Scaffolding untuk Mengatasi Hambatan Berpikir Siswa Dalam Menyelesaikan Masalah Sudut pada Dimensi Tiga
Abstract
Abstract: The pupose of this research is to describe the thinking barriers of high school students in solving angle problems in the three dimensions. This research is a qualitative descriptive study. Data obtained from student tes result in solving problems, interviews and scaffolding. Subjects in this study are high school students who have learned abaut the angle between the line with the plane in the three dimensions. The results showed that subjects 1 (S1) and subject 2 (S2) experienced obstacles in solving angle problems in the three dimensions. High-ability student thinking barriers occur at the stage of devising a plan implementing a carrying out plan and looking back due to lack of initial knowledge, lack of student analogy skills, and lack of connection ability students. While the low-ability student thinking impediment occurs in the stage of drafting a devising plan which continues in the step of carrying out the plan and looking back.
Abstrak: Tujuan penelitian ini adalah untuk mendeskripsikan hambatan berpikir siswa SMA dalam menyelesaikan masalah sudut pada dimensi tiga. Penelitian ini merupakan penelitian deskriptif kualitatif. Data diperoleh dari hasil pekerjaan siswa dalam menyelesaikan masalah, wawancara, dan scaffolding. Subjek dalam penelitian ini adalah siswa SMA yang telah memperoleh materi sudut antara garis dengan bidang pada dimensi tiga. Hasil penelitian menunjukkan subjek 1 (S1) dan subjek 2 (S2) mengalami hambatan dalam menyelesaikan masalah sudut pada dimensi tiga. Hambatan berpikir siswa kemampuan tinggi (S1) terjadi pada tahap menyusun rencana penyelesaian, melaksanakan rencana penyelesaian, dan memeriksa kembali yang dikarenakan kurangnya pengetahuan awal, kurangnya kemampuan analogi siswa, dan kurangnya kemampuan koneksi siswa. Hambatan berpikir siswa kemampuan rendah (S2) terjadi pada tahap menyusun rencana penyelesaian yang berlanjut pada langkah melaksanakan rencana penyelesaian dan memeriksa kembali
