Abstract

AbstractPenelitian ini bertujuan untuk mengetahui kemampuan berpikir aljabar siswa kelas VIII dalam menyelesaikan soal cerita pada materi bangun ruang sisi datar ditinjau berdasarkan kemampuan matematika di MTs Negeri 2 Pontianak. Metode penelitian yang digunakan adalah deskriptif dalam bentuk studi kasus. Subjek penelitian yaitu 34 siswa. Teknik pengumpulan data yang digunakan yaitu tes dan non tes (wawancara). Secara umum dapat disimpulkan bahwakemampuan berpikir aljabar siswa kelas VIII dalam menyelesaikan soal cerita materi bangun ruang sisi datar ditinjau berdasarkan kemampuan matematika di MTs Negeri 2 Pontianak adalah siswa hanya mampu berada pada tahap indikator transformasi, tetapi siswa masih belum mampu menuliskan ekspresi (bentuk aljabar) dengan benar, belum mampu menuliskan model matematika dan dalam menyelesaikan masalah tidak menuliskan aturan yang digunakan serta tidak menulis kesimpulan. Kata Kunci: Kemampuan Berpikir Aljabar, Menyelesaikan Soal Cerita, Kemampuan Matematika.

Abstract

 AbstractThis reseach aims to determine the student’s conceptual understanding on the material of space build was viewed from the analogy reasoning ability in class IX SMP Negeri 1 Sungai Raya. Method used was descriptive in form case study. The subjects were 34 students. Data collector in this research use student answer sheet and interview result. The results showed that students with high, medium and low analogy reasoning ability level tend to had medium conceptual understanding categories. In general it can be concluded that the conceptual understanding of the students of class IX of SMP Negeri 1 Sungai Raya varies for each level of analogy reasoning ability. Students with high analogy reasoning ability level do not always have high conceptual categories of understanding, students with medium analogy reasoning ability levels do not always have medium conceptual understanding categories, and students with low analogy reasoning ability level do not always have low conceptual understanding categories. Keywords: Conceptual Understanding, Analogy reasoning ability, Space Build.

Abstract

This study aims to determine the conceptual understanding of students at SMP Negeri 16 Pontianak regarding the material on Systems of Linear Equations in Two Variables (SPLDV) which depends on their mathematical abilities. In this research, nine class IX C students were used as a source of descriptive data. The data collected in this research came from daily tests carried out by students to determine their ability level. The results of the research show that the five indicators of conceptual understanding used indicate that students' conceptual understanding is classified as moderate. These indicators are as follows: (1) students' conceptual understanding of re-explaining SPLDV concepts is in the medium category, (2) students' conceptual understanding of determining examples and non-examples of SPLDV material is in the low category, (3) students' conceptual understanding of grouping objects according to their characteristics are included in the low category, (4) The high category has a conceptual understanding of indicators of use, utilization and selection of procedures in SPLDV material, (5) the medium category has a conceptual understanding of usage indicators and the relationship between models, diagrams and concept representations different in SPLDV material.
