Widiati, Yuni. 2020. Analisis Kemampuan Penalaran Matematis Siswa Ditinjau Dari Persepsi Siswa Terhadap Materi Aljabar Dikelas VII SMP: Tesis, Program Studi Magister Pendidikan Matematika. Pascasarjana Universitas Jambi, Pembimbing I: Dr. Drs. Kamid, M.Si, dan Pembimbing II: Dr. Dra. Evita Anggereini, M.Si.

Kata Kunci: Penalaran Matematis, Persepsi, Aljabar

Penalaran dalam pembelajaran matematika diperlukan dalam setiap penyelesaian soal matematika. Melalui penalaran, siswa diharapkan dapat melihat bahwa matematika merupakan kajian yang masuk akal atau logis. Persepsi yang baik terhadap pembelajaran matematika membuat siswa senang dan antusias mengikuti pembelajaran sehingga akan menunjang kemampuan penalaran matematisnya. Penelitian ini bertujuan untuk mengetahui: (1) Persepsi siswa terhadap pembelajaran matematika pembelajaran matematika di SMP Negeri 1 Kota Jambi; (2) Kemampuan matematis siswa pada materi bentuk aljabar ditinjau dari persepsi siswa di SMP Negeri 1 Kota Jambi; (3) Persepsi positif atau negatif berdampak pada kemampuan penalaran matematis materi bentuk aljabar di SMP Negeri 1 Kota Jambi.
Jenis penelitian yang digunakan adalah penelitian kualitatif deskriptif. Prosedur penelitian ini terdiri tahap persiapan, peneliti melakukan permintaan izin untuk melakukan penelitian, menyusun instrumen penelitian, dan validasi instrumen penelitian yang berupa angket, soal tes dan pedoman wawancara. Lalu tahap pelaksanaan, peneliti memberikan angket persepsi siswa terhadap materi operasi aljabar, menganalisis hasil angket persepsi lalu membagi siswa menjadi kelompok, menentukan subjek penelitian, memberikan soal penalaran matematis kepada subjek penelitian, mengoreksi jawaban siswa, melakukan wawancara. Selanjutnya data yang diperoleh dalam penelitian ini dianalisis sesuai dengan teknik analisis data. Subjek penelitian ini adalah siswa yang dikelompokkan berdasarkan persepsi positif dan persepsi negative.
Dari hasil penelitian dapat diketahui bahwa persepsi siswa terhadap materi operasi aljabar di kelas VIII SMP Negeri 1 Kota Jambi ialah sebanyak 5 siswa (23,81%) menyatakan sangat positif, 4 siswa (19,04%) menyatakan positif, 10 siswa (47,62%) menyatakan negatif, dan 2 siswa (9,53%) menyatakan sangat negatif. Maka persepsi siswa terhadap materi operasi aljabar dinyatakan negatif lebih dominan, karena frekuensi terbanyak berada pada kategori negatif, yaitu sebanyak 10 siswa. Kemampuan penalaran matematis siswa pada kelompok persepsi sangat positif dan positif termasuk kedalam kemampuan penalaran matematis deduktif sedangkan kelompok penalaran matematis negative dan sangat negative termasuk kedalam kemampuan penalaran matematis pra deduktif.


ABSTRACT

Widiati, Yuni. 2020. Analysis of Students 'Mathematical Reasoning Ability Judging from Students' Perceptions of Algebra Materials in Class VII Middle School: Thesis, Mathematics Education Masters Study Program. Postgraduate of Jambi University, Advisor I: Dr. Drs. Kamid, M.Sc, and Supervisor II: Dr. Dra. Evita Anggereini, M.Sc.

Keywords: Mathematical Reasoning, Perception, Algebra

This study aims to determine: (1) students' perceptions of mathematics learning in mathematics learning at SMP Negeri 1 Jambi City; (2) Mathematical ability of students in algebraic form material in terms of students' perceptions in SMP Negeri 1 Jambi City; (3) Positive or negative perception affects the mathematical reasoning ability of algebraic form material in SMP Negeri 1 Jambi City.
The type of research used is descriptive qualitative research. The procedure of this research consisted of the preparatory stage, the researcher made a request for permission to conduct research, compiled research instruments, and validated the research instruments in the form of questionnaires, test questions and interview guidelines. Then the implementation phase, the researcher gave questionnaire students 'perceptions of algebraic operating material, analyzed the results of the perception questionnaire then divided students into groups, determined the research subjects, gave mathematical reasoning questions to the research subjects, corrected students' answers, conducted interviews. Furthermore the data obtained in this study were analyzed according to data analysis techniques. The subjects of this study were students who were grouped based on positive perceptions and negative perceptions.
From the results of this study it can be seen that students' perceptions of algebraic operating material in class VIII of SMP Negeri 1 Jambi City were 5 students (23.81%) stated very positive, 4 students (19.04%) stated positive, 10 students (47, 62%) stated negative, and 2 students (9.53%) stated very negative. Then the students' perception of algebraic operations material is stated to be negative more dominant, because the highest frequency is in the negative category, which is 10 students. Mathematical reasoning ability of students in the very positive and positive perception group includes the deductive mathematical reasoning ability while the negative and very negative mathematical reasoning group belongs to the pre-deductive mathematical reasoning ability.
