Abstract

Selama proses belajar mengajar matematika, siswa juga menghadapi banyak kendala terkadang siswa tahu cara menjawab pertanyaan yang diajukan, namun melakukan kesalahan dalam perhitungan. Tujuan penelitian ini adalah untuk mengetahui kesalahan siswa dalam menyelesaikan soal cerita SPLTV berdasarkan Metode Newman. Penelitian ini menggunakan deskriptif dengan pendekatan kualitatif. Subjek dalam penelitian diambil secara purposive sampling yang terdiri dari 10 orang siswa SMA. Teknik pengumpulan data menggunakan soal tes uraian. Hasil penelitian menunjukkan bahwa siswa melakukan Reading Error sebanyak 13,40%, Comprehention error sebanyak 21,65%, Transformation error sebanyak 19,59%, Process skill error sebanyak 19,59%, Endcoding error sebanyak 25,77%. Hal ini terjadi karena siswa kurang teliti, tidak mampu membaca soal, tidak memahami masalah, dan tidak mampu melakukan prosedur yang akan digunakan untuk menyelesaikan soal.During the process of teaching and learning mathematics, students also face many obstacles. Sometimes students know how to answer the questions asked, but make mistakes in the calculations. The purpose of this study was to find out students' mistakes in solving SPLTV story problems based on the Newman Method. This research uses descriptive with a qualitative approach. Subjects in the study were taken by purposive sampling consisting of 10 high school students. Data collection techniques using essay test questions. The results showed that students made reading errors of 13.40%, completion errors of 21.65%, transformation errors of 19.59%, process skill errors of 19.59%, endcoding errors of 25.77%. This happens because students are less thorough, unable to read the questions, do not understand the problem, and are unable to carry out the procedures that will be used to solve the problem.

Abstract

Kemampuan pemecahan masalah diharapkan dapat dikembangkan secara optimal pada siswa, namun fakta menunjukkan kemampuan pemecahan masalah matematika siswa masih rendah. Diperlukan upaya mengatasi masalah tersebut misalnya dengan menerapkan model Pembelajaran Berbasis Masalah. Tujuan penelitian ini adalah untuk mendeskripsikan kemampuan siswa yang dibelajarkan dengan model pembelajaran berbasis masalah dan kemampuan siswa yang dibelajarkan dengan pembelajaran biasa dalam pembelajaran matematika. Penelitian dilakukan di salah satu SMA swasta di Padang, dengan sampel yaitu kelas XI IPA 3 dan XI IPA 4. Metode penelitian yang digunakan yaitu kuasi eksperimen. Data dikumpulkan dari instrumen tes berbentuk soal uraian sebanyak 8 butir soal. Analisis data dilakukan secara deskriptif. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah matematika siswa yang dibelajarkan dengan model Problem Based Learning lebih baik daripada kemampuan pemecahan masalah matematika siswa yang dibelajarkan melalui pembelajaran biasa. Pembelajaran berbasis masalah dapat dijadikan salah satu alternatif dalam mengembangkan kemampuan pemecahan masalah siswa SMA.Problem-solving abilities are expected to be optimally developed in students, but the facts show that students' mathematical problem-solving abilities are still low. Efforts are needed to overcome these problems, for example by applying the Problem-Based Learning model. The purpose of this study was to describe the abilities of students with problem-based learning models and with ordinary learning in mathematics learning. The study was conducted at a private high school in Padang, with the samples being class XI IPA 3 and XI IPA 4. This study used the quasi-experiment method. The data was collected from the test instrument in the form of a description of 8 questions. Data analysis was carried out descriptively. The results showed that the mathematical problem-solving abilities of students with the Problem-Based Learning model were better than the problem-solving abilities of students with ordinary learning. Problem-based learning can be used as an alternative to developing high school students' problem-solving abilities.
