<p><strong>Abstract:</strong> Mathematical representation is the way of communicating mathematical ideas and problems solutions. Communicating mathematical ideas requires external representation in the form of actions, verbal, symbolic, visual and real objects. This study aims to describe the form of representation of Deaf Students in solving mathematical story problems. The research was conducted by giving types of text questions as well as text and image questions to three DS at Banyuwangi State of Special Need High School. The results of student work analysis found that there are two types of mathematical representations that appear in solving story problems, namely verbal representation indicated by writing words, numbers, letters, sentences and oral and representation of mathematical expressions in the form of symbols and numbers. DS are able to representing, make mathematical symbols, explain in writing or sign language what they think are.</p><strong>Abstrak:</strong><em> </em>Representasi matematis adalah cara mengomunikasikan ide-ide matematis maupun solusi permasalahan.

AbstractThe mathematical representation ability referred to in this study is the ability to express mathematical ideas or ideas to solve a problem with various mathematical representations of visual forms (pictures) and verbal forms (writing).This type of research is descriptive with a qualitative approach which aims to describe systematically the ability of visual mathematical representations and the ability of verbal mathematical representations.The data collection technique in this study was carried out using essay. Test questions were given to student an grade VIII A at SMP Negeri 1 Mandor, where there were three groups, namely the upper, middle, and lower group. Students who will be interviewed are selected based on the representation ability test scores where only two students will represent for each group.The results showed that the ability of visual mathematical representation when given verbal form questions to answer indicators using pictures was in the percentage of students' average score 66.67% and the ability of verbal mathematical representation if given visual questions, for the answer indicator using words is in the percentage of the student's average score of 33.33%. Students still have difficulty with verbal representation if given a visual form. Keywords: visual representation, verbal representation and trangle material

The inclusion of representation as a standard component of the process in Principles and Standards for School Mathematics in addition to problem solving, reasoning, communication, and connection skills is reasonable because to think mathematics and communicate mathematical ideas one needs to represent it in various forms of mathematical representation. Besides, it can not be denied that objects in mathematics are all abstract so that to learn and understand abstract ideas that would require a representation. Representation occurs through two stages, namely internal representation and external representation. Examples of external representations include: verbal, drawing and concrete objects. Thinking of a mathematical idea that allows a person's mind to work on the basis of the idea is an internal representation. A mathematical problem posed to the student and the student can solve it, so at least the student understands the problem, so that students can plan the settlement, perform the calculations appropriately, and be able to check or review what has been processed correctly. The smoothness and flexibility of students in constructing representations is largely lacking. This is evident from at least the structured algebraic form, as well as the way in which most representations are found very little. In addition, the quantitative scores of respondents in the representation are still in the low category with a moderate tendency.

In the November 1970 issue of the Arithmetic Teacher there appeared my article, “Mathematical Systems and Their Relationship to the Real World.” One point I made is that mathematics provides us with a vast array of symbols and concepts to use in solving real-life problems. When we use mathematics to solve a real problem, we make certa in mental associations between mathematical symbols and real objects. I suggested that arguments sometimes arise because two persons may make different associations, mathematical symbols to real objects, and each thinks his associations are correct while the other person's are incorrect.

Everyday Experiences

Children's literature can be a springboard for conversations about mathematical concepts. Austin (1998) suggests that good children's literature with a mathematical theme provides a context for both exploring and extending mathematics problems embedded in stories. In the context of discussing a story, children connect their everyday experiences with mathematics and have opportunities to make conjectures about quantities, equalities, or other mathematical ideas; negotiate their understanding of mathematical concepts; and verbalize their thinking. Children's books that prompt mathematical conversations also lead to rich, dynamic communication in the mathematics classroom and develop the use of mathematical symbols in the context of communicating. The National Council of Teachers of Mathematics (1989) emphasizes the importance of communication in helping children both construct mathematical knowledge and link their informal notions with the abstract symbols used to express mathematical ideas.

This article aims to determine the extent of the mathematical connection ability of the linear equations system of two variables in terms of the connection representation and procedural connections. This type of research uses a qualitative approach. This study's subjects were the students of class X MIPA 1 MA P2K Al Hidayah Lajukidul, which numbered 24 students. However, only six subjects were taken based on the level of mathematical connection ability high, medium, and low that had been selected by mathematics subject teachers based on students' ability to solve math story problems. The research instrument consisted of tests and interview questions. Data analysis techniques using the model of Miles and Huberman include data reduction, data presentation, and concluding. The study results showed that in question no. 1, all research subjects can represent connections and procedural connections, students can write mathematical symbols and answer questions using formulas correctly. In problem no.2, only the subject of high mathematical connection ability can connect representation and procedural connections. The other subject is not quite right in writing mathematical symbols. In question no.3, only subjects with low mathematical connection ability do not have representation and procedural connection skills; students only write what is known but is incomplete. In conclusion, the two-variable linear equation system's mathematical connection ability in terms of the connection representation and procedural connections are not evenly distributed.   Artikel ini bertujuan untuk mengetahui sejauhmana kemampuan koneksi matematis materi sistem persamaan linear dua variabel ditinjau dari koneksi representasi dan koneksi prosedural.

Reading literacy activities are currently being held by all levels of education. Literacy activities have a positive effect on students in understanding information. The ability to understand information can be realized through mathematical representation, which is one of the main elements in mathematical understanding. This research can help educators in mapping the mathematical representation ability based on the reading interest of students. The purpose of this research is to identify which indicators can be mastered by students who have reading interests at high, medium, and low levels. This research is qualitative. The research subjects were students of the Mathematics Education Department of Ivet University. The data collection procedures used were scale, test, and interview. The instruments of this study were the reading interest scale, mathematical representation ability test, and interview sheets. The data analysis technique of this study adopted data analysis techniques from Miles and Huberman. The conclusions of this study are (1) students with high and medium reading levels have the ability to represent mathematical representations to model and interpret physical, social, and mathematical phenomena; have the ability of mathematical representations to create and use representations to communicate mathematical ideas or concepts; have the ability of mathematical representations in selecting, applying, and translating mathematical representations to solve problems, (2) students with a low reading level have lacked on the ability of mathematical representations to use representations to model and interpret physical, social, and mathematical phenomena, thus it caused them couldn’t mastering the ability of mathematical representations to create and use representations to communicate mathematical ideas or concepts and the ability of mathematical representations to select, apply, and translate mathematical representations to solve problems.
