How to predict good days in farming: ethnomathematics study with an ethnomodelling approach

Mathematics cannot be separated from everyday life. The use of mathematical concepts in cultural activities can be studied through the ethnomathematics program. However, ethnomathematics research may not be able to provide noticeable results, especially in constructing mathematical modelling for pedagogical purposes. Ethnomodelling later became one of the concepts introduced as an approach in ethnomathematics research. Based on the cultural aspect, the ability to predict a good day in farming is included in the holistic concept of culture because it belongs to the knowledge system and belief system (religion) in the universal element of culture. The research was conducted using an ethnomethodological approach and a realist ethnographic design. Based on this, this research was conducted to describe the ability of the Cigugur indigenous people in Kuningan Regency to predict what days are considered good to start farming activities. Data were collected by using observation techniques, in-depth interviews, documentation, and field notes. Data analysis techniques are carried out in stages through content analysis, triangulation, and pattern search. Based on the study of ethnomathematics, research that is able to describe the mathematical ideas and practices of the indigenous Cigugur community can be classified into several fundamental mathematical dimensions including counting, finding, measuring, designing, and explaining. The use of the ethnomodelling approach in research can describe several mathematical concepts used by the concepts of numbers, sets, relations, congruence, modulo, and mathematical modelling.

Ethnomathematical study on folk dances: focusing on the choreography

The investigation in ethnomathematics we are developing aims to analyse the mathematical structure inherent in various elements that constitute folk dances of Northern Portugal and Galicia, which is an autonomous community of Spain, specifically choreography, music and accessories. Focusing on choreography, we intend to represent and describe the movements that dancers perform during dances. Different types of choreography were identified in folk dances based on dispositions that although dancers may not remain fixed through the dance, are those to which they end up returning. In addition, diagrams and numerical schemes were elaborated to represent the successive positions occupied by dancers or pairs through the folk dances. The mathematical ideas and procedures resulting from this ethnomathematical research will then be used for school practice, through the construction of tasks to be applied in the classroom.

Etnomatemáticas en Artesanías de Trenzado: aplicación de un modelo metodológico elaborado

In a previous article we showed the development of a methodological model or tool for research named MOMET (OLIVERAS; ALBANESE, 2012) constructed for the ethnographical and ethnomathematical study of braiding crafts. In the present work we will show how to apply this methodological tool to two paradigmatic examples of braids products of two different braiding crafts. The ethnographical work required an immersion in the field in each of the two craft scenarios. The interpretative analysis and the application of methodological tool have made possible a systematic ethnographical study of the mathematics involved in the process of braiding.

Mutual Interrogation: A Methodological Process in Ethnomathematical Research

This paper describes an adaptation of a methodology called mutual interrogation to an ethnomathematical study on Malay weaving. Mutual interrogation is the process of implementing a critical dialogue between two knowledge systems; mathematical knowledge and cultural knowledge. It is proposed as a way of resolving several common issues in investigations of mathematical knowledge in cultural practice. Using this approach, a three-phase dialogue between Malay food cover (tudung saji) weavers and mathematicians was implemented. The interactions between the conventions of the weavers and the conceptions of the mathematicians have uncovered several interesting perspectives that address critiques of ethnomathematical research.
