Communicating ideas using language and mathematical notation is even more practical, systematic, and efficient. Recognizing the importance of mathematical communication skills then as a prospective educator should seek learning that can provide opportunities and encourage students to trained the ability of mathematical communication. Indicator of mathematical communication ability in this research include grammatical ability (K1) and sociolinguistic ability (K2). The subject of high school mathematics curriculum is a compulsory course that must be taken, because it will be discussed about the subject matter of school math and various models. One of the learning model that meets the indicator of mathematical communication ability is IDEAL Problem Solving model.</p><p>This study aims to improve the ability of mathematical communication in grammatical and sociolinguistic aspects. The type of research used is classroom action research based on Stephen Kemmi and Robin Mc Taggart models. From the result of the research, it is found that the application of IDEAL Problem Solving model of high school mathematics curriculum can improve mathematical communication ability in grammatical (K1) and sociolinguistic (K2) aspect. The percentage of grammatical aspect (K1) increased from 78% to 89% and sociolinguistic aspects (K2) increased from 81% to 89%.</p>2017-11-23T09:33:08+07:00Copyright (c) 2017 Jurnal Didaktik Matematikahttp://jurnal.unsyiah.ac.id/DM/article/view/8863Analisis Peningkatan Kemampuan Representasi Matematis Siswa SMA Ditinjau dari Perbedaan Gender2018-01-10T05:52:07+07:00Izwita Dewidewi_lubis62@yahoo.co.idSahat Saragihdewi_lubis62@yahoo.co.idDewi Khairanidewi_lubis62@yahoo.co.id<p><em>Mathematical representation is one of the mathematical higher order thinking skills, as a tool or way of thinking in communicating mathematical ideas. Referring to a research about the inconsistency of a mathematical communication profile involving gender differences and the phenomenon of more female students than men right now, there appears to be an allegation that there is a connection between gender differences and students mathematical representation. The purpose of this study is to analyze the improvement of students' mathematical representation capability in terms of gender differences. Subjects in this research were students of class X of High School in Medan, Indonesia, consisting of 13 men and 19 women. The research instrument is a mathematical representation test consisting of 4 questions. Data analysis to find out how the category of improvement of students’ mathematical representation, using index of N-gain. The results of the research are: (1) the improvement of mathematical representation ability in the lower and middle categories of male students is higher than female students, (2) there is no male students have high category mathematical representation, but there are female students have high category mathematical representation abilities, and (3) the ability of representation to make mathematical models and explain the verbal language of male students is higher than female students. While the representational ability of making tables and drawing female students is higher than male students. The implication of the research is needs to do deeper research to see the relationship of mathematical representation ability with the students' mathematical ability profile.</em></p>2017-10-04T00:00:00+07:00Copyright (c) 2017 Jurnal Didaktik Matematikahttp://jurnal.unsyiah.ac.id/DM/article/view/8384Struktur Lapisan Pemahaman Konsep Turunan Fungsi Mahasiswa Calon Guru Matematika2018-01-10T05:52:07+07:00Viktor Sagalaviktor.sagala@unitomo.ac.id<em>Prospective mathematics teachers should have met the Pirie-Kieren model of understanding indicators, to become professional teachers. The purpose of this research is to describe the layers of understanding structure that is filled by students of mathematics teacher prospectives. The description is based on a model hypothesized by Pirie-Kieren. Research subjects selected from female and male mathematics teacher prospective students have been given the task of understanding the concept of derivative functions and interviewed. Data collected from students’ answers from worksheets before the interview, students’ answers from worksheets during interviews, and interview transcripts. After the data were analyzed qualitatively, the description of the understanding layer structure of two subjects grouped by the original Pirie-Kieren Model was obtained. The subjects of female had met the indicators of primitive knowing, then there are the processes of image doing and image reviewing on the layer structure of image making towards image having, then image seeing and image saying on the layer of image having to property noticing, then there are the processes of property predicting and property recording on the layer of property noticing towards formalizing, then there are the processes of method applying and method justifying on the layer of formalizing towards observing, then there are the processes of future identifying and feature prescribing on the layer of observing towards structuring, and there are the prosesses of theorem conjecturing and theorem proving on the layer of structuring towards inventising.

The use of technology can be an alternative to create an interesting and effective of instructional Media. One of the application programs that teachers can choose is Tarsia Formulators. This formulator is a program designed for math teachers to create puzzles, dominoes, and other forms of activity. This paper discusses examples of the application of puzzles created from tarsia formulators in mathematics learning. Learning activities begin by introducing the form of puzzles to be assembled by the students. The teacher gives an explanation of the rules that apply in this lesson. Teacher guides need to be done to make it easier for students who have difficulty. Furthermore, the teacher displays the correct form of the puzzle in comparison to the student's work and provides an explanation of the answer to the problem presented. The tarsia formulators makes it easy for teachers to create effective and varieties instructional media, so students do not feel bored in classroom learning activities.</em>2017-11-10T00:00:00+07:00Copyright (c) 2018 Jurnal Didaktik Matematika
