The aim of the study is to determine trends in Turkish Mathematics Education on the basis of both master and doctoral theses involved. The researchers reviewed the online databases of the Higher Education Council and Proquest as well as the library of each university and examined 284 graduate theses in regard to research topic, research methods, data collection and sample. The document analysis has pointed out that the number of the theses' focusing research problem on "teaching mathematics" is quite high when compared with the other thesis focused different research topics and it is seen an increase in the number of the theses written around that problem. In addition, it was determined that the most preferable research design by mathematics education researchers "was experimental design" and the most preferable data collection instruments were "questionnaires" and "achievement tests". Within this process, researchers mostly preferred working on the 6th, 7th and 8th grade students. (Contains 7 tables.)
