The aim of the study was to investigate the role of school organizational culture on the lean behaviors of elementary school principals by the mediating role of their coaching leadership. The research population was all primary school teachers in Ilam province, from which a sample of 339 teachers was selected using proportional stratified random sampling based on Cochran's formula.

For data collection, Denison's (2000) organizational culture questionnaire; Pilaz Zuborbuhler et al. (2021) coaching leadership questionnaire as well as, the researcher-made questionnaire of lean behaviors of school principals were used. The reliability and validity of the questionnaires were investigated with Cronbach's alpha techniques, content validity ratio, exploratory factor analysis and confirmatory factor analysis. In order to analyze data and test research hypotheses, correlation matrix analysis and structural equation modeling were used with SPSS.v25 and LISREL.v10 software. The results indicated that: 1) the four types of organizational culture (involvement, adaptability, mission and consistency) had a direct, positive and significant effect on the lean behaviors of school principals 2) the four types of organizational culture had an indirect, positive and significant effect on the lean behaviors of school principals through mediating role of their coaching leadership. 3) Four types of organizational culture and coaching leadership of school principals estimated 59% of the variance of their lean behaviors.

Therefore, the present study was conducted with the aim of studying the mediating role of intellectual ethics in the relationship between digital leadership and smart decision-making among elementary school principals in Kermanshah province. Material and Methods: The research is a correlational research based on structural equation modeling of the correlation-covariance matrix. The statistical population includes all the elementary principals of Kermanshah province in the academic year 2021-2022 (N=1902). The sample size was estimated based on proportional stratified random sampling and Cochran's formula (n=320). The tools included intelligent leadership, intellectual ethics and smart decision-making questionnaires, whose content validity was confirmed by experts and professors, and their construct validity was confirmed by factor analysis. The reliability of the questionnaires was calculated through Cronbach's alpha as 0.85, 0.93 and 0.95 respectively. Pearson's correlation test and structural equation modeling were used for data analysis, and SPSS and LISREL software were used. Results: The relationship between digital leadership and intellectual ethics, digital leadership and intelligent decision-making, and the relationship between intellectual ethics and smart decision-making were significant. Finally, it was found that intellectual ethics can play a mediating role in the relationship between digital leadership and smart decision making.

The research was a descriptive correlational study. The study population was 16750 people in all secondary school teachers in Khuzestan province in 1400-1399, from which a sample of 407 people was selected based on Cochran's formula by stratified random sampling.
