Learning geography for an individual starts with the relationship between human and location. This relationship develops depending on gaining some skills which are necessary for understanding and using the geographical location as effective as possible. One of the main goals of high school geography education is to enable individuals to gain skills which will increase their spatial perceptions. This geography curriculum whose main elements are skills, concepts, values, and attitudes and which has also been used since 2005 has been prepared according to this aim. Thus, availability of geographical skills exclusive to geography lessons shows that. The aim of this research is to study realization levels of geographical skills which are eight in total. Therefore, realization levels of the skills 9th and 12th grade students gained in geography lessons have been detected and compared to each other. For that reason, a scale developed by the researcher was conducted to the 9th and 12th grade students and the results have statistically been discussed. According to available results, it has been found out that skills realization level of 9th grade students is rather low and 12th grade students’ realization level developed dramatically. However, some skills have developed in 9th grade or 12th grade as acquisition belonging to the lesson is unequal. Within the framework of the findings of the study, it is has been suggested that in order to increase the realization level of geographical skills, “skill-based” activities which will be a guide to the teachers during the learning-teaching process should be focused. Besides, it should be noted that, in order to stop unequal skill developments, the acquisitions in which each skill is represented in each grade in the educational program.
