The aim of this study is to evaluate the applicability of Geographic Information Systems (GIS), used increasingly in primary and secondary education across the world, in social studies lessons in Turkey. In line with this aim, 14 social studies teachers working in the province of Aydin, Turkey received a 6-hour training course about GIS during the 2011-2012 academic year. The training covered theoretical information on GIS, a demonstration of ArcGIS 9.2--a GIS software widely used in the world, and the presentation of GIS-based teaching materials prepared by the researcher prepared in accordace with the Turkish national social studies curriculum for primary schools. Following the training, interviews were conducted with the teachers, during which their views were sought regarding the applicability of GIS in social studies lessons in primary education, its benefits, potential difficulties, and what action should be taken. Data were collected using a "Teacher Interview Form" consisting of 6 open-ended questions developed by the researcher. Content analysis was used for the data analysis. The study revealed that the teachers found GIS considerably useful in primary education due to its ability to enable students to learn visually, improve their map skills, and promote retention. However, the teachers also mentioned several potential problems, including their own shortcomings in using both computers and GIS, the lack of time allotted for such activities, students' inadequate computer skills, and the level of difficulty of GIS since it has been found to be rather difficult for the students. A number of solutions to these problems have been proposed in the study.
