Exploring Ethnomathematics in the Activities of Traders at the Niki-Niki Traditional Market

Yeni Misa — 2024-06-25

Mathematics is a form of culture inherent in all aspects of society's life. In the cultural practices of certain communities, mathematical concepts are involved. There is an intersection between culture and mathematics. Therefore, this research is conducted to explore the mathematical concepts used by traders. This study was conducted at the Niki-Niki Traditional Market. The research subjects consist of 6 individuals, with 2 betel nut sellers, 2 chili pepper sellers, and 2 woven fabric sellers. The data in this study are primary data collected through observation, interviews, and documentation techniques. Data analysis employs the techniques of ethnographic research data analysis, including domain analysis, taxonomic analysis, componential analysis, and cultural theme analysis. The results of the research indicate that there are mathematical concepts of plane geometry and integers in the activities of traders. Concepts of plane geometry include points, rectangles, circles, rhombuses, straight lines, curved lines, and fractal geometry. Meanwhile, mathematical concepts related to integers include sets, counting, addition, subtraction, division, and multiplication.

Predictive Analysis: Academic Resilience as a Determinant of Mathematics Achievement among Senior Secondary School Students in Nigeria

Mathematics is considered a key foundation for scientific knowledge required for the development of any nation. Poor mathematics achievement has been reported nationally. This paper was designed to investigate academic resilience as a determinant of mathematics achievement among senior secondary school students in Owerri municipal council of Imo State. A correlational design was used for the study. The study comprised a population of 32,068 students in public secondary schools in Owerri Municipal Council of Imo State. A sample of 180 SSII students was drawn from the population, using simple random sampling. Two instruments were used for data collection in this study. They are: the Academic Resilience Scale (ARS) for secondary school students was developed by Martin and Marsh with a Cronbach reliability coefficient of 0.74, and the Mathematics Achievement Proforma (MAP). Descriptive and inferential statistics including simple linear regressions were used for data analysis. The findings showed that academic resilience positively and significantly predicted mathematics achievement irrespective of gender. It was recommended to prepare and encourage students to be resilient, with the spirit of resilience inculcated at a young age, as this helps them in life and positively predicts mathematics achievement.

An Analysis of Ethnomathematics Didactical Contract in the Sums of Interior and Exterior Angles

Clement Ayarebilla Ali — 2024-06-25

Teachers and students have different ideas and expectations about the didactical situation that evolves in the classroom. It needs rules that determine teachers’ and students’ unique responsibilities relating to the didactical situation or contract. The division of roles and responsibilities moves from the teacher as the centre to the students as the centre. The results of a case study design of 42 students showed that the transition from ostentation to Mayeutic Socrate and then to the adidactical contracts was smooth and progressive if the teacher and the participants cooperated and actively participated in the milieu. It was therefore recommended that teachers streamline method-friendly guidelines, strategies, and techniques at the ostentation contract for students to emulate, students cooperate and support the teacher at the mayeutic Socratic contract and the knowledge of both local indigenous and exotic artifacts must complement each other at the adidactical contract.

Utilization of Instructional Materials and Junior Secondary Students’ Academic Achievement in Geometrical-Shapes

This study investigates the utilization of instructional materials and junior secondary students’ academic achievement in geometrical shapes. A quasi-experimental design with experimental and control groups, including pre-test, post-test, and post-posttest measures, was implemented. The target population consisted of 1329 JSS II Students from Bida Local Government Area, Niger State, with sample size of 171 (Male=84, Female=87) students from two schools and two intact classes. Sample was determined through purposive and simple random sampling, selecting all mixed schools with experimental and control groups. Three research questions and hypotheses were formulated to guide the study. Data collected employed instruments: The Geometry Performance Test (GPT), Geometry Achievement Test (GAT), Lesson model for the control and experimental group. The GPT and GAT were validated by three experts and also demonstrated good reliability. The results revealed that students taught with instructional material performed better comparing with those taught without instructional materials and also there is no significant differences found in gender in the experiment group. In addition, there is significant difference in the retention ability of those who were taught using instructional materials and those taught without instructional material. Based on these results, mathematics teachers should use instructional materials during teach mathematics especially geometrical shapes.

Mathematical Concepts and Cultural Values in Sonaf Tamkesi: Ethnomathematics Study in a Traditional Village on Timor Island

Fedelia Funan — 2024-07-31

Mathematics is a universal science, and it is crucial for everyone to master it, both in terms of its applications and its cognitive patterns. The purpose of this research is to explore the concepts of mathematics and cultural values found in the artifacts of Sonaf Tamkesi Manufui. The study was conducted in the traditional village of Tamkesi, south Biboki District, North Central Timor Regency, in July 2023. The subjects of this study were three community leaders. The type of data collected for this research was primary data obtained through documentation and interviews between the researcher and the respondents. Data analysis was conducted through stages of domain analysis, taxonomy, componential analysis, and cultural themes. The research findings indicate that there are concepts of plane geometry in the artifacts such as trapeziums, rectangles, squares, rhombuses, triangles, circles, cylinders, hexagons, and cubes. Meanwhile, the cultural values of the artifacts in Sonaf Tamkesi are the roof symbolizes harmony, the door symbolizes greatness and respect for ancestors, the pillars symbolize vertical relations with ancestors, the betel-nut container symbolizes service, the clay pot symbolizes a gift from ancestors to the living, the hearth symbolizes balance, and harmony in achieving goals.
