Geography learning with a spatial perspective should be delivered more openly. Modern geography learning must be capable of taking advantage of social space as a learning experience, with students' spatial citizenship skills by utilizing geomedia technology and geographic information system. The SIHyL model is projected to respond to these challenges. This study aims to determine the effectiveness of SIHyL model in improving students’ spatial citizenship. SIHyL model, for geography learning, is constructive, inquiry, and hybrid. SIHyL model is effective in increasing students' spatial citizenship skills. Effectiveness of the model is proven by the increase in N-Gain score in every prototype test. In terms of effectiveness in SIHyL model after the effect size test, the score of first cycle was 0.809617, while second cycle was 0.706696. Moreover, the score for first prototype test was 1.098876, while second prototype test was 1.547322. Based on the results of effect size test, SIHyL model is effectively applied in geography learning to improve spatial citizenship skills. Students respond to the implementation of SIHyL model to increase spatial citizenship and to show their enthusiasm and satisfaction in following the learning process.
