Abstract

The purpose of this study is to describe the students’ algebraic thinking skills and errors in solving algebraic problems on volume of cube material for class VIII of Junior High School. The research design used was in a form of the descriptive qualitative research method. This study captured the students’ algebraic thinking skill on two indicators, namely the students’ ability to represent problems in the relationship between variables and the students’ ability to perform operations on algebraic form. Based on the result of the categorization, three students from the high-level category were chosen as the subjects of this study. In depth interviews were given to the subjects of the study in order to explore the answers that they provide on the mathematic problems given. The findings revealed that the students with high-level of algebraic thinking skills could solve mathematics problem in algebraic form correctly especially in transformational activities. It was indicated by the students’ ability to provide a solution for algebraic equation problems. Meanwhile, the students’ error in solving the mathematical problems in a form of build-cube space was due to the students’ inaccuracy in writing the final results on the answer sheets for the algebraic thinking ability test. Overall, the students encountered several types of errors, those were the error in the procedural and technical/calculated on comparisons, the error in witing mathematical units, and lastly the error in substituting variables

Abstract

ABSTRACT The purpose of this study was to describe the algebraic thinking skills of junior high school students who were categorized as high and students' errors in solving algebraic problems on the surface area of ??a cube. This study uses a descriptive research method with a qualitative approach. The subjects of this study were three students from class VIII-3 of SMP Negeri 2 Pancalang who were categorized as high level. The instrument in this study is the researcher himself, using an algebraic thinking ability test to measure algebraic thinking skills and interviews to describe the results of the interview. The results of this study indicate that the algebraic thinking of students with high-level categories in solving mathematical problems with the surface area of ??a cube consists of generational, transformational, and global meta-levels. Students tend to do better in global and new generational meta-level activities than transformational activities. Keywords: Algebraic Thinking Ability, Cube Surface Area, Student Error. ABSTRAK Tujuan penelitian ini untuk mendeskripsikan kemampuan berpikir aljabar siswa SMP yang berkategori tinggi dan kesalahan siswa dalam menyelesaikan masalah aljabar pada materi luas permukaan bangun kubus. Penelitian ini menggunakan metode penelitian deskriptif dengan pendekatan kualitatif. Subjek dari penelitian ini adalah tiga siswa dari kelas VIII-3 SMP Negeri 2 Pancalang yang berkategori tingkat tinggi. Instrumen dalam penelitian ini yaitu peneliti itu sendiri, dengan menggunakan tes kemampuan berpikir aljabar untuk mengukur kemampuan berpikir aljabar dan wawancara untuk mendeskripsikan hasil wawancara. Hasil penelitian ini menunjukan berpikir aljabar siswa dengan kategori tingkat tinggi dalam memecahkan masalah matematika materi luas permukaan kubus terdiri atas generasional, transformasional dan level-meta global. Siswa cenderung lebih baik dalam aktivitas level-meta global dan generasional baru kemudian aktivitas transformasional. Kata Kunci : Kemampuan Berpikir Aljabar, Luas Permukaan Kubus, Kesalahan Siswa.
