The Effect of Problem Based Learning Model Assisted by Augmented Reality Media on Critical Thinking Students

Abstract

Problems in the learning process are that many students lack focus and lack motivation to learn when the teacher delivers the material. The cause is one of the learning models that is less interactive, where teachers often use a one-way learning approach. In addition, teachers have not mastered or utilized more interactive learning media outside of using PowerPoint. This condition not only reduces the effectiveness of learning, but also has a negative impact on students' critical thinking. The purpose of this study was to analyze the effect of implementing the Problem Based Learning model assisted by Augmented Reality media on students' critical thinking in Computer Engineering and Networking subjects at state vocational high school 1 Bukittinggi. This study is included in the type of qualitative research with an experimental method, using the Quasi Experimental Design model in the form of Nonequivalent Control Group Design. The subjects of this study were all class XI TJKT students in the 2024/2025 academic year. Based on the results of the data analysis, it shows a significant effect of the application of the Problem Based Learning model assisted by Augmented Reality media on the critical thinking of Computer Engineering and Networking students with a contribution of 73.65%.
