In addition, this new method is useful for students to prepare digital mapping skills for future geoscience professions. Digital fieldwork is gaining popularity internationally across geoscience and geographical education, but there have been no case studies conducted in Thailand. Traditional teaching methods in fieldwork including paper-based mapping, geochemical sampling, collecting geophysical data, and using remote sensing are commonly used in many Thai universities. This teaching method could potentially benefit any science teaching and have applications in other disciplines requiring similar skills as well. Therefore, the ArcGIS Online application plays an important role in changing and developing the geological fieldwork in Thailand at the university scale for students. Results from independent t-tests between treated and untreated student groups show that the average post-test scores of the treated students were significantly higher than pre-test scores, at a p = 0.05 level, after using ArcGIS Online in fieldwork designed in this study. This observation indicates that students can think about the structure and deformation events as spatial continuity during acquisition data gathering in the field. In comparison to traditional classrooms, this teaching method enables students to more easily comprehend how geological structures and features connect through the mapping area. This brief report describes an educational innovation for geological fieldwork with the ArcGIS Online application to examine students’ learning experiences. Applying ArcGIS Online application to geological fieldwork provides an alternative way to teach students.
