IMPLEMENTATION OF THE PROBLEM BASED LEARNING (PBL) MODEL TO ENHANCE THE MATHEMATICAL PROBLEM-SOLVING ABILITY OF TENTH GRADE VOCATIONAL SCHOOL STUDENTS
Abstract
This study aims to improve the learning process and enhance students' Mathematical Problem-Solving Ability (MPSA) in the Statistics and Probability content for Class X Agrihan 2 at SMKN Pertanian Terpadu Riau through the implementation of the Problem Based Learning (PBL) model. This study employed a Classroom Action Research (CAR) method, conducted over two cycles, with each cycle comprising the stages of planning, implementation, observation, and reflection. The subjects of this study were 32 students of Class X Agrihan 2 at SMKN Pertanian Terpadu Riau in the 2023/2024 academic year, with heterogeneous ability levels. The results showed an improvement in students' MPSA, with the mean score increasing from 26.7 in the initial test to 50.5 in Cycle I, and 84.6 in Cycle II. Based on these results, it can be concluded that the implementation of the Problem Based Learning (PBL) model effectively improved the quality of the learning process and enhanced the Mathematical Problem-Solving Ability of students in Class X Agrihan 2 at SMKN Pertanian Terpadu Riau.
