Computer becomes an essential tool for teachers at schools, especially in teaching and learning processes. Therefore, teachers need to be informed about computer assisted instruction and develop various skills through both pre and in-service training courses they enrolled during their professional developments. Knowing how they could utilize this knowledge and skills they gained, and which and how software would be helpful in courses are among the questions that should be answered at the end of any pre-service course. Thus, this study aimed to examine the views of primary school mathematics teachers on the applicability of GeoGebra, as a dynamic mathematics software program for teaching mathematics. In this study, as it allows a deep investigation of a certain group and the data obtained from the data collection tools were investigated without making any generalizations case study method was preferred.
