The objective of this research is to examine the relationship between teachers' teaching-learning conceptions and pedagogical competence perceptions and to reveal the related findings. The research was designed in the relational survey model. The study group of the research is composed of teachers who work in elementary and secondary public schools in Karaman district of Turkey (n = 223). In the research, it was found that there are positive or negative relationships between teachers' teaching-learning conceptions and pedagogical competence perceptions sub-dimensions. In addition, according to regression analysis, it was seen that the model was significant as a whole and teachers' teaching-learning conceptions and pedagogical competence perceptions were significantly associated. It was understood that the teachers' teaching-learning conceptions explained 42% of their pedagogical competence perceptions. According to the findings of the research, it was observed that teachers mostly had traditional teaching-learning conceptions and there was no significant relationship between their traditional teaching-learning conceptions and their pedagogical competence perceptions except the first dimension. It was found that there was a significantly positive relationship between their teaching-learning conceptions and their pedagogical competence perceptions among teachers who have constructivist teaching-learning conception. According to these findings, teachers' pedagogical competence perception levels decrease as their teaching-learning conceptions move towards the traditional conceptions, and pedagogical competence perception levels increases as their teaching-learning conceptions move towards constructivism. When all these results are taken into consideration, teachers should be educated in accordance with the constructivist teaching-learning conception in line with their contemporary educational philosophies, models and conceptions.
