis management situations in a distributed team environment. The results showed that temporal TMMs measured via concept maps and pairwise ratings each positively contributed uniquely to team performance beyond traditionally measured taskwork and teamwork content domains. In addition, temporal TMMs assessed later in teams’ development exerted stronger effects on team performance than those assessed earlier. The results provide support for the continued examination of temporal TMM similarity in future research.
