Abstract

This study aims to determine the characteristics of students’ metacognition process at the level of informal deduction thinking in solving geometry problems. This research is a qualitative descriptive research. 66 elementary students were tested about their thinking ability of Van Hiele geometry by dividing them into some groups according to their geometry thinking level. The informal deductive thinking level group was tested for problem-solving geometry. Furthermore, interviews were conducted to explore the characteristics of their metacognition process. Based on the data analysis, the characteristics sequence of the metacognition process is complete through the process of planning, monitoring, and evaluation. The metacognition process indicator appears in each problem-solving component, from understanding the problem, preparing a problem-solving plan, implementing a problem-solving plan to check the solutions obtained.

Abstract

Students with a rigor level of geometric thinking can analytically solve problems, yet the ability may not be readily observable. Thus, an example of how students solve problems merits explorations. Inspired by student’s problem solving, this study aimed to examine the student’s anticipatory profile in determining Papaya tree roots' dimensions. This qualitative research utilized tests and interview. Two tests were carried out: van Hiele geometric level grouping test for selecting the research participants and the report-based test for the actual project. Seventeen students took the van Hiele test, and one of them, who achieved the rigor level, was selected for the interview. Data obtained from the interview were then analyzed qualitatively. The study showed that students with a rigor level of geometric thinking anticipated analytically. The subject was able to explain a geometric problem systematically, starting from analyzing problems, clarifying detailss, to presenting arguments clearly and precisely. The findings in this study generate useful information for teachers who train their students to analyze a geometric problem correctly and adequately.

Abstract

This research examined both the students’ understanding of mathematical problems and their difficulties in solving the problems based on the SOLO taxonomy. The Collis-Romberg test of mathematical problem solving consisting of five items, each having four questions, was administered to 582 first-year students from 15 classes of public senior high schools in Jember. The results indicated that 8.82%, 7.73%, 33.30%, 34.67%, and 16.01% of the students were respectively at prestructural, unistructural, multistructural, relational, and extended abstract levels. The students’ difficulties were identified as follows: they did not understand the stems; they did not understand the questions; and they did not understand the concepts of digit and number, double proportion, and locus of points.

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

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

Tujuan penelitan ini adalah untuk menggali etnomatematika pada bangunan Masjid Jami’ Al-Baitul Amien Jember yang kemudian digunakan sebagai bahan untuk membuat paket tes matematika bagi siswa. Penelitian ini merupakan penelitian kualitatif dengan pendekatan etnografi. Metode pengumpulan data yang digunakan adalah observasi dan wawancara. Subjek penelitian yaitu tiga observer dan dua narasumber yakni pengurus Yayasan Masjid Jami’ Al-Baitul Amien Jember.  Satu orang merupakan ketua pengurus yang paham tentang sejarah Masjid Jami’ Al-Baitul Amien dan satu orang merupakan satu-satunya pengurus yang mengikuti masa pembangunan sehingga mengerti terhadap struktur bangunan masjid. Hasil penelitian menunjukkan bahwa pada bagian-bagian  bangunan Masjid Jami’ Al-Baitul Amien Jember terdapat konsep-konsep matematika. Bagian-bagian bangunan yang dimaksud yaitu kubah masjid, tiang penyangga masjid, lantai dua, dinding pancuran Ruang Wudlu, dan menara masjid. Konsep-konsep matematika yang muncul adalah bangun datar, bangun ruang, kekongruenan, dan refleksi.Ethnomathematics exploration at the Jami 'Al-Baitul Amien Jember MosqueAbstractThe purpose of this research is to explore ethnomathematics at the Jami 'Al-Baitul Amien Jember Mosque building which is then used as material to design mathematics test packages for students. This research was a qualitative study with an ethnographic approach. The data collection methods used were observations and interviews. The research subjects were three observers and two resource persons, namely the management of the Jami 'Al-Baitul Amien Jember Mosque Foundation. One person is the chairman of the committee who understands the history of the Jami 'Al-Baitul Amien Mosque and one person is the only administrator who followed the construction period so that he understands the structure of the mosque building. The results show that the parts of the Jami 'Al-Baitul Amien Jember Mosque have mathematical concepts. The building parts meant are the dome of the mosque, the pillars of the mosque, the second floor, the shower wall of the Wudlu Room, and the mosque tower. Mathematical concepts that emerge are 2D shapes, 3D shapes, congruence, and reflection.

Abstract

Abstract. Ethnomathics is a multicultural mathematics activity that uses culture to make connections with distinctive mathematical topics, so as to motivate students to investigate and preserve their own culture while learning mathematics. The purpose of this research is to explore the ethnomatematics contained in Gajah Oling batik based on the concept of geometry and to produce teaching material products in the form of student project sheets. This type of research is qualitative with an ethnographic approach. The data collection methods used were observation and interviews. The research subjects were 1 person, namely a designer and an isen-isen batik maker from Gajah Oling. Ethnomatematics appears both in the results of batik and in the process of making designs and isen-isen. At the isen-isen stage, the concept of points and lines appears, while at the stage of making Gajah Oling's batik designs, the concepts of angles, flat shapes, congruence and congruence, geometric transformations which include translation, rotation, reflection, and dilation appear.Keywords: Ethnomatematic, Gajah Oling’s Batik, Geometry, Geometry Transformation
