Characteristics of Students In Resolving Word Problems Based on Gender

This study aims to analyze student errors in resolving word problems, which are then formulated into characteristics of student errors according to gender. The subject selection was done randomly from male and female students of grade VII who made mistakes in solving the questions. Research data from the test results of 2 items word problem type. The form of student error is based on misconceptions, procedures, and techniques. The results showed the students' misconceptions, don’t understand question commands, do not write information correctly, misinterpret question information, do not simplify fractions correctly, do not understand the value of fractions, misunderstand number signs/symbols and do not understand number signs/symbols, incorrectly determine signs/symbols of operations. Procedural error, incorrectly determining the settlement operation Technical errors, incorrectly using calculation operation marks, incorrectly performing calculation operations, incomplete settlement steps, incomplete simplification, incorrect simplification. Technical errors, namely calculations are not in accordance with the command, less careful (careless) writing answers, errors in writing answers and it do not match the command questions (conclusion). The reason is not understanding the reading and not being familiar with the questions. Students' understanding and knowledge of reading have an important role in identifying, interpreting, and even selecting or determining completion strategies

Transisi Representasi Simbolik-Pictorial dalam Menyelesaikan Masalah Matematika

The purpose of this study is to describe the transition process of symbolic-pictorial representation in solving mathematical problems. Data collection is done by giving written questions which are then followed by structured interviews. The subjects in this study involved seventh grade students who were selected with the consideration that the answers could provide a representations transition process. The results of this study indicate two representations transition processes, namely pictorial to symbolic and symbolic to pictorial. The pictorial-symbolic representation, starting with translating the problem information into the form of an image illustration through the difference in size and number of cakes, integrating the illustrations made through calculations by partitioning them into several equal parts using cutting lines as a modification/simplification process. Symbolic-pictorial representation, shown by finding the key to the problem "cakes are given evenly to 20 people" and translating the information into the form of calculations, then transforms by simplifying the calculation results based on the problem key, the results are translated into an illustrated circle-shaped image which is modified by partitioning it into several parts. The representation relationship shown through the form of symbolic calculations with picture illustrations has the same solution or not. Thus, the difference in the transition process of this representation is in the integration and translation stages of transformation and modification through changing physical forms (illustration of images) and symbols (calculations).Tujuan penelitian ini untuk menggambarkan proses transisi representasi simbolik-pictorial dalam penyelesaikan masalah matematika. Pengumpulan data dilakukan dengan memberikan soal tertulis yang dilanjutkan dengan wawancara terstruktur. Subjek pada penelitian ini melibatkan siswa kelas VII yang dipilih berdasarkan pertimbangan hasil jawaban siswa tersebut dapat memberikan proses transisi representasi. Hasil penelitian ini menunjukkan dua proses transisi representasi yaitu pictorial ke simbolik dan simbolik ke pictorial. Representasi pictorial-simbolik, dimulai dengan mentranslasikan informasi soal ke bentuk ilustrasi gambar melalui perbedaan ukuran dan banyaknya kue, mengintegrasikan ilustrasi yang dibuat melalui perhitungan dengan cara mempartisi menjadi beberapa bagian yang sama menggunakan garis-garis pemotongan sebagai proses modifikasi/penyederhanaan. Representasi simbolik-pictorial, ditunjukkan dengan menemukan kunci permasalahan “kue diberikan secara merata kepada  orang” dan mentranslasikan informasi ke bentuk perhitungan, kemudian mentransformasikan dengan menyederhanakan hasil perhitungan berdasarkan kunci permasalahan, hasilnya ditranslasikan ke bentuk ilustrasi gambar berbentuk lingkaran yang dimodifikasi dengan mempartisi menjadi beberapa bagian. Hubungan representasi yang ditunjukkan melalui bentuk perhitungan simbolik dengan ilustrasi gambar memiliki kesamaan solusi atau tidak. Dengan demikian perbedaan proses transisi representasi ini di tahap integrasi dan tranlasi pada transformasi dan modifikasi melalui pengubahan bentuk fisik (ilustrasi gambar) dan simbol-simbol (perhitungan)
