Abstract

The problem in the learning process is that many students lack focus and motivation to learn when teachers deliver material. The cause is a learning model that is not interactive enough, where teachers often use a one-way learning approach. In addition, teachers have not mastered or utilized interactive learning media beyond the use of PowerPoint. This condition not only reduces the effectiveness of learning but also has a negative impact on students' critical thinking and problem-solving abilities. The purpose of this study is to look at how using a Problem-Based Learning method with electronic module media affects students' ability to think critically and solve problems in the subject of Electronics Basics at State Vocational High School 4 Pariaman. This research is a quantitative study that uses an experimental approach, specifically a Quasi-Experimental Design called the Non-Equivalent Control Group Design. The students involved were all from class X TEI during the 2022/2023 school year. The data analysis showed that using the Problem-Based Learning method with Augmented Reality media had a significant effect on the critical thinking and problem-solving skills of Industrial Electronics Engineering students. The control group saw an average improvement of 24.81%, while the experimental group had an average improvement of 22.13%.
