Implementation of Problem-based Learning Model to Enhance Students Learning Outcomes in Buffer Solutions Topic

Abstract

This research aims to determine the improvement of the process and learning outcomes of the buffer solutions topic by applying the Problem-based Learning (PBL) model. This research is based on Classroom Action Research (CAR) takes place in two cycles, with several stages including planning, implementing, observing, and reflecting. Our present study used 17 students of natural science 11th grade SMA Advent Manokwari. The data was obtained from teachers and students. The data collection method used cognitive learning outcomes and observation. The data analysis uses descriptive analytic techniques. Our findings showed that the application of the PBL model can improve the quality of the learning process on the buffer solutions topic; the application of the Problem-based Learning (PBL) learning model has increased from cycle I with an average grade of 65.36 and a percentage of passing grades of 41% and cycle II with an average grade of 83.66 and a percentage of passing grades of 88%.

Meningkatkan Hasil Belajar Kognitif Siswa Kelas Xii Ipa Sma Negeri Karas Fakfak Pada Materi Sifat Koligatif Larutan Melalui Penerapan Model Problem Based Learning (Pbl)

“…Hasil penelitian Utami et al (2018) menyatakan bahwa terdapat perbedaan hasil belajar kognitif siswa dalam penggunaan model pembelajaran Problem Based Learning (PBL) dengan peserta didik yang diajar dengan pembelajaran konvensional, dimana terdapat pengaruh sebesar 30%. Selain itu penelitian Letlora et al (2021) menyatakan bahwa penerapan model PBL dapat meningkatkan kualitas proses pembelajaran dan dapat meningkatkan hasil belajar dari siklus I ke ssiklus II. Berdasarkan hasil ini, penelitian ini berorientasi pada penelitian Tindakan kelas (PTK).…”
