Abstract

The problem raised in this research is that students' ability in making mathematical connections is still relatively low. This is because some of the theories in the learning of teachers still enjoy this way of learning, meaning that the students are only recipient of information without inspiration to active. Therefore, the authors are interested to conduct research by applying an NHT cooperative model setting to improve mathematical connection ability of junior high school students. This study aims to determine whether the knowledge of mathematical connections of junior high school students using learning methodology is better than junior high school students using ordinary learning. This research was conducted in SMP Krida Utama Padalarang Class VII, with research method the research used is quasi-experimental method. The sample of this research is taken two classes namely class VII A as experiment class and class VII B as control class. The research instrument is a set of mathematical connection test questions consisting of 5 test questions, and then tested by using a statistical test of differential. Based on the results of research and data processing, the authors conclude that the ability of mathematical connections of junior high school students whose learning using open-ended approach with learning model setting NHT type cooperative learning is better than the mathematical connection ability of junior high school students whose learning using ordinary learning.

Abstract

Penelitian ini dilakukan untuk menganalisis kesalahan siswa dalam menyelesaikan soal kemampuan koneksi matematis pada materi bangun datar segi empat, subjek penelitian yaitu siswa kelas VIII dari salah satu SMP Negri di Cimahi sebanyak 29 siswa. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif dengan pendekatan kualitatif, instrumen yang digunakan yaitu sebanyak empat butir soal dengan kemampuan koneksi matematis siswa. Berdasarkan hasil penelitian ini dapat disimpulkan kesalahan dalam menyelesaikan soal kemampuan koneksi matematis pada materi bangun datar segi empat untuk setiap indikatornya masih tinggi. Pada indikator pertama yaitu mengidentifikasi hubungan berbagai representasi konsep dan prosedur matematika pada soal nomor tiga memperoleh persentase kesalahan sebesar 63%. Untuk indikator kedua yaitu mengidentifikasi hubungan satu prosedur ke prosedur lain dalam represen-tasi yang ekuivalen pada soal nomor satu memperolah persentase kesalahan sebesar 24% dan soal nomor empat memperoleh persentase kesalahan sebesar 40%. Dan indikator ketiga yaitu menjelaskan penerapan topik matematika dalam masalah kehidupan sehari-hari pada soal nomor dua memperoleh persentase kesalahan sebesar 43% Kata kunci: Analisis kesalahan, Kemampuan koneksi matematis, Bangun datar segi empat
