Abstract

Tujuan dari penelitian ini yaitu untuk mengetahui kemampuan komunikasi matematik siswa SMP dalam menyelesaikan soal lingkaran. Subjek penelitian yaitu siswa kelas IX dari salah satu SMP Negeri di Cimahi tahun ajaran 2017/2018. Metode dalam penelitian ini adalah deskriptif kualitatif. Untuk mendapatkan data dalam penelitian ini, digunakan 6 tes soal uraian kemampuan komunikasi matematik dan wawancara. Berdasarkan pada hasil penelitian ini, dapat disimpulkan bahwa  kemampuan komunikasi matematik siswa belum mencapai hasil yang maksimal terutama pada kemampuan mejelaskan ide, situasi matematik secara tulisan dengan gambar, dan aljabar; kemampuan menyatakan peristiwa sehari-hari dalam bahasa simbol matematika, dan kemampuan membuat konjektur, menyusun argumen dan generalisasi, serta membuat pertanyaan tentang matematika yang telah dipelajari. Penyebab siswa belum memiliki kemampuan komunikasi matematik yang baik adalah siswa menganggap menuliskan apa yang diketahui dan ditanyakan itu merupakan hal yang tidak penting. Siswa kurang memahami konsep dasar dalam melakukan proses operasi hitung baik dalam bentuk aljabar maupun operasi hitung matematika yang lain. Siswa cenderung ceroboh dalam mengerjakan soal karena ingin cepat selesai dan kurangnya konsep pemahaman mengenai materi lingkaran. Kata kunci: kemampuan komunikasi matematik, materi lingkaran. ABSTRACT This study aims to analyze the mathematical communication ability of junior high school students in solving circle problems. The research subjects are ninth grade students from one of State Junior High School at Cimahi in the academic year 2017/2018. The method of this research is qualitative descriptive. The data are obtained from the analysis of 6 mathematical communication skill tests and interview. Based on the result of the research, it can be concluded that the students’ mathematical communication ability has not achieved optimal results, especially in the ability to explain ideas, mathematical situation in writing with pictures, and algebra; the ability to express everyday events in the language of mathematical symbols; and the ability to make conjectures, to formulate arguments and generalizations, and to form a questions based from the previous topics have been learned. The students do not have a good mathematics communication ability because they assume that writing down anything given and asked is not important. Students do not understand the basic concept of algebraic operation or other mathematical operations. Students tend to be careless in working because they want to finish quickly and they need better concept to understand the circle topics. Keywords: mathematical communication ability, circle topics.

Abstract

Penelitian ini bertujuan melihat adakah  pengaruh positif self confidence siswa SMP terhadap kemampuan berpikir kritis matematis. Subjek penelitian yang diambil 30  siswa kelas  IX di salah satu SMP swasta di Kota Cimahi. Metode yang digunakan pada penelitian ini yaitu metode korelasional dengan pendekatan kuantitatif. Instrumen dalam penelitian ini meggunakan  tes kemampuan berpikir kritis matematis dan angket self confidence. Tes kemampuan berpikir kritis matematis terdiri dari 4 butir soal yang diadopsi dari Yulia (2015) dan angket self confidence  terdiri dari 41 skala pernyataan yang diadopsi dari Sumarmo (2015) dengan indikator : a) percaya kepada kemampuan sendiri, tidak cemas, merasa bebas, dan bertanggung jawab atas perbuatannya. b) bertindak mandiri dalam mengambil keputusan. c) Memilih konsep diri yang positif, hangat dan sopan, dapat menerima dan menghargai orang lain. d) memiliki konsep diri yang positif, hangat dan sopan dapat menerima dan menghargai orang lain. e) berani mengungkapkan pendapat dan memiliki dorongan untuk berprestasi. f) saya mengenal kelebihan dan kekurangan diri sendiri. Hasil dari penelitian ini menunjukkan  self confidence siswa tidak  memiliki pengaruh terhadap kemampuan berpikir kritis matematis. Berdasarkan analisis lanjut penyebab self confidence yang kurang pada siswa dalam penelitian ini yaitu tidak ada motivasi siswa ketika menyelesaikan soal matematika. Jika siswa tidak memiliki motivasi dalam menyelesaikan soal matematika maka siswa itu tidak akan berani mengungkapkan pendapat dan memiliki dorongan untuk berprestasi (indikator self confidence). Yang dapat mempengaruhi siswa terhadap kemampuan berpikir kritis  yaitu kemauan dalam belajar dan menyelesaikan soal matematika, motivasi belajar dan self efficacy merupakan faktor-faktor lain yang dapat mempengaruhi kemampuan berpikir kritis siswa.

Abstract

This study aims to analyze the errors of grade IX students in MTs Negeri Cimahi in solving circle problems, 32 students, and 6 random samples were taken. The research approach used is qualitative research with descriptive methods. The research instrument used in the test is based on bloom's taxonomy on the dimensions of cognitive processes that begin with C1-C6, where C1 is remembering, C2 is understanding, C3 is applying, C4 is analyzing, C5 is evaluating and C6 is creating. The test is examined based on the type of error Watson category and an analysis of student answer errors. The results showed that the type of error that was very high was 60% in the Above Other / AO type. Then for Omitted Data / OD errors, including a low error of 20%. Types of errors in Inappropriate Data / ID included in the low error that is equal to 13% and the last type of errors in Inappropriate Procedure / IP including very low errors of 7%. While the types of Response Level Conflict / RLC, Undirected Manipulation / UM, and Skills Hierarchy Problem / SHP errors are 0%, respectively, including very small errors. The cause of students making mistakes in solving circle problems based on the Watson category errors is the lack of understanding of the concept of the material being taught, students cannot solve problems according to the solution procedures and the lack of accuracy of students in working on given problems.

Abstract

This study aims to explain the mistakes of junior high school students in solving social arithmetic story problems and analyze the factors. The research method taken is descriptive qualitative. The research subjects were seventh grade students of SMP Negeri 8 Cimahi. Data collection in this study was carried out by using a mathematical test method with four questions of social arithmetic and interviews with students who made mistakes. The data analyzed were taken from 10 students' answers by means of data analysis used for this study, namely data reduction, data presentation and conclusion drawing. After the tests and interviews were carried out, the results of the tests and interviews with student answers were analyzed and conclusions were drawn about what mistakes students often experienced in solving story questions on social arithmetic material. From the results of the study, it was shown that the students' mistakes in working on story problems on social arithmetic material were that students did not understand the problem because the social arithmetic material given was about story questions, errors in making mathematical models, namely: students made mistakes in operating the answers. on the questions, and errors in the process or steps of working on the questions, namely: writing down what is known and determining what is being asked. Therefore, the factors that often cause students to make mistakes are that there are still many students who do not understand the basic concepts, students are less thorough in understanding story questions, so students do not understand the concept of arithmetic operations well.

Abstract

Covid-19 is a rapidly growing outbreak around the world, one of the obvious impacts is the education sector. Inadequate education affects the learning outcomes of learners. One of the factors that affect student learning outcomes is the presence of motivation that comes from the student itself. Without the willingness to learn, it can be difficult for students to know what to learn and why they need to learn it. The research used is correlational and ex-post facto research using quantitative approaches that aim to find out whether students' learning outcomes in statistical material have an effect on learning motivation. The subjects used in the study were class IX students consisting of 6 students including 3 women and 3 men. Research instruments conducted using student motivation scale questionnaires and written tests of statistical material. The data analysis technique used in this study is a simple linear regression analysis using an average percentage of motivational indicators and spsss statistic 25 software. The results of the study proved that there was an influence of 62.2% between learning motivation and student learning outcomes.

Abstract

The research aims to investigate the achievement of students' mathematical representation abilities in the material of flat-sided space after receiving a problem-based learning model. This study employs a quasi-experimental method with a non-equivalent control group design, as there is no randomization of samples in both classes. The population consists of eighth-grade students at SMP Dharma Kartini, with the research sample being class VIII-A as the control group and class VIII-B as the experimental group, each consisting of 35 students. The instruments and learning tools used include pretest and posttest questions, as well as LKPD containing material on flat-sided space and the stages of the PBL model. The obtained data will be processed using statistical tests through a two-sample independent t-test, preceded by a normality test and followed by the Mann-Whitney test. The results of the study interpret that there is a difference in the achievement of students' mathematical representation abilities after the PBL model is applied to the flat-sided space material.

Abstract

Communication skill is an ability that needs to be possessed by students. Through communication, students can express their opinions or ideas to their friends or to the teacher. The facts in the field show that students' mathematical communication skills are in the low category, therefore a solution is needed to improve students' mathematical communication skills. This research aims to produce problem-based learning-based LKPD assisted by liveworksheets to hone students' mathematical communication skills. This research was conducted at SMPN 1 Ngamprah. The subjects of this study amounted to 10 students on a limited trial. 34 students for a broad trial. The method used is development research according to Sugiyono which is modified into 7 stages carried out due to time constraints, namely: potential and problems, data collection, product design, design validation, design revision, product trial, and product revision. Data collection tools for this study are validation sheets, student response questionnaires, and 5 questions about mathematical communication skills in statistics material. Based on the results of value processing from validators, it shows that the developed LKPD is said to be suitable for use in learning, with an average percentage of assessment from validators of 85%. The results of the calculation of student answers show that the developed LKPD is effective for improving mathematical communication skills, with an average calculation of each indicator of 72.35%.  It can be concluded that problem-based learning-based LKPD assisted by liveworksheets can be used in learning as an effort to improve students' mathematical abilities in statistics material.
