Abstract. This study aims to analyze the types of error and its factors that cause students’ error in solving operation research problems in the program linear topic based on Newman’s Error Analysis (NEA). This research is qualitative research by using a descriptive approach. The subjects in this study are fourth-grade college students in the Mathematics Education Program at State Islamic Institute of Kerinci that chosen by purposive sampling technique. The data was collected by using a test and interview. The data analysis was done descriptively. Based on the research findings, the types of students error in solving operation research problems were reading errors, comprehension errors, transformation errors, process skill errors, and encoding errors. The factors that cause the students' error were the students can not interpret, understand and understand the meaning of the questions overall; can not determine the formula to solve the problems; can not carry out the algorithm of arithmetic operations. Abstrak. Penelitian ini bertujuan untuk menganalisis jenis kesalahan dan faktor yang menyebabkan kesalahan mahasiswa dalam menyelesaikan soal riset operasi pada materi program linier berdasarkan Newman’s Error Analysis (NEA). Penelitian ini merupakan penelitian kualitatif dengan menggunakan pendekatan deskriptif. Subjek penelitian ini adalah mahasiswa semester IV program studi Tadris Matematika IAIN Kerinci tahun akademik 2018/2019 yang dipilih dengan teknik purposive sampling. Data dikumpulkan melalui tes dan wawancara dan dianalisis secara deskriptif. Berdasarkan temuan penelitian diketahui bahwa jenis kesalahan mahasiswa dalam menyelesaiakan soal riset operasi materi program linier berdasarkan Newman’s Error Analysis adalah kesalahan dalam membaca soal, kesalahan dalam memahami masalah, kesalahan dalam transformasi, kesalahan dalam keterampilan proses, dan kesalahan dalam penulisan jawaban akhir. Faktor-faktor penyebab kesalahan tersebut meliputi: mahasiswa tidak bisa memaknai, mengerti dan memahami makna keseluruhan dari soal yang berikan; tidak bisa menentukan rumus yang digunakan; dan tidak bisa menajalankan tahapan-tahapan operasi hitung yang digunakan untuk menyelesaikan soal.
Mampu memecahkan masalah adalah suatu kemampuan matematika yang penting dimiliki oleh siswa. Namun kenyataannya, kemampuan memecahkan masalah matematika dikalangan siswa masih tergolong rendah. Rendahnya kemampuan pemecahan masalah matematis dibuktikan dengan adanya penelitian-penelitian sebelumnya yang mengungkapkan bahwa kemampuan memecahkan masalah yang rendah dikarenakan pemilihan model pembelajaran yang kurang efektif dan relevan. Kurangnya keterlibatan siswa secara aktif dalam mengkontruksikan penegtahuan yang dimiliknya dalam proses belajar mengajar, menyebabkan rendahnya kemmapuan siswa dalam memecahkan masalah. Tujuan penelitian ini untuk menganalisis pengaruh model pembelajaran Teams Games Tornament (TGT) terhadap kemampuan pemecahan masalah matematis siswa kelas VIII SMP 24 Kerinci pada materi Relasi dan Fungsi. Penelitian ini merupakan penelitian eksperimen semu dengan pretes-postest. Instrument yang digunakan dalam penelitian ini adalah tes yang berupa 5 butir soal essay. Populasi penelitian ini adalah semua siswa kelas VIII SMP Negeri 24 Kerinci yang terdiri atas 2 kelas. Teknik analisis data dilakukan dengan menggunakan uji-t. Dari hasil perhitungan diperoleh rata-rata untuk kelas eksperiment 76,2 dan rata-rata untuk kelas kontrol adalah 65,08. kemudian dengan menggunakan uji t diperoleh thitung = 5,28 , sedangkan nilai ttabel = 1,668, karena thitung > ttable maka Ho ditolak dan H1 diterima. Hal ini berarti terdapat perbedaan kemampuan memecahkan masalah antara siswa yang menggunakan model pembelajaran TGT dengan yang menggunakan metode ceramah. Kata Kunci: Kemampuan Pemecahan Masalah, Teams Games Tournament, Metode ceramah
This study aimed to determine the effect of Gallery of Learning with Geogebra as active learning strategies on students’ learning motivation. This research was a quantitative study with the one grup pretest-posttest design. The population of this study was all eight-grade students of SMP Negeri 27 Kerinci. The sample consisted of 27 students which selected by saturated sampling techniques. Student motivation data were obtained from motivation questionnaires that given before and after the application of the Gallery of Learning with Geogebra as active learning strategy. Data processing of student motivation was done by comparing students' motivation scores before and after treatmen by, using the t-test. The t-test results indicated that there was influence on the implementation of the active learning strategy of Gallery of Learning with Geogebra on students' learning motivation.
Mathematics relation and function is one of important topics in junior high school. This study aims to see differences in the problem-solving a bilities of junior high school students who use the Model-Eliciting Activities (MEAs) and conventional models in learning mathematics relation and function. This research is a quantitative study using a quasi-experimental approach with a non-equivalent control group design. The population in this study was all of the seventh-grade students at a State Junior High School in Sungai Penuh, Jambi, Indonesia, and the sample was two groups experimental group and control group. The data collection technique used is a test of mathematical problem-solving skills. The data were analyzed by using he independent t-test to find comparisons or differences. The research result showed that there were differences in the mathematical problem-solving skills of junior high school students who used MEAs and other students who did not use MEAs. This difference occurs as a result of different treatment received by students, by MEAs students are required to be more active in understanding and formulating problems.
The objective of this research is to know the differences in mathematical problem solving skills between using mathematical habits of mind strategy with conventional learning. Methods that is used is quasi-experimental, with non-equivalent control group design. The subject of this study was a 7th grade junior high school student with 56 number of people which were 12th-13th years old. with sampling techniques i.e. purposive sampling. Instruments that is used in this research is description test which was arranged based on mathematical problem solving skills material. Data analysis technique is with N-Gain T-test. The result show that the significant N-Gain score obtained is 0.008. The N-Gain score is smaller tha (α = 0.05), which means that there is a significant difference in the increase in mathematical problem solving abilities toward participant student who use mathematical habits of mind strategies with those using conventional learning. statistically proven habits of mind strategy that influences problem solving can be one of the practitioners' choices in teaching mathematics in basic education.
Penelitian ini bertujuan untuk mengetahui aktivitas siswa selama proses pembelajaran menggunakan model pembelajaran kooperatif teknik Kartu Arisan. Selain itu juga bertujuan untuk mengetahui rata-rata hasil belajar matematika siswa menggunakan model pembelajaran kooperatif teknik Kartu Arisan. Jenis penelitian ini adalah penelitian eksperimen semu dengan model rancangan randomized control group only design. Hasil analisis data menunjukkan bahwa hasil belajar matematika siswa yang menggunakan model pembelajaran kooperatif teknik kartu arisan lebih baik dari pada hasil belajar matematika siswa yang menggunakan model pembelajaran biasa. Hasil analisis observasi menunjukkan bahwa persentase aktivitas siswa menggunakan model pembelajaran kooperatif teknik kartu arisan lebih baik dari pada persentase aktivitas siswa siswa yang menggunakan pembelajaran biasa.
