<![CDATA[The primary objective of this research was to analyze the effect of implementing technology-based geography learning using ArcGIS digital maps on the enhancement of spatial thinking ability among Grade X students at SMA Negeri 8 Medan. This study was motivated by findings indicating low levels of student spatial ability and the minimal use of innovative media supporting geospatial literacy. The research employed a Quasi-Experimental Method with a Nonequivalent Control Group Pretest-Posttest Design. The research sample consisted of two groups selected through Purposive Sampling: the Experimental Group (N=35), which received treatment using ArcGIS learning, and the Control Group (N=31), which used conventional methods. Spatial thinking ability data were collected via test instruments and analyzed using the Independent Samples t-test on the Gain Score. The results demonstrated a significant increase in Gain Score in both groups. However, the Experimental Group's mean Gain Score (31.46) was substantially higher than that of the Control Group (17.93). Hypothesis testing confirmed a highly statistically significant difference, evidenced by a p-value of 0.000 (p < 0.05). The conclusion of this study is that the implementation of Geography learning based on Digital Maps with ArcGIS is significantly effective in enhancing students' spatial thinking ability. This finding underscores the crucial role of geospatial technology in optimizing students' spatial analysis competency.]]>
