Abstract

Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mendeskripsikan bentuk dan alasan penggunaan dua bahasa (bahasa Indonesia dan bahasa konjo) dalam pembelajaran matematika. Subjek penelitian adalah guru dan siswa kelas VII di SMPN 1 Tombolopao. Data diperoleh dengan menggunakan Instrumen penelitian, yaitu observasi dan wawancara. Hasil penelitian menunjukkan bahwa dengan menggunakan dua bahasa dalam pembelajaran matematika yang berhubungan dengan kalimat diubah menjadi bahasa Konjo dan bahasa sehari-hari siswa. Penggunaan Bahasa Indonesia digunakan saat guru menjelaskan materi dan saat guru mengadakan evaluasi pada siswanya, guru akan membimbing siswa dengan menggunakan bahasa Konjo. Selanjutnya, bahasa Konjo digunakan saat guru ingin menyampaikan hal-hal penting yang menekankan penjelasan dalam kalimat Konjo. Faktor penyebab penggunaan komunikasi dua bahasa antara guru dan siswa dalam pembelajaran matematika adalah terbatasnya penggunaan Bahasa dengan alasan sebagai berikut; 1) Membantu siswa memahami materi yang diajarkan dengan menggunakan bahasa sehari-hari. 2) Guru merasa ada jarak dengan siswa saat menggunakan bahasa formal. Maka guru mengajak siswa untuk mengekspresikan pendapat mereka dalam bahasa yang sering digunakan. 3) Sifat Siri' dan Sipakatau dialami oleh siswa.

Abstract

Proporsi merupakan salah satu topik matematika yang mulai diajarkan di tingkat sekolah dasar. Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mengetahui dan menggambarkan bagaimana siswa sekolah dasar kelas 5 memecahkan masalah kontekstual proporsi ditinjau dari perbedaan kemampuan matematika. Subjek penelitian ini adalah siswa kelas 5 SD yang terdiri dari kemampuan matematika rendah, sedang, dan tinggi. Instrumen penelitian yang digunakan adalah Soal tentang konsep proporsi. Hasil menunjukkan bahwa subjek dengan kemampuan matematika rendah tidak menggunakan konsep proporsi untuk menyelesaikan masalah terkait perbandingan. Subjek tersebut hanya membandingkan antara kuantitas yang satu dengan kuantitas yang lain secara langsung. Subjek dengan kemampuan matematika sedang mampu menggunakan konsep proporsi untuk menyelesaikan masalah terkait perbandingan. Akan tetapi, mereka belum menunjukkan alasan yang kuat dalam hal membandingkan tiga buah kuantitas. Subjek dengan kemampuan matematika tinggi mampu menggunakan konsep proporsi untuk menyelesaikan masalah terkait perbandingan. Subjek tersebut mampu membandingkan ketiga kuantitas dalam masalah yang diberikan.

Abstract

The purpose of this research was to describe the errors of the eighth grade students of SMP Negeri 33 Makassar in solving the two-variable linear equation system problem based on the Newman stage. This type of research was a descriptive research with a qualitative approach. The data collection in this research was conducted by using the assignment and interview methods. The research subjects were taken by 4 people from students of class VIII-F, each consisting of 2 students who had the most errors and 2 students who had the least errors. Each research subject was interviewed based on the results of his work on two-variable system of linear equations. Testing the validity of the data by using the time triangulation technique. From the research results, it could be concluded that in the first and second assignments, all subjects had no errors at the reading and comprehension error stages of the questions. There was one subject who got a transformation error, namely the GAG (male) subject and the other subject did not get an error in the part of changing the problem into the correct mathematical model. As many as two subjects got errors in process skills, namely HKR (female) subjects and GAG (male) subjects and other subjects did not get errors in this section. There were two subjects who got errors in the error because the subject was wrong in the process skills, so the subject got an error at the encoding error stage
