Özet:

Many different barriers have been identified which limit integration of spatial technologies into secondary school education. Because of these challenges teachers tend to concentrate traditional teaching methods instead of removing obstacles on using spatial technologies. However, we may remove physical (lack of hardware, software) and technical (lack of computer) barriers in terms of requirements of geography teachers. Geography teachers who can combine their technological skills with pedagogical and field knowledge are the ones who meets today's educational needs. It is necessary to organize in-service training (IST) activities that can meet today's needs in geography education, prepared in line with the needs of teachers and helpful in developing their technological competencies, to which they can participate voluntarily. The aim of this study was to develop, implement and evaluate in-service training GIS course among geography teachers using an open source software, free data and geographical technological pedagogical content knowledge (G-TPACK) model. The research employed both qualitative and quantitative research methods and techniques. Our study proved that in-service GIS training which was admired to attend by teachers according to the needs analysis, have improved their skills and knowledge.
