The first part was an examination of the students' written explanations of fractals and the second part was an analysis of the students' fractal drawings. The questionnaire was developed by the researcher based on previous studies in the areas of teaching and learning fractals.

The findings showed that students had problems both in personal concept definitions and the formal definition of fractals. Moreover, students' fractal drawings were more successful than their formal definitions.
