This study aims to generate a clear and comprehensive description of the students’ competence in the mathematical modeling courses after the lecturers are based on the design task. The students’ 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 main principle in today's mathematics learning was to improve and prepare learning activities that gave benefit to students who aim to move from teaching mathematics to learning mathematics and the solution was translate again as a real-world problem solution. This study aims to generate learning path that used mathematical modeling so that it can help students understand the material sequence. The research method used design research. Hypotetical Learning Trajectory in design research played an important role as design and research instrument. HLT was designed in the initial design phase and tested in grade IX students (ie, 6 students on pilot experiment and 35 students in teaching experiment) SMA Negeri 4 Pagaralam. In retrosvectife analysis, actual learning during teaching experiments compared with HLT has been designed to show that with the context of the model of business development and using mathematical modeling can help students in understanding the learning sequence.

This research is a design research that aims to generate the learning trajectory of students in linear equations with one variable using a balancing tool. Resolve problem related to linear equations with one variable is one of the basic competencies in the high school curriculum for grade 7. But in fact, many students are having difficulty in solving the story problem on linear equations with one variable, so that causing students to make mistakes. Mathematical learning should begin with the introduction of contextual problems. By posing contextual problems, learners are gradually guided to master mathematical concepts. One approach to mathematics learning in accordance with that is the Indonesian Realistic Mathematics Education (PMRI). Researchers designed the hypotetical learning trajectory to be used as guidelines for teachers during the learning process. The appropriate starting point for studying the concept of linear equations with one variable is about balance activity. The contextual problem chosen by researcher is about using a balancing tool. The results showed that the learning of linear equations with one variable using PMRI can help students develop from the informal to the formal stage of mathematics and can be used as alternatives in learning.

By modeling learning students enjoy learning and doing mathematics in new ways. This study aimed firsly to produce senior high school mathematics modeling tasks, lesson plan, and student worksheet for valid mathematical learning; secondly, to produce senior high school mathematics modeling, lesson plan, and student worksheet for practical mathematics learning; lastly, to produce senior high school mathematics modeling tasks, lesson plan, and student worksheet for potentially effective mathematics learning. This study used method of development research that consisting of 3 steps, i.e., analysis, design, and evaluation. In the analysis stage, researcher did student analysis, curriculum, and mathematical modeling. Second stage are to design and product. Finally, researchers applied a design of formative evaluation consists of self-evaluation, one-to-one, experts review, small group, and field test. Based on experts review, one-to-one, small groups, and field test were obtained valid, practical, and potentially effective, i.e. mathematical modeling tasks, lesson plan, student worksheet to teach mathematical modeling in senior high school and Mathematical modeling tasks and student worksheets to learn mathematical modeling in senior high school.

The purpose of this research is to know how Naive Geometry method can support students' understanding about the concept of solving quadratic equations. In this article we will discussÃ‚Â one activities of the four activities we developed. This activity focused on how students linking the Naive Geometry method with the solving of the quadratic equation especially on how student bring geometric solution into algebraic form. This research was conducted in SMPÃ‚Â Negeri 1 Palembang. Design research was chosen as method used in this research that have three main phases. The results of this research showed that manipulating and reshaping theÃ‚Â rectangle into square could stimulate students to acquire the idea of solving quadratic equations using completing perfect square method. In the end of the meeting, students are also guided to reinvent the general formula to solve quadratic equations.Keywords: Quadratic Equations, Design Research, Naive Geometry, PMRI

This research is aimed to determine the role of Indonesian folklore context namely the Legend of Kemaro Island in supporting average learning on 6-grade students with Pendidikan Matematika RealistikIndonesia (PMRI) approach. The method used is design research that contains three stages namely preliminary design, teaching experiment, and retrospective analysis. Results from the research show that Indonesian folklore context can support students to develop their knowledge in the concept of average. Strategy and model (emergent modeling) that students discover, describe and discuss the construction or contribution shows how students can use to help their initial understanding of the concept of average.
