Abstract

In general, the North Wewewa Wewewa Woven Fabric of Bokuna Village is passed down from the ancestors and followed until now this Woven Fabric has beautiful motifs made based on daily life and also from nature. Ethnomathematics is a bridge between culture and mathematics, ethmomathematics is adapted by cultural groups to see that the culture contains mathematical aspects. This research aims to find out the concept of geometry in Woven Fabrics. The data collected is in the form of documentation, interviews, and observation results. The type of research used in qualitative descriptive is to describe the mathematical elements contained in woven fabrics. Data collection uses observation and interviews. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the analysis show that Woven Fabrics are sacred crafts that are inherited from ancestors or from generation to generation. In the study, the researcher found several one-dimensional and two-dimensional buildings. The geometric shapes found by the researcher are: rectangular shape on the entire shape of the woven fabric, an equilateral triangle shape on the mamuli motif, an isosceles triangle shape on the flower motif, a bele ketupat shape on the star motif, a rectangular shape on the entire woven fabric, a square shape on the butterfly motif

Abstract

This study aims to find out the difficulties of students in solving PLSV problems using the demonstration method for grade VII students of SMP Negeri 5 Lamboya. This study uses a qualitative approach with a descriptive method. 14 students as subjects to be researched to the extent to which the students can work on one-variable lienar equation problems. The data collection methods used are tests, interviews, and documentation. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the study showed that there was still a lack of ability of students to solve PLSV questions that answered the questions correctly and incorrectly. The results of the analysis for problems number 1, 2 and 3 were at the stage of difficulty in interpreting mathematical language (59.66%), the stage of difficulty in using data (64.33%), the stage of difficulty in mastering concepts correctly (66.66%), the stage of difficulty in using calculation operations (66.66%), and the stage of difficulty in drawing conclusions (83.33%). The cause of incompetence is that students do not read the questions carefully so that they make mistakes in writing down what is known and what is asked, so that they are less able to solve problems, in a hurry so that others are incomplete.

Abstract

This study aims to determine student errors clearly VII SMPK St. Paul Karuni in solving HOTS-type math problems on set material. This type of research is descriptive with a qualitative approarch. Data analysis techniques use steps consisting of 3 steps, namely: data reduction, data presentation, and drawing conclusions. Based on the results of the study, it can be concluded that the types of errors that arise when students solve the set material story problem are 1) errors in understanding the problem, where students do not complete writing down what is known in the question and does not write down what is known and what is asked in the question. 2) transformation error, where students cannot change the problem from story form to mathematical form and do not complete the solution. 3) Process skill errors, where students are unable to perform calculations. 4) Errors in writing the final answer, where students write the final answer that does not match in the question.Factors in students that cause student errors are not having the ability to write down things that are known and asked in the problem, rushing to solve the problem, not having the ability to do the correct solution, and not understanding the calculations used.

Abstract

The purpose of this research is to find out the ethnomathematics in the traditional house of Tago'o Village, North Wewewa District and its introduction in learning at SMA Negeri 1 North Wewewa. This research adopted qualitative and exploratory methods with research subjects consisting of traditional leaders, hosts, and traditional house builders in Tago'o Village. The results revealed several findings related to traditional houses in Tago'o Village, such as the trapezium on the front view of the traditional house tower, the triangular shape seen from the side, and the concept of intersecting lines called karaga umma. The structure of the traditional house shows the use of wood that forms horizontal and intersecting lines, with the pillars of the traditional house forming vertical and perpendicular lines. In addition, the study also identified various geometric shapes such as blocks, rectangles, squares, circles, tubes, spheres and acute angles found in various parts of the traditional house, from the inside such as food storage to the outside such as under the house for pets. These findings provide an overview of the use of mathematical concepts related to the design and structure of the traditional houses of Tago'o Village. The implication is that this knowledge can be applied in the context of learning at SMA Negeri 1 Wewewa Utara to enrich students' understanding of mathematics in everyday life based on local wisdom.

Abstract

This article examines the level of students' numeracy literacy skills. The reference in testing students' numeracy literacy skills in this study used math questions in the PISA program for students aged 15 years. The ranking of Indonesian students' mathematical literacy from 2009 to 2015 did not show a significant increase. In 2009 Indonesia was ranked 68th out of 74 countries. In 2012 Indonesia ranked 64th out of 65 countries with a relatively low level of achievement. While the results of PISA in 2015 showed that Indonesia's ranking experienced a slight increase, namely 63rd out of 72 countries. The purpose of writing this article is to find out how far the students' numeracy literacy skills are at SMP Negeri 3 Tambolaka City. The method used is a type of sequential explanatory research and a mixed method research approach.

Abstract

The purpose of this research is to determine the mathematical reasoning abilities of students in solving problems on the topic of Systems Of Linear Equations In Two Variables at SMP Negeri 6 Kodi. The type of this research is qualitative research. The subjects of this research are all the students of class VIII B at SMP Negeri 6 Kodi, totaling 29 students. The interview subjects were three students from each category, namely the high, medium, and low categories. The object of this research is for the researcher to understand the mathematical reasoning abilities of the students. The data collection techniques used are written tests, interviews, and documentation. Based on the reserch results, the mathematical reasoning ability on the topic of systems of two variable linear equations (SPLDV) for students in class VIII B SMP Negeri 6 Kodi shows variation in meeting the reasoning indicators. Students with high mathematical reasoning ability are able to meet for mathematical reasoning indicators in solving SPLDV problems. Students with moderate mathematical reasoning ability can meet three indicators, while students with low mathematical reasoning ability can only meet one reasoning indicator in solving SPLDV problems. So, the researcher can conclude that the mathematical reasoning ability of the eighth-grade students of SMP Negeri 6 Kodi is still very low
