Tasikmalaya is a Sundanese region whose nickname is: "The Pearl of East Priangan", an important role in South West Java Province. This role is very influential on the potential of the community, including in the field of culture. But along with the times, this culture is less well known by today's young generation. The purpose of this research is for the culture of the Sundanese people, especially in Tasikmalaya so that the culture is maintained. This study uses a qualitative approach with an ethnographic approach derived from literature studies, field observations and interviews with a Sundanese cultural expert. The results of the study indicate that there is a mathematical language in the right time of day and night that is used by the Sundanese people in Tasikmalaya and it can be a starting point to be used as a reference in learning mathematics.
Penelitian ini bertujuan untuk menggambarkan pencapaian dan peningkatan kemampuan berpikir kreatif matematik (KBKM) dan kemandirian belajar peserta didik melalui implementasi Pendekatan Matematika Realistik (PMR). Populasi penelitian ini adalah peserta didik SMP Negeri di Kota Tasikmalaya. Sampel penelitian adalah peserta didik kelas VIII yang mewakili satu sekolah level tinggi dan satu sekolah level sedang. Penelitian ini merupakan penelitian kuasi eksperimen dengan desain kelompok kontrol pretes-postes. Instrumen yang digunakan yaitu tes KBKM, skala kemandirian belajar peserta didik, dan lembar observasi. Analisis data menggunakan uji Kruskal Wallis. Dari hasil penelitian disimpulkan: 1) Pencapaian dan peningkatan KBKM kelompok PMR lebih baik dari kelompok PK; dan 2) Pencapaian dan peningkatan kemandirian belajar kelompok PMR lebih baik dari kelompok PK.The purposes of this study are to describe the enhancement and the achievement of students’ Mathematical Creative Thinking Skills (MCTS) and Self Regulated Learning (SRL) through implementation of Realistic Mathematics Education (RME) and Conventional Learning (CL). The population of this study were Junior High School students in Tasikmalaya City. The sample of this study were eighth grade students representing the high school level and the medium school level. This research is a quasi-experimental design with pretest-posttest control group. The instrument used is a test MCTS, scale independence of learners, and the observation sheet. Analysis of data using Kruskal Wallis test. The final conclusion: 1) Achievement and improvement of MCTS RME group is better than CL group; and 2) Achievement and improvement of Self Regulated Learning (SRL) RME group is better than CL group.
AbstrakPenelitian dilakukan mengingat pentingnya memperhatikan kemampuan berpikir kritis dan tipe kepribadian untuk menunjang keberhasilan belajar matematika. Penelitian ini mendeskripsikan proses berpikir kritis matematis siswa ditinjau dari tipe kepribadian ekstrovert dan introvert. Metode penelitian yaitu kualitatif eksploratif, dengan subjek sebanyak empat siswa kelas XII teknik busana butik salah satu SMK Negeri di Rajadesa. Instrumen yang digunakan yaitu tes kemampuan berpikir kritis matematis, wawancara, dan angket tipe kepribadian. Hasil penelitian menunjukkan bahwa subjek ekstrovert lebih cepat dibandingkan dengan introvert dalam menyelesaikan masalah, tetapi kurang teliti dalam menyelidiki permasalahan. Subjek ekstrovert juga menggunakan konsep yang salah ketika menarik kesimpulan, mereka tidak tepat dalam mengaitkan informasi yang ada dengan pengetahuan yang dimilikinya. Sedangkan subjek introvert, cenderung tenang, teliti, hati-hati, dan memikirkan kembali solusi sebelum menarik kesimpulan. Siswa introvert mampu mengembangkan argumen dengan mengembangkan informasi yang ada dan memberikan pernyataan yang mengarah pada langkah-langkah yang diambil dalam menyelesaikan masalah, meskipun tidak dapat menuliskannya dengan tepat. Students' Mathematical Critical Thinking Process Judging from Extrovert and Introvert Personality TypesAbstractThe research was conducted considering the importance of paying attention to critical thinking skills and personality types to support the success of learning mathematics. This study describes students' mathematical critical thinking processes in terms of extrovert and introvert personality types. The research method is qualitative exploratory, with the subject as many as four students of class XII fashion boutique engineering one of the SMK in Rajadesa. The instruments used are mathematical critical thinking ability tests, interviews, and personality type questionnaires. The results showed that extroverted subjects were faster than introverts in solving problems but less thorough in investigating problems. Extroverted subjects also use the wrong concept when concluding, they are not right in relating the existing information to the knowledge they have. While introverted subjects tend to be calm, thorough, careful, and rethink solutions before concluding. Introverted students can develop arguments by developing existing information and providing statements that lead to the steps taken in solving problems, even though they cannot write them down correctly.
This research aimed to analyze and explore the capability of mathematical proficiency second semester math education students of Faculty of Teacher Training and Education (FKIP) Khairun University academic year 2017/2018. In this study mathematical problems are presented in Calculus, and given the opportunity for students to understand the problems provided both from the theoretical aspects related to indicators of mathematical proficiency namely conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition, which further uses Interactive Maple Tutor, Maple Assistant, and Show Solution commands. Students in this study can take some steps themselves, and ask Maple to take the next step. Research data were collected and analysed with a descriptive-qualitative approach of student work for each indicator of mathematical proficiency with research subject in total 128 students. The results showed that the ability of the mathematical proficiency of students of mathematics education in the medium category.
Matematika merupakan ilmu tentang pola, struktur dan bentuk yang terintegrasi dalam budaya masyarakat. Konsep-konsep matematika yang diaplikasikan, merujuk pada aktivitas, kebiasaan, ataupun adat kehidupan masyarakat dalam menyelesaikan masalah disebut etnomatematika. Salah satu aplikasi etnomatematika ini terdapat pada Candi Borobudur. Candi Borobudur adalah megastruktur konseptual matematika yang dibangun sejak berabad-abad tahun yang lalu, dimana pada masa itu belum berkembang teknologi modern. Penelitian ini bertujuan untuk membahas tentang ajaran, filosofi, dan konsep matematika yang terdapat dalam Candi Borobudur, serta hubungan dari ketiganya. Penelitian ini menggunakan metode eksploratif dengan pendekatan historis dan kultural. Simpulan penelitian ini adalah sebagai berikut: (1) Candi borobudur sebagai produk etnomatematika menyajikan berbagai konsep agama, moral, budaya, dan matematika, (2) Secara keseluruhan, konsep-konsep tersebut memiliki hubungan dan keterkaitan diantara satu sama lain, (3) Konsep-konsep yang disepakati dan diterapkan dalam realita kehidupan, telah membawa matematika sebagai produk budaya yang tertanam sejak zaman dahulu meskipun mereka tidak menyadarinya, dan (4) Candi borobudur merupakan contoh monumen dari orkesta matematika dalam bentuk etnomatematika.Math is the science about the patterns, structures, and shape, integrated into the culture of the life of the community. Mathematical concepts which applicated in the cultural community, refer to activities or customs, habits, life incomplete the problem is called ethnomathematics. One of these ethnomathematics application is present on the Borobudur Temple. Borobudur Temple is a conceptual mathematical megastructure that was built centuries years ago, which at the time was not yet developing modern technology. The purpose of this study is to discuss the form of teaching, philosophy and mathematical patterns of the structure of the building of the temple, as well as the relationship of the third focus of the study. This research method using exploratory with historical and cultural approaches. The conclusions of this research are as follows: (1) Borobudur temple as ethnomatematics product presents various religious, moral, cultural, and mathematical concepts, (2) Overall, these concepts have a relationship and interrelationships with each other, (3) Concepts which are agreed upon and applied in the reality of life, have brought mathematics as a cultural product that has been embedded since ancient times even though they were not aware of it, and (4) Borobudur temple is an example of a monument of a mathematical orchestra in the form of ethnomatatics.
