Analysis of Students Mathematical Representation and Connection on Analytical Geometry Subject

Abstract

The importance ability of mathematical representation and connection to owned by the student really help students in understanding the mathematical concepts in the form of pictures, symbols, and the written word. The use of mathematical representation and the correct connection by students will help students make mathematical ideas more concrete and can connect a concept to another concept, so that students can develop a view of mathematics as a whole integration. This research aims to describe and analyze the ability of representation and mathematical connection on the topics of analytical geometry. The research method was descriptive with the subject as much as 22 mathematics students. Data collected through tests and interviews. The results show that the average ability of representation is 46.00; the average mathematical connection ability is 36.77. This means both the abilities still belongs to low, particularly for the ability of mathematical connection. AbstrakPentingnya kemampuan representasi dan koneksi matematis untuk dimiliki oleh mahasiswa sangat membantu mahasiswa dalam memahami konsep matematis berupa gambar, simbol, dan kata-kata tertulis. Penggunaan representasi dan koneksi matematis yang benar oleh mahasiswa akan membantu mahasiswa menjadikan gagasan-gagasan matematis lebih konkrit dan dapat menghubungkan suatu konsep ke konsep yang lain, sehingga mahasiswa dapat mengembangkan pandangan matematika sebagai integrasi yang utuh. Penelitian ini bertujuan untuk mendeskripsikan dan menganalisis kemampuan representasi dan koneksi matematis mahasiswa calon guru matematika pada matei geometri analitik. Metode penelitian adalah penelitian deskriptif dengan subjek mahasiswa calon guru matematika sebanyak 22 mahasiswa. Teknik pengumpulan data menggunakan tes dan wawancara. Hasil menunjukkan bahwa rata-rata kemampuan representasi sebesar 46,00; rata-rata kemampuan koneksi matematis sebesar 36,77. Ini berarti kedua kemampuan tersebut masih tergolong rendah, terutama untuk kemampuan koneksi matematis.

Mathematical Representation of Grade 7 Students in Set Theory Topics Through Problem-Based Learning

“…However, despite the crucial mathematical representation as to the goal learning of mathematics, students still lack this capability. Previous studies said that many students still have a low level of mathematical representation (Hernawati, 2016;Hutagoal, 2013;Noto, Hartono, & Sundawan, 2016).…”

Design of Mathematics Student Worksheet based on Discovery Learning Approach to Improving Mathematical Representation Ability Students of Grade VII Junior High School in Indonesia

“…One of the contexts tested in the PISA problem is the ability of representation, meaning that the ability of student representation in Indonesia is still low. The results of other studies indicate the ability of mathematical representation of prospective teachers is still relatively low [7]. Student performance and student representation test at one of the junior high schools in North Sumatra fall into the low category [11].…”

“…Using visual representation can help in understanding the problem and can improve students' mathematical reasoning abilities [6]. The correct use of mathematical representations and connections will make the accurate notion that is being learned more concretely and can connect between concepts, to view mathematics as a complete integration [7]. Student representation influences their way of forming generalizations and justifying what has been done [8].…”

The Correlation Between Cognitive Style and Students’ Learning Achievement on Geometry Subject

“…Students are still having trouble doing the analytic geometry. The results of Noto, Hartono, & Sundawan show that the ability of representation and mathematical connections of students in the course of analytic geometry (Noto, Hartono, & Sundawan, 2016).…”
