Abstract

Nowadays, learning mathematics is often considered difficult and boring for students. This boredom is caused by learning that is carried out by teachers that are less innovative. This can be one of the factors that contribute to the low critical thinking skills of students. This study aims to see the effectiveness of using a project-based learning model with the help of augmented reality media in improving students' mathematical critical thinking skills. The method used was quasi experiment research. The sample was 53 primary school students using simple random sampling technique. The experimental class was taught with project-based learning model using AR media, while the control class was taught with conventional learning model. Data were collected through observation and tests. Data analysis used quantitative analysis and inferential statistics. The independent sample t-test showed that the resulting probability value was smaller than 5%, which was 0.025 on one side and 0.050 on both sides. These results indicate a significant difference in students' mathematical critical thinking skills where the experimental class is superior to the control class.The One Sample T-test revealed that the average score was over 60, suggesting that students using project-based learning with augmented reality media improved their math critical thinking skills significantly. The N-Gain test showed a high improvement rate of 0.98 in the experimental class and a medium rate of 0,51 in the control class. Overall, it was found that using project-based learning with augmented reality media effectively enhances students' math critical thinking skills
