Problem-Oriented Self-Efficacy Perception Scale for Mathematical Creativity: Validity and Reliability Studies

The study aims to develop the Problem-Oriented Self-Efficacy Perception Scale for Mathematical Creativity to determine the pre-service mathematics teachers’ mathematical creativity self-efficacy perception in a valid and reliable way. The exploratory sequential mixed method was preferred for the research. In the research, while qualitative procedures were followed during the item pool preparation, the scales' psychometric properties were researched using quantitative methods. The convenience sampling method was used to determine the participants. The research was conducted with primary school pre-service mathematics teachers studying in four state urban universities in three different regions (Black Sea Region, Eastern Anatolia Region, Southeastern Anatolia Region) of Turkey. The first study group constituted of three hundred eleven pre-service mathematics teachers while the second study group three hundred sixty-four pre-service mathematics teachers. As a result of the research, a 3-factor structure consisting of fluency, flexibility, and originality factors, and explaining 61.527% of the total variance was obtained. Validity and reliability calculations of the scale consisting of 21 items in 5-point Likert type resulted positively.
