Development Of High School Geography Learning Devices Based On Spatial Thinking In The City Of Samarinda

Abstract

Spatial Thinking is a thinking skill that needs to be possessed and needs to be developed in learning geography, this is because geography is a scientific discipline that examines the phenomenon of the earth's surface (geosphere) with material objects in the form of the lithosphere, atmosphere, hydrosphere biosphere and anthroposphere as well as the formal object in the form of a spatial approach, environment and area complex. As the main component in developing spatial thinking skills in schools, it is necessary to have supportive learning tools. This study aims to develop a spatial thinking-based geography learning tool in terms of validity, practicality, and effectiveness. This study uses a research and development (r & d) approach which is designed using the ADDIE model which consists of analize, design, develop, implement, evaluate. The test subjects consisted of material experts, linguists, media experts, geography teachers in Samarinda City, and high school students. Data were analyzed using descriptive statistics. The results of the study are in the form of learning tools which include: syllabus, lesson plans, teaching materials, student worksheets, learning media, and assessment instruments that have been validated by experts with very good feasibility. The validity aspect is considered very valid with a score of 0.85, while the practicality aspect is considered very practical with a score of 0.9. Based on this, it can be concluded that the developed learning tools can be used in geography learning activities.
