The purpose of this study is to compare the theses written on environmental education in Turkey and in the Czech-Republic. Within the scope of this study, which is conducted by using document analysis, the theses written in Turkey and the Czech-Republic about environmental education in 2007-2013 were compared in terms of year of issue, the type of the sampling and the type of the program in which the thesis is completed. The findings revealed that in 2007-2013, there are totally 130 theses written in Turkey and 49 theses written in the Czech-Republic. While the samplings of the theses written in Turkey mostly consist of pre-service teachers, the samplings of the theses completed in the Czech-Republic are comprised of elementary and high school students. Finally, it was determined that most of the theses in both of the countries were written in the departments affiliated to elementary school education.
