ANALISIS KETERAMPILAN BERPIKIR ALJABAR SISWA KELAS VIII MTs
Abstract
Abstrak
Penelitian ini bertujuan untuk mengetahui jenis keterampilan berpikir aljabar siswa. Fokus dalam penelitian ini adalah kemampuan generasional, kemampuan transformasional, dan kemampuan level-meta global. Jenis penelitian ini adalah penelitian dekskriptif kualitatif. Subjek penelitian ini adalah siswa kelas VIII MTs Ganrang Batu Kabupaten Jeneponto sebanyak 29 orang, yang selanjutnya dipilih menjadi subjek wawancara adalah 6 orang. Teknik pengumpulan data menggunakan tes diagnostik dan wawancara mendalam. Hasil penelitian ini menunjukkan bahwa: 1) kemampuan generasional siswa subjek kategori tinggi dan sedang cenderung mampu pada indikator menentukan makna variabel dari suatu masalah dan mempresentasikan masalah dalam hubungan antar variabel. Subjek pada kategori rendah belum mampu dalam aktivitas generasional, 2) kemampuan transformasional siswa kategori tinggi cenderung mampu pada indikator menentukan bentuk aljabar yang ekuivalen dan menyelesaikan operasi bentuk aljabar. Subjek pada kategori sedang dalam aktivitas transformasional mampu menyelesaikan operasi bentuk aljabar, sedangkan subjek pada kategori rendah belum mampu dalam aktivitas generasional baik pada indikator menentukan bentuk aljabar yang ekuivalen maupun menyelesaikan operasi bentuk aljabar 3) kemampuan level-meta global siswa kategori tinggi, kategori sedang, dan kategori rendah cenderung belum mampu dalam indikator menggunakan aljabar untuk menganalisis perubahan, hubungan, dan memprediksi suatu masalah dalam matematika dan menggunakan aljabar untuk memodelkan masalah dan menyelesaikannya.
Abstract
This study aims to determine the types of students' algebraic thinking skills. The focus in this research is generational abilities, transformational abilities, and global meta-level capabilities. This type of research is qualitative descriptive research. The subjects of this research were 29th grade students of Mts Ganrang Batu, Jeneponto Regency with 29 people, who were subsequently chosen as the subjects of the interviews were 6 people. Data collection techniques using diagnostic tests and in-depth interviews. The results of this study indicate that: 1) the generational abilities of high and medium category subject students tend to be able to determine the meaning of variable indicators of a problem and present problems in the relationships between variables. Subjects in the low category have not been able to be in generational activities, 2) the transformational abilities of high category students tend to be able to on indicators determine the equivalent algebraic form and complete the operation of the algebraic form. Subjects in the medium category in transformational activities are able to complete algebraic form operations, while subjects in the low category have not been able to in generational activities either on indicators determining equivalent algebraic forms or completing algebraic form operations 3) global meta-level ability of high category students, medium categories, and low categories tend not to be able to use indicators of algebra to analyze changes, relationships, and predict problems in mathematics and use algebra to model problems and solve them.
