Abstract:

The major focus of this study was to create a DIY projector called “MATHSTAX” that would enhance and strengthen the Ethnomathematics of the Badjao tribe located in Brgy. Malitam, Batangas City. Specifically, the researchers determined the current Ethnomathematics of the tribe by immersing themselves in the community. Through this immersion, the researchers learned about the tribe’s rich culture and history and discovered how this tribe uses Mathematics in their everyday lives. The Badjaos showed that they are mathematically competent based on Niss’s (2001) mathematical competency structure. This study used purposive non-probability design. Research participants consisted of five key-informants from the approximately 467 families living in the Badjao community, and one core-group composed of six people. Through observation and interview, the data were gathered and analyzed. Findings showed that the Badjaos are proficient in counting numbers; however, members of the tribe were noted poor in measurement. The “MATHSTAX” was developed to address their math challenges. Consequently, this learning material could be used by the Badjao ethnic group to enhance their Ethnomathematics. Furthermore, this would help in the development of Badjao IPED curriculum.
