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.
