Abstract
This study aims to provide description of mathematical representation ability of Pekanbaru Junior High School students based on the answers to assemblage questions. The research method Decriptive method in the form of a survey was used in this research. The research subject are 25 students of class VII. The object of research is the ability of students' mathematical representation on the assemblage material. The data analysis technique uses deductive methods by collecting data, processing data, presenting data and also analyzing data with the help of experts and theories from a literature review. Data was collected by measuring written tests about mathematical representation abilities. Consists of 6 assemblage of essay questions with moderate criteria. Through the validity test, valid results were obtained with moderate and high criteria and had moderately correlated reliability with good criteria. The results of the data test and analysis concluded that students' mathematical representation abilities applied to assemblage material had 91% visual representation skills using diagrams, 76% representation skills using mathematical expressions, and 51% mathematical representation skills using words.
Highlights
Material delivery in the field of learning studies has a role in human life, including mathematics
An understanding of students will be built on the ability to understand and look for relationships between ideas that develop in mathematics and phenomena that occur around students' lives (Fatqurhohman, 2016)
The result of the research is the stage that has the goal of knowing the level of distance in the ability to perform mathematical representations on students in the assemblage material
Summary
Material delivery in the field of learning studies has a role in human life, including mathematics. The role of mathematics is to connect science to other fields of study. Seeing the role and urgency is quite large in mathematics studies, there is a reason for this field of study to be designated as a mandatory field of study at all levels of education (Sanjaya et al, 2018). The learning material contained in the field of mathematics has connection to other fields of study seen from the use of concepts. Brunner gives an opinion that the best method that can be implemented for the development of student's understanding of learning concepts and propositions in mathematics is the use of representations The development of students' understanding of concepts can be trained through learning in the field of mathematics study. An understanding of students will be built on the ability to understand and look for relationships between ideas that develop in mathematics and phenomena that occur around students' lives (Fatqurhohman, 2016)
