Spatial thinking skills is needed in geography learning. Geography learning learns about the geosphere, which need to be studied from the perspective of spatial, environment, and regional complex. This is consistent with the concept of spatial thinking, which involves complex thinking processes from multiple perspectives to study various phenomena. This research aims to determine the effect and effectiveness of using webgis inarisk media towards spatial thinking skills. This research was conducted through a quantitative method with data analysis using T-Test (Independent Sample T-Test) and the effectiveness test using (N-Gain Score Test). The results showed the Sig. (2-tailed) value in the analysis of the Independent Sample T-Test was 0.001 or more than 0.05. The average score of spatial thinking ability also showed that the experiment group (XI IPS 2) has a score of 70.3 which is higher than the control group (XI IPS 1) that is 64.2. Based on this, it is concluded that the webgis inarisk as a learning media has an effect on students' spatial thinking abilities. The results of the N-Gain Score test showed that webgis inarsik media used in experiment group (XI IPS 2) has better effectiveness in the achievement of spatial thinking skills, which is 43.7 percent, compared to map media used in control group (XI IPS 1) with an effectiveness of 32.09 percent.

The study population was all eighth-grade students of SMP Negeri 12 Bandar Lampung (Junior High School) for the 2019/2020 academic year, distributed in nine classes. Of the nine classes, one class was selected as the experimental class and one class as the control class. The research design used was the pretest-posttest control group design. The data was collected using a test of reflective mathematical thinking skills and a students' self-concept questionnaire. Test and questionnaire results were analyzed descriptively and inferentially. The results showed that the percentage of students in the PQ4R class with good categories in reflective mathematical thinking and self-concept was more than 60% of students' total number. The increase in mathematical reflective thinking ability and self-concept of students who took PQ4R learning was not higher than the increase in students who follow conventional learning. Thus, it can be concluded that the PQ4R learning method was ineffective in terms of students’ mathematical reflective thinking skills and self-concept.
