Abstract

The ability of mathematical representation is very important to solve mathematical problems, because every solution must use mathematical representation. This research was conducted at Thailand's Streesmutprakan School because according to the results of the 2015 PISA test, mathematical representation skills also affected the execution of the PISA test. The PISA test results in 2015 showed that the Mathematics ability of Thai students was ranked 54th out of 70 countries with an average score of 415. While the average score for Mathematics from all countries taking the PISA test was 490. The results showed that Thailand was still in in a position below the average. The method used in this research is descriptive qualitative, by giving PISA questions about shape and space content. The results of this study indicate that students with high abilities are superior in visual mathematical representation. This can be seen from the number of cube nets that can be drawn with different models. The indicator of mathematical expression is only one of six students who can meet the indicator and answer correctly. For indicators of the ability to represent in words or written texts, students with high abilities are also more prominent because they have a reason for each answer, whereas for students with medium and low abilities only guess even silence during interviews.

Abstract

A culture is born from the local community so as to produce works that become the characteristic of the culture. This culture is rooted and develops over time. One result of cultural work is Banyuwangi solok weaving. Education appreciates local culture in order to participate in preserving through the teaching and learning process. Weaving Solok Banyuwangi can be included as a medium for student learning in schools. Mathematics is one branch of science that studies symbols with logical reasoning. So there are estimates of the mathematical elements found in the Banyuwangi solok weaving motif. Mathematical elements found in Banyuwangi solok weaving include points, lines, triangles, quadrilaterals, hexagon, folding symmetry, rotary symmetry, congruence and similarity.

Abstract

The purpose of this study is to explore ethnomatematics in the activities of cocoa farmers to create the teaching materials for students in the form of the packages of test. The type of research was qualitative research with ethnographic approaches. The data collection method used were observation and interview. The research subjects were six people. The ethnomatematics included the activity of counting, measuring, and designing. This study focused on determining the estimated number of trees based on its distance and area by using stakes (patok), determining the fertilization model based on the fertilization time and the planting age, determining the number of workers based on the land area, and estimating yields. The emerging mathematical concepts were comparison and social arithmetic.

Abstract

The purpose of this study is to describe the profile of algebraic thinking in junior high school students in solving mathematical problems in terms of cognitive style (reflective and impulsive). The subjects used were class VIII B Arjasa 1 Junior High School as many as 25 children. Data collection in this study used two test questions, namely the MFFT test (Matching Familiar Figure Test), algebra test and interviews with four students representing different cognitive styles (reflective and impulsive) . In this study students who have reflective cognitive style and students who have impulsive cognitive style can fulfill five indicators of algebraic thinking, namely generalization, abstraction, analytical thinking, dynamic thinking, and modeling.

Abstract

Ethnomatematics is the practice or daily activities of a society that has become a culture and there is the application of basic mathematical concepts. The purpose of this research is to describe ethnomatematics on the activities of hatching process of semi-natural green turtle eggs in Sukamade, Meru Betiri National Park to make teaching materials for students in the form of test questions and calculate the fractal dimensions on sand used for hatching the eggs of green turtle. This type of research is qualitative research with an ethnographic approach. The data collection methods used are observation and interviews. The research subjects were the UPKP (Turtle Conservation Management Unit), MMP (Gamekeeper Partner Community) and Facilitators. This study focuses on the activities to calculate, measure, and design. The mathematical concepts that arise are arithmetic operations, value comparisons, arithmetic series and geometric shapes. Fractal dimension calculations on natural and semi-natural sand in the process of hatching green turtle eggs with MATLAB aid program obtained the fractal dimensions on natural sand was 1.7252 and on semi-natural sand was 1.7273.
