The data of the research was collected through a questionnaire that is formed of three open-ended questions to determine the opinions of teacher candidates about multiculturalism and multicultural education.

There are questions in the questionnaire to determine the opinions of teacher candidates about multiculturalism, multicultural education and their capacities to practice this multicultural education. The data was analyzed through descriptive analysis method. The descriptive analysis was implemented in four stages. In the first stage, the data was read by researchers and draft codes were built. Draft codes were combined and themes were created in the second stage. Then themes and codes were reorganized in order to make them easier for readers to understand. In the last stage, findings obtained were presented in tables as frequencies and percentages. In order to increase the internal reliability of the research data, the data was recoded individually by two researchers and then two researchers came together to examine the consistency between analyses. General agreement coefficient between researchers was determined to be .78. When the answers of teacher candidates to the question "Define multiculturalism concept?" were examined, it was seen that opinions fell under two different themes; in terms of individuals and Society. It was determined that classroom and preschool teacher candidates define multiculturalism as to know about different cultures in terms of individuals and various cultures living together in terms of society.
