Title: “Unraveling Ethnomathematics in Panaeaba (Oyster Farming)”

About the Research

This focused ethnographic study of qualitative research paved the way for unraveling Ethnomathematics in Panaeaba. I used ethnomathematical analysis to unravel the Ethnomathematics and document analysis to identify the mathematical concepts and principles vis-à-vis K-12 competencies used by the fourteen (14) Manugtaeaba who were chosen purposively. This study was generally governed by the epistemological umbrella of constructionism and symbolic interactionism as its interpretive approach for the thematic, ethnomathematical and document analyses. Results show that ethnomathematics along Numbers and Number Sense, Algebra, Measurement, Geometry, Business Mathematics and Logic were unraveled in Panaeaba. The EKPS on numbers and number sense used by Manugtaeaba were rational numbers, paghuyap, pareho, indi’t pareho, bana-bana, pagdugang, pagbuhin, pagpaabo, pagpartida, ratio and proportion. For EKPS along Algebra includes the parabola, relations and functions in line with size or area of oyster shell, tubo, eotaw, karga, agad’s/tuhog’s length and quantity, minimum function, navigational speed, gataw, and tidal activity. Out of the results on the unraveled EKPS in Panaeaba, I came up with the matrix of the mathematical concepts and principles patterned from EKPS and K-12 learning competencies known as TALAMATH. From this matrix, I developed TALAMATH lesson exemplar that can be used in the teaching and learning process of mathematics a well as guide for potential development of instructional materials contextualized in oyster farming.

About the Researcher

The researcher is a faculty of Senior High of Capiz National High School at Roxas City, Capiz. He wants to promote mathematics contextualization that is why he ventures Ethnomathematics research believing that this is an avenue to connect mathematics to the life’s space (culture) of the learners. His study becomes a reality because being a Capizeño but by dialect an Akeanon he wants to prove that indeed Capiz is the seafood capital of the Philippines aside from being grateful to what he has achieved today, that he was once a Manugtaeaba (Oyster Farmer) and now becoming a PhD holder.
