Kemampuan Metakognisi Siswa dalam Pemecahan Masalah pada Materi Bangun Datar di Kelas VII SMP

This research aims to describe about students' metacognition of problem solving on plane geometry in 7th grade SMP. The research method is descriptive with case study. The subjects of this research are four students grade VIII C consist of two high students group, two middle students group, two low students group in problem solving. The result of this research shows that the student metacognition of high group in problem solving almost all indicators good in each planning process, monitoring or evaluating. Meanwhile, the ability of metacognition students of middle group in problem solving is not better than high group when planned completion in each planning process, monitoring or evaluating. For ability of metacognition students of low group in problem solving where all indicators not so good in each planning process, monitoring or evaluating.
