Sari, Lutviana Kumala, 2026. Analisis Kemampuan Representasi Matematis
Ditinjau dari Tingkat Self-confidence Siswa Kelas X SMAN 3 Ponorogo. Skripsi. Program Studi Tadris Matematika, Fakultas Tarbiyah dan Ilmu Keguruan, UIN Kiai Ageng Muhammad Besari Ponorogo. Pembimbing: Kurnia Hidayati, M.Pd.
Kata kunci: representasi matematis, self-confidence, trigonometri, SMA
Kemampuan representasi matematis dalam pembelajaran matematika dapat memfasilitasi siswa dalam memahami konsep dan juga menguasai proses berpikir matematis. Kemampuan representasi matematis sendiri yaitu kemampuan menyajikan solusi matematika dalam berbagai bentuk seperti simbol, gambar, dan verbal. Kemampuan representasi matematis dapat dipengaruhi oleh beberapa faktor. Salah satunya faktor afektif yaitu self-confidence siswa. Self-confidence merupakan keyakinan individu mengenai kemampuannya dalam menyelesaikan tugas atau permasalahan.
Penelitian ini bertujuan untuk mendeskripsikan kemampuan representasi matematis ditinjau dari tingkat self-confidence siswa kelas X SMAN 3 Ponorogo. Fokus penelitian ini tentang tingkat self-confidence siswa, kemampuan matematis siswa, dan materi perbandingan trigonometri pada segitiga siku-siku.
Peneliti ini menggunakan pendekatan kualitatif dengan metode deskriptif. Teknik pengumpulan data dilakukan dengan pengisian angket, tes dan wawancara. Responden angket self-confidence penelitian ini siswa kelas X F. Informan tes dan wawancara perwakilan 2 siswa dari tingkat self-confidence. Analisi data dilakukan dengan teknik reduksi data, penyajian data, dan penarikan kesimpulan berdasarkan model Miles dan Huberman.
Hasil penelitian ini menunjukkan bahwa siswa yang memiliki self-confidence tinggi mampu merepresentasikan dengan baik semua indikatornya. Siswa yang memiliki self-confidence sedang hanya bisa merepresentasikan mengenai indikator ekspresi matematis. Siswa yang memiliki self-confidence rendah belum bisa merepresentasi seluruh indikator.

Sari, Lutviana Kumala, 2026. Analysis of Mathematical Representation Ability
Viewed from the Self-confidence Level of Grade 10 Students of SMAN 3 Ponorogo. Thesis. Mathematics Education Study Program, Faculty of Tarbiyah and Teacher Training, UIN Kiai Ageng Muhammad Besari Ponorogo. Supervisor: Kurnia Hidayati, M.Pd.
Keywords: mathematical representation, self-confidence, trigonometry, high school.
Mathematical representation skills in mathematics learning can facilitate students' understanding of concepts and mastery of mathematical thinking processes. Mathematical representation skills themselves are the ability to present mathematical solutions in various forms such as symbols, images, and verbally. Mathematical representation skills can be influenced by several factors. One of these affective factors is student self-confidence. Self-confidence is an individual's belief in their ability to complete a task or problem.
This study aims to describe the mathematical representation ability viewed from the self-confidence level of grade X students of SMAN 3 Ponorogo. The focus of this study is on the level of student self-confidence, student mathematical ability, and trigonometric comparison material in right triangles.
This researcher used a qualitative approach with a descriptive method. Data collection techniques were carried out by filling out questionnaires, tests, and interviews. The respondents of this research self-confidence questionnaire were students of class X F. The informants for the tests and interviews were 2 representative students from the self-confidence level. Data analysis was carried out using data reduction techniques, data presentation, and drawing conclusions based on the Miles and Huberman model.
The results of this study indicate that students with high self-confidence were able to represent all indicators well. Students with moderate self-confidence could only represent indicators of mathematical expressions. Students with low self-confidence were unable to represent all indicators.
