The purpose of this study is to investigate the development of relational thinking skills, which are an important component of the transition from arithmetic to algebra, in 12th grade students. In the study, the qualitative research method of teaching experiments was used. The research data were collected from +2 students by means of clinical interviews and teaching episodes. To observe the development of relational thinking, pre- and post-clinical interviews were also conducted before and after the 5-session teaching experiment. Qualitative analysis of the research data revealed that the relational thinking skills of all the students developed......
