Özet:

The research is in the relative scan model aimed at determining the relationship between the shared leadership practices applied in schools and the organizational sinism levels of teachers. The universe of research 2018-2019 educational year consists of teachers who work in primary, secondary and secondary schools in Denizli province. A total of 5865 teachers in the Denizli province form the universe of research. The study includes 407 teachers who work in the Maritime Province. In the study, the data was collected with the "Share Leadership Perception Scale" and the "Organized Synism Scale for Teachers". The data was looked at the scores of confusion and depression for the research variables to determine which types of analyses should be performed. Since the data is normally distributed, the analysis has used the T-Test, ANOVA and Pearson Moments Collapse Correlation and Multi-Regression Analysis techniques. The results of the study can be stated in this way. Research shows that teachers have a high level of perception of shared leadership practices in schools. The study found that teachers’ perceptions of the state of implementation of shared leadership in schools were similar to gender and working hours in the same school. Again, the study found significant differences between the teachers' professional age, the number of teachers in the school and the variable of the school level being studied, while some dimensions of shared leadership found significant differences between the teachers' perceptions towards the implementation diaries. According to the other variables of the study, the organizational sinism levels of teachers are also low. Organizational sinism levels vary according to the gender of teachers, the number of teachers in the school they work and the level of school they work. According to the variation of the time of work in the same school, the levels of sinism of the teachers are not different. Again, the perceptions of teachers about shared leadership practices in schools and the organizational sinism levels have a significant negative middle-level relationship. The study ultimately found that shared leadership practices in schools significantly influenced teachers’ organizational sinism levels at all school levels. The increase in shared leadership practices in schools leads to a decrease in teachers’ organizational sinism levels.Therefore, school managers need to be trained to raise awareness about this.
