PENGARUH MODEL PROBLEM BASED LEARNING (PBL) BERBASIS AKTIVITAS METAKOGNISI TERHADAP KEMAMPUAN MEMECAHKAN MASALAH KELARUTAN DAN HASIL KALI KELARUTAN PADA SISWA KELAS XI SMA NEGERI 2 BANJARMASIN

Abstract. This study aims to determine the effect of PBL model of metacognition activity based in learning solubility equilibria and the solubility product in class XI SMAN 2 Banjarmasin. This research method is a quasi- experimental design with nonequivalent control group design. The population was a student of class XI IPA SMAN 2 Banjarmasin. Samples were taken by purposive sampling, and class XI IPA 1 as the experimental class and XI IPA 3 as the control class. Data collection techniques using problem-solving test, observation and inventory sheets.
