Abstract

Analytical ability is the competence of connecting information that is broken down into whole parts in determining solutions. Good geometry teaching must be in accordance with the individual's thinking stages. The purpose of this study is to produce a study on the description of students' analytical abilities in solving Euclid's geometry problems based on Van Hiele's theory. The subjects in this study were 20 students of the Mathematics Education study program at the Soe Institute of Education who accessed the Euclid geometry course. The data collection technique used was an interview with 6 (six) students. The data analysis technique follows the Miles and Huberman model. Data validity testing is carried out by triangulating sources. The results of this study indicate that (1) at the introduction stage, students already understand the shape of the geometric shapes; (2) at the analysis stage, students are able to identify the properties of the geometric shapes; (3) at the sequencing stage, students are able to compile a definition of a geometric figure based on the properties between figures and provide an explanation of the relationships between figures; (4) at the deduction stage, students are able to use conjectures from geometric figures correctly and (5) at the accuracy stage, students are able to solve problems with solutions in terms of using conjectures or theorems correctly and are able to provide conclusions. There are also students who do not reach all five stages of thinking completely due to their low understanding of geometry

Abstract

Literasi matematis merupakan kemampuan seseorang untuk merumuskan, menerapkan dan menafsirkan matematika dalam berbagai konteks, termasuk kemampuan melakukan penalaran secara matematis, menggunakan konsep, prosedur, fakta dan alat bantu matematika untuk mendeskripsikan suatu fenomena atau kejadian. Tujuan penelitian ini adalah untuk menghasilkan kajian tentang kemampuan literasi matematis siswa dalam menyelesaikan soal PISA konten change and relationship. Penelitian dilakukan di SMA Efata Soe dengan subjek penelitian adalah siswa kelas X Mia 1 sebanyak 30 siswa. Penelitian ini menggunakan pendekatan kualitatif dengan teknik pengumpulan data berupa tes, observasi dan wawancara. Teknik analisis data menggunakan model Miles dan Huberman. Hasil penelitian menunjukkan hanya sebagian kecil siswa yang mampu mencapai semua indikator literasi matematis yaitu mengidentifikasi aspek-aspek matematika, mengubah ke dalam model matematika, merancang model untuk menemukan solusi dan menafsirkan hasil matematika ke dalam konteks dunia nyata. Sebagian besar siswa hanya mampu menyelesaikan soal sampai pada tahap membuat model, menerapkan rancangan model dan masih kesulitan dalam menemukan solusi yang tepat dan menafsirkan ke dalam konteks dunia nyata. Penyebab kesulitan tersebut karena dalam pembelajaran siswa kurang dibiasakan mengerjakan soal-soal latihan maupun tugas berkarakteristik PISA yang membutuhkan  kemampuan literasi matematis dalam penyelesaiannya.
