<![CDATA[This study aims to examine the effectiveness of using Google Earth Pro as a learning tool in helping tenth-grade students at SMA Negeri 1 Batusangkar understand spatial concepts better. This study uses a quantitative approach with a quasi-experimental method and an unequal control group design. This study involved two classes, namely the experimental class and the control class, each consisting of 33 students. This study showed a significant improvement in the experimental class that used Google Earth Pro. The average score of the post-test reached 93.21, while the score of the pre-test was only 71.94. The experimental class had an N-Gain score of 0.86 which is included in the "Effective" category, better than the control class which only achieved a score of 0.73 in the "Quite Effective" category. Hypothesis testing using the t-test showed a statistically significant difference (p < 0.001) with a very large effect size, namely Cohen's d = 3.232. It is known that the use of Google Earth Pro is very effective in improving students' understanding of spatial concepts in geography lessons.]]>
