In a rapidly changing world, it is impossible to shape education environment of contemporary children by teachers’ previous knowledge. It is a known fact that teachers who follow innovative methods and techniques on education, use games and activities for in-class and out-class implementations, use information technologies actively, value colleagues’ cooperation and sharing knowledge can create more efficient learning experiences. On the other hand, in service teacher training studies in Turkey focus more on theoretical information than practice. With this in mind, the purpose of this study is to develop a workshop model which can provide more active internal knowledge sharing processes. This study was conducted at a primary school in Istanbul as a part of vocational studies during June 2015. To design workshop studies, personal information forms that identified teachers’ vocational qualifications and requirements and focus group interviews were used. The attending teachers designed activities and games for 11 different topics. Workshops were performed for two different groups which consisted of 19 teachers each on a rotation basis.After two weeks of workshop studies, education evaluation survey was realized. It was found that workshop studies were found useful and helpful by participant teachers. Further studies like the one in this study that take into account internal education requirements and use internal human resources can help promote teacher professional development
