Publisher : Department of Doctoral Program on Mathematics Education, Sriwijaya University

Several researches showed that students had difficulty in understanding the concept of Least Common Multiple (LCM) in Elementary School. This underlies the researcher to design a learning of LCM using storytelling, Legend Putri Dayang Merindu (LPDM), which contains situational problem related to LCM. The purposes of this study are to know the role of LPDM in supporting students' ability to understand LCM concept and to generate a student learning trajectory in learning of LCM using LPDM. This research uses methodology of design research consists of three steps (i.e. preliminary design, teaching experiment andÂ retrospective analysis), and the learning approach of realistic mathematics education, labeled by PMRI in Indonesia. From the research result conducted in MIN 1 Palembang can be concluded that the learning of LCM using LPDM has role in supporting students' ability to understand LCM concept. Therefore, student learning trajectory to understanding LCM concept is started from solving of situational problems based on LPDM until formal solution of LCM. In this case, there are three stages that students through (i.e. understanding concept of multiple, common multiple and LCM) using various strategies in the level situational, model of, model for and formal.

Abstract. This study aims to develop teaching material for algebra operations for grade of junior high school using the approach of Indonesian Realistic Mathematics Education and determine its potential effects on learning outcomes. This study uses the type of formative research methods development research. Step by step studies include preliminary stages (preparation and designing) and the formative stages of evaluation (self-evaluation, revision, one to one, experts review, revision, small group, revision, and field test, revision). Data was collected by walk through, documentation, and test competencies. The result validates the expert views that teaching material of algebra operations for seventh grade of junior high school is an valid and practical that can be used in fields trials. The trials of teaching materials were conducted in junior high school 6 of Sekayu, Musi Banyuasin at 7.1 by 30 students. Competency test result show that 77% of students achieved minimum qualifications in which 47% with excellent qualifications, 40% good qualified, 6,7% sufficient qualification, and 6,7% lesws qualifications. The results of students answer analysis show that students are able to understand the problem, determine the variables in a problem, and expressed in algebraic form. However, students are not careful when completing subtraction algebraic expression using parentheses. Keywords: algebra expression, PMRI, teaching materials.

This study aims to generate a clear and comprehensive description of the studentsâ€™ competence in the mathematical modeling courses after the lecturers are based on the design task. The studentsâ€™ competence that will be measured in this research is the competence in constructing mathematical modeling that has been made. In this paper, we will deeply discuss for the competence in constructing mathematical modeling task and validating it. The method used is descriptive qualitative and the subject of this study were 23 students of the 2017/2018 academic year who took mathematics modeling courses. This research starts from the planning stage, namely the analysis of the study of mathematical modeling material, design and validation of research instruments. Furthermore, the implementation phase is taking observation data, interviews and field notes during lectures based on problem development. The last stage of the research is data analysis. The data collection techniques in this study were in the form of observations, interviews, and field notes. The results of this study were obtained descriptions of student competencies in constructing mathematical modeling problems and found misunderstanding of students in interpreting assumptions and variables in mathematical modeling.

The process of thinking in formulating a mathematical model requires cognitive processes. In learning mathematics, one of the factors that influence mathematics ability is gender differences. This research explores and provides an overview of the cognitive processes, especially using the representational form in mathematical modeling regarding gender differences. The type of research used is descriptive exploratory with a qualitative approach. The research subjects were 36 pre-service teachers in the mathematics education study program, consists of 18 males and 18 females. The instruments were a written test and an interview guide sheet. The result shows that males get higher percentages than females to answer the representational problem correctly. In conclusion, both males and females solve the graph problem using representative form through three components of the cognitive process. The first and second component, namely knowing and applying, shows the same behavior: retrieving the information from the mathematical problem and displaying the information into the graph. For the third component, reasoning also offers the same behavior because the truth of the graph that justifies refers to the mathematical properties. The study implies that it might be the same treatment for males and females to improve representational form regarding the components of cognitive process, namely, knowing, applying, and reasoning.
