Procesos de medición en una práctica artesanal del caribe colombiano. Un estudio desde la etnomatemática

Abstract

In this research it was identified that little attention is being paid to the ways of measuring, counting, among other activities that cultural groups do in their artisan practices, especially in processes related to gastronomy, which could contribute to the teaching and learning of measurement or metric systems. For this reason, this article characterizes the mathematical aspects involved in the measurement processes of a cassava bun merchant residing in Sibarco, Colombia. Theoretically, the work was based on the Ethnomathematics program and on the meanings of measuring, measurement, unit of measurement and bun. The methodology used was of a qualitative-ethnographic type. To collect the information, the semi-structured interview was used, audios were recorded, field notes were taken and video was recorded. The results show that the cassava bun dealer performs measurement processes using unconventional and conventional units of measurement such as breaststroke, load, bulk, lao, tercio, bucket, tank, and liter, pound, ounce, hours. Likewise, equivalences were identified between measurement units in practice. The results are considered to contribute to the teaching and learning of mathematics, since the reported units of measurement are a material that would allow mathematics teachers to create contextualized situations that link the student with his or her close sociocultural environment.
