Analysis of the ethnomathematical connections in the elaboration and commercialization of Chinese rice in the south of the department of Atlántico, Colombia

Abstract

The ethnomathematical connections in the elaboration of Chinese rice in the municipality of Suan, Atlántico, were analyzed. The research is qualitative and was developed in three stages where a Chinese cook and rice maker was selected. Subsequently, semi-structured interviews were conducted with the participant to collect the information and, finally, the data was analyzed based on the conceptual framework. The results evidenced the mathematics used by the Chinese rice cook when carrying out measurement processes using unconventional and conventional measurement units such as cup, handful, ladle, liter, pound, quarter, half, hour and equivalences between units of measures. In addition, ethnomathematical connections were recognized, relating the cup with the contents of the curriculum and in marketing, measures such as the spoon, the plate and the box are used. These findings are useful for creating tasks to link mathematics with its sociocultural environment.
