Description
Summary:Abstract: The research objectives are (1) describing the mistakes made by students in simplifying fractions of algebraic forms and (2) describing the scaffolding given to overcome student errors. The subjects in this study were UM Lab High School students in the XI IPS class who made mistakes in completing the test. The research subjects studied were 2 students categorized in the low ability category. This type of research is descriptive qualitative. Data obtained through tests and interviews. The results showed that (1) the mistakes made by students in simplifying the algebraic fractions consisted of errors in denominator equations, errors in algebraic operations, errors in algebraic factoring and errors in simplified algebraic fractions and (2) scaffolding given based on errors in point one is explaining, reviewing and restructuring and developing conceptual thinking. Abstrak: Tujuan penelitian adalah (1) mendeskripsikan kesalahan yang dilakukan oleh siswa dalam menyederhanakan pecahan bentuk aljabar dan (2) mendeskripsikan scaffolding yang diberikan untuk mengatasi kesalahan siswa. Subjek dalam penelitian ini adalah siswa SMA Lab UM kelas XI IPS yang melakukan kesalahan dalam menyelesaikan tes. Subjek penelitian yang diteliti sebanyak 2 siswa yang dikategorikan dalam kategori kemampuan rendah. Jenis penelitian ini adalah kualitatif deskriptif. Data yang diperoleh melalui tes dan wawancara. Hasil penelitian menunjukan bahwa (1) kesalahan yang dilakukan siswa dalam menyederhanakan pecahan bentuk aljabar terdiri dari kesalahan pada penyamaan penyebut, kesalahan pada operasi aljabar, kesalahan pada pemfaktoran aljabar dan kesalahan pada penyederhanaan pecahan aljabar dan (2) scaffolding yang diberikan berdasarkan kesalahan pada poin satu adalah explaining, reviewing dan restructuring serta developing conceptual thinking.
