An ethnomodel of squid trap “Bubo” in Gigantes Island, Western Visayas, Philippines

Abstract

This study investigated the mathematical model for squid traps (Bubo) as one fishing gear in Gigantes Island, Western Visayas, Philippines. Field notes, video recordings, interviews, and participant observations were conducted from constructing the squid trap (Bubo) to its application. A mutual interrogation approach was utilized as approach to ethnomodeling to present cultural practices of the “manugbubo” and the parallel and beyond of these practices in academic mathematics. The model of a squid trap (Bubo) displays symmetry, congruence, similarity, angles, transversal, triangles, and parallelograms. The angles formed within a squid trap can aid in understanding concepts such as sine, cosine, and tangent, as well as their applications in solving problems related to right triangles. Using this squid trap model in teaching mathematics will encourage teachers and learners to value the richness of mathematical knowledge and appreciate academic mathematics, knowing its presence in their daily activities in their community.
