<![CDATA[Learning activity and learning outcomes in mathematics remain low, partly because learning is dominated by lectures with conventional media. This study aims to determine the effect of Canva-based visual learning media on the learning activity and mathematics learning outcomes of Grade XI students at State Senior High School 1 Batang Toru on the topic of circles. The study used a quantitative approach with a quasi-experimental method and a Pretest-Posttest Control Group Design. The sample consisted of class XI-3 as the experimental class with 35 students and class XI-2 as the control class with 35 students. The instruments were a learning outcome test of five essay items, which was valid and reliable with a Cronbach's Alpha of 0.9488, and a learning activity observation sheet. The data were analyzed using the Liliefors normality test, the F homogeneity test, a one-tailed t-test, and the normalized gain. The mean posttest score of the experimental class was 90.86, higher than that of the control class at 85.71. The average normalized gain was 72.38% (high category) for the experimental class and 58.43% (moderate category) for the control class. The t-count of 2.9043 was greater than the t-table of 1.667 at a significance level of 0.05, so the null hypothesis was rejected. The learning activity of the experimental class was categorized as active to very active. Therefore, the mathematics learning outcomes of students who used Canva-based visual learning media were significantly higher than those of students who used conventional media.]]>
