Abstract

Kemampuan menyelesaikan masalah kontekstual dapat memberikan manfaat bagi siswa yaitu siswa mengetahui apa kegunaan dari pokok bahasan yang telah dipelajari dan kemampuan dalam mengambil suatu keputusan. Kesulitan dalam menyelesaikan masalah kontekstual merupakan suatu masalah yang perlu ditangani pemecahannya. Tujuan dari penelitian ini yaitu mendeskripsikan jenis kesalahan siswa dalam menyelesaikan masalah kontekstual pada materi aritmetika sosial berdasarkan  Newman?s Eror Analysis (NEA) yang terdiri dari 5 jenis kesalahan. Subjek penelitian ini adalah 30 siswa kelas VII SMP Negeri 2 Kuala Indragiri yang terdiri dari 8 siswa kemampuan tinggi, 10 siswa berkemampuan sedang, dan 12 siswa berkemampuan rendah. Metode penelitian yang diterapkan yaitu deskriptif kualitatif. Instrumen yang digunakan yaitu berupa tes soal. Dari hasil analisis diperoleh tidak terdapat siswa yang melakukan kesalahan membaca dikarenakan siswa telah mampu membaca simbol-simbol pada soal dengan benar. Siswa melakukan kesalahan pada memahami masalah sebesar 26.61%, transformasi masalah sebesar 28.51%, keterampilan proses sebesar 22.05%, dan kesalahan pada penarikan kesimpulan sebesar 22.43%. Faktor penyebab ialah siswa belum dapat memahami informasi yang terdapat dalam soal, lupa cara yang digunakan dalam menyelesaikan soal, kurang teliti dalam perhitungan dan tidak dapat menarik kesimpulan dari penyelesaian soal.

Abstract: This research is a class action research. This research aims to improve the learning process and improve learning result in mathematics in grade X MIA 4 of SMA Negeri 5 Pekanbaru by applying the Discovery Learning model. The subject of this research were the students in the class X MIA 4 of SMA Negeri 5 Pekanbaru that consist of 19 boys and 21 girls at the second semester of academic year 2016/2017. Implementation of the learning process before held action, there is a problem of learning that is still focused on the teacher so that students can not find the concept of learning. To solve this problem requires a learning model where students can actively discover teir own learning concepts. The instruments of data collection in this research were observation sheets and students mathematic tests. The observation sheets were analyzed in desciptive narative, while the students’ mathematic tests were analyzed in statistic desciptive. The descriptive showed an improvement of learning process prior to the action on the first and second cycles and improve the students’ achievement of learning mathematic in grade X MIA 4 of SMA Negeri 5 Pekanbaru in the second semester academic years 2016/2017.Keywords : Students’ Math Achievement, Discovery Learning Model, Clasroom Action Research.
