This study aims to determine the effect of using a matrix board teaching aid on students’ conceptual understanding of matrix operations at SMKS YPKP TIK Sentani. This study employed a quantitative approach using a pre-experimental method with a One-Group Pretest-Posttest design. The sample consisted of 66 students from classes XI LPKC 2 and XI LPKC 3, selected through purposive sampling. The research instrument was a conceptual understanding test that was evaluated for content validity using the Content Validity Index (CVI), construct validity, and reliability using Cronbach’s Alpha. The validated instrument was administered as a pretest and posttest to measure students’ conceptual understanding before and after the treatment. The collected data were analyzed using IBM SPSS Statistics version 26. Data analysis included a normality test to determine the distribution of the data and a paired-sample t-test to examine differences in students’ conceptual understanding before and after the intervention. The results showed that the data were normally distributed. Furthermore, the paired-sample t-test yielded a significance value of 0.000, which was lower than 0.05. Therefore, H0 was rejected, indicating a significant difference between students’ conceptual understanding before and after the treatment. These findings demonstrate that the matrix board teaching aid has a positive and significant effect on students’ conceptual understanding of matrix operations.
