Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan pendidikan matematika realistik terhadap hasil belajar peserta didik kelas XI dalam materi lingkaran di SMA Panca Setya Sintang. Metode penelitian yang digunakan dalam penelitian ini adalah eksperimen dengan rancangan penelitian one-shot case study. Populasi dalam penelitian ini adalah peserta didik kelas XI IPA SMA Panca Setya Sintang. Sementara sampel yang digunakan yaitu peserta didik kelas XI IPA 2 yang berjumlah 24 peserta didik. Teknik pengumpulan data hasil belajar menggunakan teknik pengukuran dengan mmberikan tes soal essay dalam materi lingkaran kepada peserta didik. Untuk melihat kekonsistenan dalam pencapaian hasil belajar, maka setelah dua minggu kemudian diberikan tes tunda. Besar rata-rata nilai pada saat tes akhir adalah 53,82, sedangkan rata-rata nilai pada saat tes tunda adalah 55,56. Berdasarkan perhitungan uji t tes rata-rata satu sampel diperoleh nilai  dan  dengan taraf signifikan  hal ini berarti  maka  diterima artinya tidak terdapat perbedaan yang signifikan antara rata-rata nilai peserta didik pada saat tes akhir dan tes tunda. Maka terjadi kekonsistenan antara nilai tes akhir dan nilai tes tunda, hal ini berarti penerapan pendekatan pendidikan matematika realistik pada materi lingkaran berpengaruh terhadap hasil belajar peserta didikKata Kunci : Pengaruh, Pendidikan Matematika Realistik, Hasil Belajar

Abstract

The purpose of this study is to identify the mathematical concepts involved in the craft of weaving belungkur in the Penjulung Hamlet community in Teluk Keramat district, Sambas Regency. The research method used was a descriptive exploratory ethnographic method. The subjects of this study were 2 weaving belungkur artisans. The data in this study are the results of interviews, observations, and recordings. The results obtained from this study are that the numbers mentioned in regional languages include one meaning one, dua' meaning two, tige meaning three, ammpat meaning four, limma' meaning five, annam meaning six, tujoh meaning seven, lapan meaning eight, semilan meaning nine. and sepuloh meaning ten. The results of the study also found that the shape of the curved surface was in the form of a rectangle and at the edges of the bend there was also a triangular shape. Measurements using the limbs such as the length of the hand is dapa' and finger is kilan. All the results obtained can be integrated into learning math at school.

Abstract

Mathematics learning has an essential role in forming and developing students' critical thinking skills. It is in line with the objectives of learning mathematics, which shows a logical, critical, analytical, careful, and thorough, responsible, responsive, and not easily give up in solving problems. Mathematics taught to students has the aim to equip students to have critical abilities. But in reality, the implementation of mathematics learning in schools has not been able to train students' critical thinking skills. This study aims to describe and find out the potential of students' critical thinking in solving problems in trigonometry in high school. The research method used in this research is descriptive with exploratory research. The subjects in this study were 30 subjects. Based on the results of this study, it was found that the potential for students' critical thinking in solving trigonometry problems was medium. Potential students' critical thinking is categorized as being because students have not been able to understand the problem displayed correctly, students have difficulty in giving arguments or reasons for the answers they have stated, students cannot identify and choose relevant information because of the available mathematical models, students have difficulty in giving questions to the information displayed.Keyword: Critical Thinking, Potential, Trigonometry

Abstract

This study aims to explain and describe the epistemological obstacle of students' mathematical conceptual understanding based on the SOLO taxonomy at MTs Negeri 2 Pontianak. This research uses a descriptive qualitative method with a survey form. The subjects of this research is 35 students in class VIII F MTs Negeri 2 Pontianak. Data collection techniques that used were test and and non-test. Data collection tools that used were conceptual understanding tests and interview. The results of data analysis from this study indicate that the epistemological obstacle of students' mathematical conceptual understanding based on the SOLO taxonomy from 35 students is 40% of students are in level 0 (prestructural); 11.43% of students are in level 1 (unistructural); 20% of students are in level 2 (multistructural); 25.71% of students are in level 3 (relational); and 2.86% of students are in level 4 (extended abstract). The obstacle of students that have at level 0 are all of conceptual understanding indicator. Students at level 1 and 2 have obstacles in indicators 2, 3, and 4. Students at level 3 have obstacles in indicators 2 and 4. Students at level 4 have obstacles in indicator 4.Keywords: Epistemological obstacle, Mathematical Conceptual Understanding, SOLO Taxonomy

Abstract

This study aimed to (1) determine the classification of students’ response in completing story questions based on the SOLO taxonomy; (2) discover the challenges of students in completing story questions on number patterns. The methodology used in this study was descriptive qualitative with a case study approach. The participants were 22 of 8th-grade students at SMP Sugiyopranoto Sanggau and the data sources were the results of story questions on number patterns and interview transcripts with the students. The result of this study indicates that response of high-achiever students reach the relational level of 8%, the students have already understand the number pattern materials quite well, take notes all the information contained on the questions, are able to correlate the separate information properly, write down the calculation steps and the conclusions given were also relevant. The response of moderate-achiever students reach the multistructural level of 40%, the students sufficiently understand the questions, take notes several important information and utilize it at the calculation, however, the correlation of separate information and concepts were not clear so that the calculation and the answers obtained were not reasonably right. Meanwhile, the response of low-achiever students are at the unistructural level of 21%, the students were still formula-oriented, and used merely one concept or one calculation step which caused the results obtained to be incorrect.

Abstract

This study aims to describe how high school students learned trigonometric comparison material in right triangles online and at home during the Covid-19 pandemic in the context of their level of conceptual mathematical understanding. Survey methods are combined with descriptive research methods in this type of study. This information comes from the results of tests and interviews with 32 Grade XI SMA Negeri 7 Pontianak students about a wide range of topics. The designed tool is a test that is related to the problem of understanding mathematical concepts for the purposes of this study. It is given to the research subjects and six students are chosen for the interview process. The findings of the research revealed that even in the midst of this epidemic, the level of conceptual understanding of mathematics students learning online remains low.
