Implementation of Problem-Based Learning to Improve Students' Mathematics Learning Outcomes Class X Computer and Network Engineering Vocational School
Abstract
This study aims to enhance the mathematics learning outcomes of Class X students by implementing Problem-Based Learning (PBL) at SMK Negeri 1 Bengkalis. The research method employed is Classroom Action Research (PTK), involving Class X Computer and Network Engineering (TKJ) students as the research subjects. The study was conducted during the odd semester of the 2021/2022 academic year, from August 12, 2021, to November 30, 2021, and consisted of two cycles. Each cycle included stages of planning, implementation, observation, and reflection. The findings indicate that applying PBL significantly improved students' mathematics learning outcomes, with an increase of 62.86% in Cycle I and 97.43% in Cycle II. These results demonstrate that PBL is an effective teaching model for enhancing student engagement and conceptual understanding in mathematics. Therefore, PBL can be a valuable learning paradigm to help students at SMK Negeri 1 Bengkalis study mathematics more effectively and deeply.
