A total of 124 student teachers, who were studying to become
secondary biology teachers at the Faculty of Education in Selcuk
University in Turkey, participated in this study. The average age of
students was 22.3 years (range 21 - 25). The majority of students
were females (76 of 124). However, this study was not focused on
gender differences. In the literature no high gender differences
were found in this field (Kibbos et al., 2004). Thus, the gender
difference was not examined in this study. Participants previously
had studied cell division in cytology, genetics, and molecular
biology, as a school subject during various semesters. Research
was conducted in October, 2008.
