Abstract

Translation among multiple representations is one of the important abilities to be possessed by prospective mathematics teachers. The mathematics learning curriculum ranging from elementary to college level needs to emphasize the ability to translate mathematical ideas in a form of representation to different mathematical representation structures. Assessing of this ability is important because it can be used as a basis for developing other mathematical literacy skills. The purpose of this study is to describe the level of translation between mathematical representations of prospective mathematics teachers. A descriptive qualitative study was conducted to fourty prospective mathematics teachers in State Islamic University of Mataram. The selection of research subjects was carried out in a purposive sampling. Data were obtained from mathematical translational thinking task in the form of an assignment sheet consisting of 2 questions related to quadratic equations and task-based interviews. Data were analyzed using fixed comparison analysis, which is comparing incidents (phenomena) with the aim of classifying data. The study found five levels of translational ability between mathematical representations, which were named: level 0, level 1, level 2, level 3 and level 4. The characteristics of each level are built based on four mathematical translational thinking processes: unpacking the source of representations, coordinating initial stage, design the target representation and determine the equivalence between the source and target representations. The findings in this study could be used as a guide to develop an instrument to assess mathematical translation ability.

Abstract

Abstrak: Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek dalam penelitian ini  adalah lima orang perempuan dan lima orang laki-laki siswa VII. Peneliti menggunakan langkah-langkah menurut Soedjadi, (a) Membaca soal dengan cermat untuk menangkap makna tiap kalimat, (b) Memisahkan dan mengungkapkan apa yang diketahui dalam soal, apa yang diminta/ditanyakan dalam soal, operasi pengerjaan apa yang diperlukan, (c) Membuat model matematika dari soal, (d) Menyelesaikan model menurut aturan-aturan matematika, sehingga mendapatkan jawaban dari model tersebut, dan (e) Mengembalikan jawaban soal kepada jawaban asal. Hasil penelitian menunjukkan siswa perempuan mengalami kesulitan dalam memahami konsep pecahan (menyamakan penyebut), mengalami kesulitan dalam menentukan operasi pengerjaan seperti penjumlahan, pengurangan, perkalian dan pembagian serta tidak menuliskan kesimpulan terakhir sedangkan siswa laki-laki mengalami kesulitan dalam memahami soal sehingga kurang tepat dalam menyelesaikan hasil akhir serta menyamakan penyebut. Cara mengatasi faktor-faktor kesulitan dalam soal ceritaa matematika adalah memberikan intensitas latihan, menguatkan kembali konsep pecahan pada siswa perempuan dan meningkatkan komunikasi matematis siswa.Abstract:  This research is a qualitative descriptive study. The subjects in this study were five women and five male students VII. The researcher uses the steps according to Soedjadi, (a) Read the questions carefully to capture the meaning of each sentence, (b) Separate and reveal what is known in the question, what is asked / asked in the question, what work operation is needed, (c) Make a mathematical model of the problem, (d) Complete the model according to mathematical rules, so that the answer to the model is obtained, and (e) Return the answer to the original answer. The results showed that female students had difficulty understanding the concept of fractions (equating the denominator), had difficulty in determining work operations such as addition, subtraction, multiplication and division and did not write the final conclusions while male students had difficulty understanding the problem so that it was not correct the final result and equate the denominator. The way to overcome the difficulty factors in mathematical storytelling is to provide training intensity, reinforce the concept of fractions in female students and improve students' mathematical communication.
