Communication Ability

The ability of mathematical communication is the skill to communicate mathematics that is learned and the skill of using mathematics as a communication tool (mathematical language). Mathematical communication skills are very necessary in learning. Without mathematical communication skills, a person will not be able to deliver statements according to their desire. This qualitative descriptive study aims to describe the level of mathematical communication ability of junior high school students in solving open ended problems with the topic of functional graphs. The method of collecting data through written tests and interviews. Written tests were given to 115 8th grade students of junior high schools in Surabaya, followed by interviews of one student at each level of mathematical communication ability. The results showed 51 people (44%) were at fourth level, 27 people (24%) at third level, 23 people (20%) at second level, and 14 people (12%) at first level. Students at fourth level and third level are equally able to use mathematical language that was accurate and effective, and appropriate in providing the strategies. But it was different in giving the arguments. Students at second level can not provide logical arguments, the mathematical language used was less effective and accurate, and the strategies used were precise but incomplete. Students at first level did not provide the right strategies because the lack of information which contained in the story, did not provide responses more to the stories they have been written, and did not demonstrate the ability to use mathematical language that was  accurate and effective.

One factor that has a big influence on mathematics learning outcomes and how students provide solutions to mathematical problems, among others, is the learning factor as well as initial mathematical knowledge (IMK). So, the objectives of the research are to find out: (1) the influence of the Realistic Mathematics Education (RME) Approach aided by Microsoft Mathematics software on students' mathematical communication ability (MCA), (2) an interaction between IMK and RME approach to mathematical communication ability, (3) the students' completion process in solving mathematical communication problems. The third objective is very important because it can reveal whether horizontal and vertical mathematization as the ideas of RME benefit the students. The results of the research show that: (1) there is a significant effect of the RME Approach aided by  Mathematics software on students' mathematical communication ability, (2) there is no significant interaction between the initial mathematical knowledge and the learning approach to students' mathematical communication ability, (3) the students' completion process in solving  mathematical communication problems attain the "good" category.

Abstrak Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemahaman matematis siswa SMP pada materi sistem persamaan linear dua variabel (SPLDV).  Hal ini didasarikarena masih banyak siswa yang kurang memahami konsep SPLDV sehingga siswa merasa kesulitan dalam memecahkanmasalah matematis. Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek dalam penelitian ini adalah siswa SMP.Teknik pengumpulan data menggunakan teknik tes berupa soal uraian yang berjumlah 4 soal dan tiap soal mewakili masing – masing indikator kemampuan pemahaman matematis. Hasil penelitian menunjukkan bahwa (1) Kemampuan pemahaman matematis pada indikator menyatakan ulang sebuah konsep, secara keseluruhan siswa dapat menjawab dengan benar sehingga mencapai tingkat pemahaman yang baik (2) Kemampuan pemahaman matematis pada indikatormengaplikasikan konsep atau algoritma terhadap penyelesaian masalah, siswa dapat membentuk model matematika, kemudian melakukan perhitungan, namun adakesalahan dimana siswa belum mampumenginterpretasikan masalah yang di berikan dengan tepat. Kata kunci: kemampuan pemahaman matematis, siswa SMP, SPLDV.     Abstract This study aims to describe the ability of mathematical understanding of junior high school students in the material system of two variable linear equations (SPLDV). This is based on the fact that there are still many students who do not understand the concept of SPLDV so students feel difficulties in solving mathematical problems. This research is a qualitative descriptive study. The subjects in this study were junior high school students. The data collection technique uses a test technique in the from of a description question which amounts to 4 questions and each questions represent each indicator of mathematical understanding. The result showed that (1) the ability of mathematical understanding on the indicator restated a concept, as a whole students could answer correctly so that they reached a good level of understanding (2) the ability of mathematical understanding of indicators applying concepts or algorithms to problem solving, students could form models mathematics, then do calculations, but there are errors where students have not been able to interpret the problem given correctly.

Attitudes Towards Learning

This experimental research focuses on improving Junior High School students’ mathematical communication ability through the implementation of teaching math using reciprocal teaching method. The low level of students’ mathematical communication ability has been one of the underpinning reasons why this research was carried out in the first place. The aim of this research is to investigate students who are taught using reciprocal teaching methods show better improvement on their mathematical communication ability compared to those who are taught using conventional methods. In addition to that, this research is also interested in understanding students’ attitudes towards learning math using reciprocal teaching method. The research population is all students of SMP Negeri 4 Cimahi, grade VII. The treated group is from class VII B while the controlled group is from class VII H. Both of the groups were chosen randomly. Based on this analysis, it could be concluded that 1) students’ who were taught using reciprocal teaching method showed higher improvement on their mathematical communication ability compared to students who were taught using conventional methods, and 2) almost all students demonstrated positive attitudes towards learning math when they were taught using reciprocal teaching method.
