All Rights Reserved.As in every profession, those who work in the field of education follow the rapidly developing technology and adapt these innovations to their profession has become one of the most important requirements of today. It is not enough to equip teachers and students with new technologies to develop 21st century skills; these technologies need to be successfully integrated into classes. Teachers’ adoption of innovative teaching approaches and educational technologies depends on their ability to use these approaches and technologies successfully. The aim of this study is to demonstrate the importance of Geographical Information Systems (GIS) in geography teaching and to provide basic map information and GIS skills to geography teaching. In this context, 21 geography teachers and 4 academicians have been employed within the scope of “Basic Map Information and GIS Applications (TEHABIS)” supported by TUBITAK. In this study, the following questions were sought: (1) What is the knowledge level of teachers about basic map information and GIS applications? (2) How has the TEHABIS project affected the knowledge level of teachers about basic map information and GIS applications? (3) What are the challenges encountered during GIS training? Findings revealed that participants had deficiencies in basic map information before the project but increased motivation to learn advanced cartography issues at the end of activities. In addition, the participants stated that they would use the information they obtained from the project in relation to teaching, dissemination and quality of teaching.
