The purposes of this research is to the differences in mathematical problem-solving skills enhancement and self-efficacy among students who had learned Realistic Mathematics Education (RME) approach and students who received conventional instructions. Reseach use quasi-experimental was used pre-test research design posttest control group design. The experimental group was treated using RME approach while the control group gain use conventional approach. To gather the instrument is the form of mathematical problem solving ability test, and a questionnaire to determine students' self-efficacy toward mathematics. This research was conducted at Secondary Islamic School . The population is grade VIII students MTsN Model Banda Aceh inl year 2012/2013. The samples were two classes, VIII-7, class as the experimental class and the control class VIII-6, by purposive sampling technique. The researc found that studens mathematical problem-solving ability which were taken by with RME approach better than conventional approaches. Based on the analysis of self-efficacy RME class increases more than the self-efficacy of students who received conventional learning. Furthermore there a relationship between the ability of solving mathematical problems with self-efficacy of students in the experimental class and control with very low qualifications.
The purpose of this research was to find out the increase in the ability to understand mathematical concepts of students who were taught with better Conceptual Understanding Procedures (CUPs) models than students who were taught with convensional model on the material of flat side space in MTsS Dama Puteh. The CUPs models has three stages including: individual, triplets, and class discussions. The author uses an experimental research design with a quasi-experimental design. Sampling was done using population random sampling. In this study all students of class VIII MTsS Dama Puteh. In this study consisted of two classes, namely class VIIIB as an experimental class and class VIIIA as a control class. Data collection using the ability test mathematical concept understanding of the results showed that based one the t-test obtained tcount = 1,8 and ttable = 1,68. Because tcount > ttable so that it can be concluded that the increased ability of understanding mathematical concepts of students taught with more CUPs models better than students who were taught with convensional models on the material to build flat side spaces in MTsS Dama Puteh.
Berdasarkan hasil penelitian dan pembahasan tentang kemampuan representasi matematis siswa melalui model PBL, maka diperoleh kesimpulan bahwa siswa yang berkemampuan tinggi dan sedang memenuhi ketiga indikator kemampuan representasi matematis yaitu menuliskan langkah-langkah penyelesaian masalah matematika dengan kata-kata, menyajikan data atau informasi dari suatu masalah ke representasi gambar, diagram, grafik atau tabel , serta menyelesaikan masalah yang melibatkan ekspresi matematis. Siswa berkemampuan rendah memenuhi dua indikator kemampuan representasi matematis yaitu menuliskan langkah-langkah penyelesaian masalah matematika dengan kata-kata dan menyelesaikan masalah yang melibatkan ekspresi matematis. Disarankan kepada pihak lain untuk melakukan penelitian yang sama pada materi yang berbeda sebagai bahan perbandingan dengan hasil penelitian ini atau materi yang sama namun mendapatan nilai N-Gain dengan kategori “tinggi”.Terima kasih kepada seluruh pihak yang telah ikut serta membantu dan mengevaluasi jurnal ini. terima kasih kepada pembimbing, guru disekolah para dosen dan juga teman-teman semua. Semoga jurnal ini bermanfaat.
Tujuan penelitian ini adalah untuk mendeskripsikan proses berpikir siswa terhadap kemampuan representasi matematis ditinjau dari gaya belajar visual. Penelitian ini merupakan penelitian kualitatif deskriptif dengan subjek pada penelitian ini adalah siswa yang cenderung memiliki gaya belajar visual pada kelas IX-5 di MTsN 1 Banda Aceh yang terdiri dari 3 orang siswa dengan kemampuan representasi matematis rendah, sedang dan tinggi. Pengumpulan data dilakukan melalui angket gaya belajar, soal tes kemampuan representasi matematis dan wawancara. Selanjutnya analisis data dengan mereduksi data, menyajikan data, melakukan trianggulasi waktu dan menarik kesimpulan. Hasil penelitian menunjukkan bahwa (1) proses berpikir subjek dengan kemampuan representasi matematis rendah dapat dilihat dari proses akomodasi pada ketiga indikator representasi matematis yaitu representasi simbolik, representasi verbal dan representasi visual; (2) proses berpikir subjek dengan kemampuan representasi matematis sedang dapat dilihat dari proses asimilasi dan akomodasi pada ketiga indikator representasi matematis; (3) proses berpikir subjek dengan kemampuan representasi matematis tinggi dapat dilihat dari proses asimilasi pada ketiga indikator representasi matematis.Kata kunci: Proses Berpikir., Kemampuan Representasi Matematis., Gaya Belajar Visual.
This study aims to identify students’ errors in solving problem equals to PISA’s based on Newman procedures. Qualitative-descriptive research was used in conducting this study and the subjects were third-grade students at SMP Unggul Sigli in year 2017/2018. Data was collected using tests and interviews. The instrument of this study was a sheet consisting of 5 (five) mathematical questions that composed equivalent to PISA’s problem. Analyzing students’ errors was guided by analyzing procedures developed by Newman which contain 5 (five) kinds of error, they are (1) reading error; (2) understanding error; (3) transformation error; (4) processing skill error; and (5) writing error. The result showed the percentage of each kind of errors made by students which detailed as follows, reading error comprised 37,1% of students; error in problem understanding made up 47%; 73% of subjects made error in transforming; 80% of students had error in processing; and error in writing final answer made up 78,1% of them. By analyzing the percentage, it is identified that the three most common mistakes are processing error, transformation error, and error in writing a final answer.
