Turkish student's sketch maps of the Islamic world is the basic data for this study. During 1998-2000 collected 400 sketch maps and made questionnaire among the geography students, who were chosen randomly, from different universities of geography departments in Turkey. Students in geography classes were given a blank sheet of paper and asked to sketch map of the Islamic world. In drawing the sketcher is trying to reproduce a world political map and Islamic countries from memory, since the instructions explicitly ask for the names of all Islamic countries. The individual map scores are aggregated to determine the average number of items per map for each site and Islamic country. Sketch maps reflects students geographic literacy. From the analysis of the mental maps of the students are that the role conceived for the teaching of geography greatly influences the knowledge of the place and countries name localities of the world. Some of the students -of geography- are incapable of placing correctly more than 20 countries. In the most extreme case is Turkish Republic of Northern Cyprus, TRNC is ranked 30th and this ignorance is disturbing. Main other characteristics of the mental map of Turkish geography students is factor of proximity and current events. Area, total Muslim population or Muslim portions of countries are not affected on mental maps.
