Abstract

The purpose of this study is to analyze and find out the mathematical communication skills of junior high school students by using a scientific approach to the material of straight-line equations. This research consists of two cycles based on the Kemmis & Taggart model. which consists of: planning, implementation, observation, and reflection. The subject of this study was 30 students of VIII grade from SMP IT Budi Luhur Cimahi of 2021/2022 academic year. The test instrument used in accordance with the indicators of mathematical communication ability is in the form of a description of as many as 5 numbers. Normalized gain data was generated in this study, resulting in a score of 0.36. Data processing in the study was obtained from normalized gain data, with a score of 0.36. This shows that students' mathematical communication skills have improved, with a moderate category. The non-test instruments used included a questionnaire on the scale of learning interest attitudes as many as 16 balanced statements with positive and negative responses. The results of the response to students' interest in learning mathematics have a positive effect on students' mathematical communication, namely 76.6 with a positive category.

Abstract

With the help of teaching aids, this study intends to show how mathematics learning outcomes among students have improved. The sub-material used in this study is about slices and combinations. The venn diagram board is the teaching aid used in this research. This type of research is a Classroom Action Research (CAR) which was conducted in one of the junior high schools in Purwakarta Regency by involving 20 students of class VII as research subjects. The data collection technique used in this research is using a written test (daily test) in the form of a description of 8 items. Processing of data from the results of the written test in this study is using the percentage formula. Based on the data analysis of students' mathematics learning outcomes, namely a) In the first cycle there were 6 students (30%) who completed and 14 students (70%) did not complete, b) In the second cycle there were 12 students (60%) who completed and 8 students (40%) which are not completed. So based on the results of the analysis obtained from this study, it can be seen that learning by using teaching aids media can improve student learning outcomes.

Abstract

Siswa harus memiliki kemampuan memahami matematika karena belajar matematika tidak hanya tentang menghafal rumus dan berhitung, tetapi juga tentang memahami konsep. Tujuan penelitian ini adalah untuk mengetahui pemahaman matematis siswa pasca pandemi Covid-19 dengan persamaan kuadrat. Jenis penelitian ini bersifat kualitatif dengan populasi 30 siswa dan sampel 10 siswa kelas IX yang dilakukan di SMPN 8 Cimahi. Instrumen yang digunakan adalah tes pemahaman matematika. Data yang diperoleh dari hasil tes diolah dalam tiga tahap, yaitu reduksi data pertama (analisis jawaban siswa), presentasi kedua, dan ketiga penarikan kesimpulan peneliti. Hasil penelitian menunjukkan bahwa 10% siswa yang memiliki kemampuan matematika termasuk dalam kategori sangat tinggi dan sangat rendah, 20% termasuk dalam kategori tinggi dan rendah, dan 40% siswa termasuk dalam kategori sedang. Penelitian ini menunjukkan bahwa kemampuan pemahaman matematis siswa masih perlu dikembangkan karena siswa masih belum memahami materi dan belum terbiasa mengerjakan soal pemahaman matematika sehingga tetap melakukan kesalahan saat menyelesaikan soal.

Abstract

Students must have the ability to understand mathematics because learning mathematics is not only about memorizing formulas and counting, but also about understanding concepts. The purpose of this study is to determine the mathematical understanding of students after the Covid-19 pandemic with quadratic equations. This type of research is qualitative with a population of 30 students and a sample of 10 class IX students conducted at SMPN 8 Cimahi. The instrument used is a mathematical comprehension test. The data obtained from the test results are processed in three stages, namely first data reduction (analysis of student answers), second presentation, and thirdly drawing researchers' conclusions. The results showed that 10% of students who have mathematical ability belong to the very high and very low categories, 20% belong to the high and low categories, and 40% of students belong to the medium category. This research shows that students' mathematical comprehension skills still need to be developed because students still do not understand the material and are not used to doing mathematical comprehension questions so they still make mistakes when solving problems.

Populasi penelitian adalah seluruh mahasiswa pendidikan matematika STKIP Siliwangi Bandung yang mengikuti mata kuliah kapita selekta matematika. Populasi penelitian adalah seluruh mahasiswa pendidikan matematika STKIP Siliwangi Bandung yang mengikuti mata kuliah aljabar umum  menengah pada semester ganjil Tahun Ajaran 2015/2016 yang terdiri dari 3 kelas, yaitu: A1 A2 dan A3. Sampel penelitian dipilih 2 kelas dari populasi penelitian, terpilih kelas A1 sebagai kelas kontrol yang terdiri dari 35 orang mahasiswa dan kelas A3 sebagai kelas eksperimen yang terdiri dari 34 orang mahasiswa. Sampel dipilih dengan teknik cluster random sampling karena semua kelas memiliki karakteristik dan kemampuan akademik yang setara. Analisis data dilakukan terhadap gain hasil tes kemampuan mahasiswa mata kuliah aljabar umum. Untuk memperoleh data penelitian digunakan instrumen berupa tes, non tes dan skala self efficacy. Analisis penelitian menggunakan uji perbedaan rata-rata. Hasil penelitian didapat kesimpulan: (i) Pencapaian dan peningkatan kemampuan pemecahan masalah yang mendapat pembelajaran PBL lebih baik daripada mahasiswa yang mendapat pembelajaran ekspositori (ii) self efficacy matematik mahasiswa yang pembelajarannya menggunakan PBL lebih baik daripada siswa dengan pembelajaran yang menggunakan pendekatan ekspositori. Kata Kunci: Pembelajaran PBL, Self Efficacy, Pemecahan Masalah

Abstract

The purpose of this study was to find out the difficulties faced by students in the ability to solve mathematical problems of Straight Line Equation material. This type of research is descriptive qualitative, and data collection is carried out as instrumental questions with 4 questions. The subjects of the study were class VIII students numbering 10 people. The results of the researcher's analysis showed that students’ mathematical problem solving abilities in straight line equation material were still low. Students difficulties in reading problems in this straight line equation material, students having difficulty reading graphs on the questions presented, students' lack of understanding of constructing known and asked data used to solve problems, difficulties in determining formulas that are appropriate to the questions presented, lack of accuracy and ignorance of the prerequisite material related to the problem, and answering questions at random, so that students cannot solve them correctly. This difficulty is caused by students' lack of accuracy when reading questions in the form of descriptions, not paying attention to the teacher when explaining and not understanding graphical questions and the way students think about mathematical problems is difficult.
