Abstract

Penelitian ini dilatarbelakangi oleh temuan kesulitan belajar siswa dalam belajar matematika. Tujuan penelitian ini adalah untuk mendiagnosis kesulitan belajar siswa dalam kemampuan pemecahan masalah berdasarkan prosedur Newman dan melaksanakan remedial teaching untuk mengatasi kesulitan belajar siswa. Pembelajaran kooperatif tipe Think Pair Share diajarkan kepada siswa untuk memberikan kemampuan pemecahan masalah. Subjek penelitian adalah sembilan siswa kelas X Mipa 1 di SMA Negeri 1 Petarukan yang diambil 3 siswa pada kelompok atas, tengah, dan bawah. Hasil penelitian ini adalah: 1) kebanyakan letak kesulitan belajar siswa adalah pada tahap memahami (comprehension) dan tranformasi. Untuk kesalahan process skill dan encoding terjadi karena siswa mengalami kesalahan pada tahap sebelumnya. Temuan faktor penyebab kesulitan belajar siswa yaitu 3 siswa mengalami kesulitan belajar bersifat fisiologis, 5 siswa bersifat psikologis, 1 siswa bersifat pedagogis, 6 siswa bersifat sosiologis; 2) remedial teaching berhasil mengatasi kesulitan belajar sebanyak 8 dari 9 siswa atau 89% siswa. Sehingga dapat dikatakan remedial teaching efektif dalam mengatasi kesulitan belajar. This research was motivated by findings of students' learning difficulties in learning mathematics. The purpose of this research was to diagnose students' learning difficulties in problem solving skill based Newman procedures and implement remedial teaching for eclipse students learning difficulties. Cooperative learning Think Pair Share was taught to students to give problem­solving skills. The subjects were nine students class of X science 1 at SHS 1 Petarukan taken three students in the top group, middle, and bottom. The results of this research are: 1) the most mistake of student learning difficulty was at the stage of understanding (comprehension) and transformation. For process skill and encoding errors occur because students had an error in the previous stage. The factors causing of students' learning difficulties were three students had learning difficulties were physiological, 5 students were psychological, one student was pedagogical, 6 students were sociological; 2) remedial teaching successfully eclipse learning difficulties 8 of 9 students or 89% of students. So it can be said that remedial teaching effective to eclipse learning difficulties.

Abstract

Berpikir aljabar merupakan representasi dari aktivitas maupun kemampuan dalam mempelajari aljabar sekolah. Tujuan penelitian ini adalah untuk mengetahui kemampuan berpikir aljabar siswa SMP Kelas VIII. Metode penelitian yang digunakan adalah dengan pendekatan deskriptif kualitatif. Penelitian ini dilakukan dengan memberikan tes kemampuan berpikir aljabar pada siswa. Selanjutnya berdasarkan hasil tes, siswa dikelompokkan berdasarkan kemampuan berpikir aljabar mereka yang terdiri dari kelompok tingkat tinggi, kelompok tingkat sedang, dan kelompok tingkat rendah. Dari masing-masing kelompok tersebut dipilih dua subjek sebagai perwakilan untuk diwawancara lebih lanjut terkait kemampuan berpikir aljabar mereka. Hasil analisis dari penelitian ini menunjukkan bahwa kemampuan generasional, transformasional, dan level-meta global sudah terlihat pada sebagian siswa kelas VIII. Siswa yang termasuk dalam kelompok tingkat tinggi mempunyai kemampuan generasional, transformasional, dan level-meta global yang cenderung tinggi. Sedangkan siswa dalam kelompok rendah mempunyai kemampuan transformasional yang cenderung rendah, kemampuan generasional yang rendah sampai sedang, dan kemampuan level-meta global yang rendah sampai sedang. Algebraic thinking is a representation of activities and abilities to learn school algebraic. The aim of this research was to determine the ability of eighth grade junior high school students in algebraic thinking. The method used in this research was the qualitative descriptive approach. This research was conducted with giving a test of algebraic thinking skills to the students. Furthermore, based on test results, students are grouped according to their algebraic thinking skills which consists of a high­level group, moderate­level group and low­level group. From each group, two subjects were selected to be interviewed more related their algebraic thinking skills, as a representative for their each group. Analytical results from this research indicated that the ability in generational, transformational, and global meta­level activities is already visible in some eighth grade students. Students were included in the high­level group tend to have high skill in generational, transformational, and global meta­level activities. While students were included in the low­level group tend to have low skill in transformational ability, low to medium skill in generational ability, and low to medium skill in global meta­level ability.
