Abstract

The purpose of this study was to describe ethnomathematics on Dayak Tabun traditional tools in school mathematics learning. This study uses a qualitative approach, with descriptive research methods. Observation techniques are direct observation and communication techniques, namely interviews with Dayak Tabun community leaders, especially makers, users, and traditional stakeholders. the results of the research obtained are: 1) form, learning context in geometric concepts, namely flat and wake up space; 2) aspects of the motive, the learning context in the geometry concepts, like are two-dimensional, lines, and angles, besides that the algebraic concept is a number pattern in the form of a constant sequence; 3) the way of making, the learning context in the algebraic concept of numbers, namely fractions in dividing the material into two parts, calculating operations especially on natural numbers, sequential numbers through measurement of materials; 4) in terms of the use of tools, the context of calculating operating learning is the tool used in the dance, namely the tapping of movements and elevation angles in trigonometric material, namely the use of a Sangkuh Akai tool. Therefore, ethnomathematics on traditional Dayak Tabun ethnic instruments can be used as the context of school mathematics learning.

Abstract

Scaffolding is assistance provided so students can solve problems or understand concepts that can not be solved independently. When students are considered capable of completing their tasks independently, the assistance is eliminated. In this study, scaffolding was carried out by giving problems about graph theory. Problems given are closed and open contextual problems. The selection of this problem can be seen by students' understanding of graph theory. The results of this study, this problem-based scaffolding can help students who experience difficulties in the problem of graph theory. Students are enthusiastic because through this problem, they can explore and connect blood donation problems and regional tourism with the concept of graph.

Abstract

This study aims to describe students' difficulties in solving numerical patterns in the context of the Toba Batak ethnic culture after the implementation of the Realistics Mathematic Education Approach in the context of the Toba Batak Tribe Culture. Subjects in this study were students of class VIII Junior High School (SMP) totaling 32 people. The data collection tool used in this study is a test that totals ten questions in the form of a description. This type of research is a qualitative descriptive study. Data collection techniques are carried out by tests, observation, interviews, and documentation. Data analysis techniques were carried out by data reduction, data presentation, and concluding. The results showed that students had difficulty determining the sequence of numbers, determining the configuration of a sequence of numbers, determining the arithmetic series, determining the number of n first arithmetic series terms, determining the first term n row geometry, and determine the number of n first terms of the geometry series. The causal factor is that students are not able to distinguish the general formula concept of a sequence and the concept of configuration patterns from a sequence of numbers, operating error calculations and not understanding integer ranks.

Abstract

By looking at the learning result of Lecturer of DIII Mechanical Engineering Department of Harapan Bersama seen the lack of understanding of the students understanding the subject matter of Applied Mathematics. The objective of the research is to produce a mathematics learning device with Think Talk Write model based on Hand On Activity to improve the valid ability of troubleshooting, practical, and effective math problem solving. This research is a development research using 4D model that is modified into 3D consists of defining, designing and developing phases. The types of devices developed are: (1) Syllabus; (2) Semester Study Plan; (3) Modules and (4) Worksheets , and (5) Troubleshooting Test. The subject of this research is the D III students of Mechanical Engineering Department. Independent variables of this research are independence and problem-solving skills, while the dependent variable is the result of Troubleshooting test. Conclusions gained (a) Students achieved mastery individually (scores above 80) as well as classical, (b) The ability of troubleshooting of Applied Mathematics in a class that uses Think Talk Write model devices based on Hand On Activity is better than the ability of class math problem solving with conventional method, (c) The existence of influence of independence character and problem solving skill to troubleshooting ability of subject Applied Mathematics equal to 90%.

Abstract

This study aims to know mathematics preservice teachers? common sense understanding of mathematical literacy. The results will later be used to design a learning program to introduce mathematical literacy to preservice teachers so that they have a better understanding of mathematical literacy. Data were collected by giving questionnaires to one hundred and eight mathematics preservice teachers. The result showed that mathematics preservice teachers? views on mathematical literacy can be categorised into 5 areas: 1) ability that has to do with problems in people?s daily life, 2) communicating using mathematics concepts and properties, 3) interpreting mathematical sentences into everyday language or vice versa, 4) activity related to reading and writing about mathematics, 5)  basic knowledge of mathematics. Preservice teachers agreed that learning mathematics in schools should connect mathematical concepts with real-life problems. They are also ready to increase the mathematical literacy abilities of their future students.
