PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) DALAM MENINGKATKAN PRESTASI BELAJAR KIMIA MATERI STOIKIOMETRI PADA SISWA KELAS X-MIA 5 SMA NEGERI 3 PADANGSIDIMPUAN TAHUN AJARAN 2022/2023

Abstract

Abstract

This research aims to determine the effect of applying the Problem Based Learning (PBL) learning model on the chemistry learning achievement of class X-MIA 5 students at SMA Negeri 3 Padangsidimpuan Academic Year 2022/2023 on Stoichiometry material. The population of this research is all class X-MIA high school students in the 2022/2023 academic year. Due to limited time, funds, personnel and facilities to support this research, the students studied were only students at SMA Negeri 3 Padangsidimpuan class X-MIA 5, Odd Semester in the 2022/2023 Academic Year, totaling 30 students. The research method used was Class Action Research (CAR) in 2 cycles. This research design includes four stages, namely: planning, acting, observing and reflecting. The instruments used as data collection tools are tests and non-tests. The data analysis techniques used in this research are descriptive statistical analysis (percentages) and inferential statistical analysis (t-test and N-gain). The results of the research show that the Problem Based Learning (PBL) learning model has a significant effect on the chemistry learning outcomes of class X-MIA 5 students at SMA Negeri 3 Padangsidimpuan for the 2022/2023 academic year on Stoichiometry material. The Problem Based Learning (PBL) learning model succeeded in increasing the chemistry learning achievement of class X-MIA 5 students at SMA Negeri 3 Padangsidimpuan for the 2022/2023 academic year on Stoichiometry material. The increase in chemistry learning achievement obtained in cycle I was 44.19% and cycle II was 53.97%.
