Abstract

This study aims to test the effectiveness of the use of Augmented Reality (AR) technology in the Project Based Learning (PjBL) model on improving students' questioning and critical thinking skills. The method used is a quasi-experimental method with a non-equivalent control group design. The subjects of the study were students of grade XI SMAN 14 Samarinda who were divided into an experimental class and a control class, each consisting of 20 students. The research instruments used were essay tests, observation sheets, and documentation. The data analysis techniques used were descriptive statistics (mean and standard deviation), N-Gain test, t-test (Independent Sample T-Test), and Normality & Homogeneity test using SPSS 25 for Windows. The results of the analysis showed a more significant increase in skills in the experimental class compared to the control class. The N-Gain value of the experimental class' questioning skills was 0.46 (moderate category), while the control class was 0.21 (low). For critical thinking, the experimental class obtained 0.51 (moderate), higher than the control class 0.33 (moderate). These findings indicate that AR integration in PjBL effectively improves questioning and critical thinking skills, and contributes to 21st century learning innovation.

Abstract

Brain Based Learning is an approach based on how the human brain works. This model creates a learning atmosphere that is in harmony with the way the brain naturally processes information, with the hope of increasing student participation and their learning outcomes. In its implementation, the Brain Based Learning model is combined with the use of Wordwalls as a learning aid. Wordwall is a technology-based platform that offers a variety of user-friendly quizzes, games, and activities. This study aims to determine the effect of the use of the Brain Based Learning model and Wordwalls on science process skills and student learning outcomes. This type of research is a quasi-experimental study using a Pretest-Posttest Control Group Design. The research instrument uses a test, with 10 essay questions, 5 questions to measure science process skills, and 5 questions to measure student learning outcomes. The sampling technique in this study uses the Purposive Sampling technique. To analyze the data, the researcher used the t-test with a significance level of 0.05. The results of the analysis show that the t-test obtained a sig. A 2-tailed test of 0.00 (0.00<0.05) for both variables indicates an effect of the Brain-Based Learning model assisted by Wordwall media on the science process skills and learning outcomes of 11th-grade students at SMA Negeri 13 Samarinda on the human sensory system topic.
