The aim of the study was to investigate the role of synergistic leadership of school principals and systematic innovation of school organization in organizational entrepreneurship with the mediation of organizational ambidexterity and teachers' productive behaviors. The research population was all the teachers of technical and vocational schools in Tehran province, and a sample of 364 teachers was selected from this population using proportional stratified random sampling based on Cochran's formula. The quantitative research method is correlation studies and covariance-based structural equation modeling approach. In order to collect data from the researcher-made Synergistic leadership questionnaire; the researcher-made Systematic innovation questionnaire; the Organizational ambidexterity questionnaire of Jansen (2006); the researcher-made Teachers' productive behaviors questionnaire; and the Organizational entrepreneurship questionnaire of Hughes & Morgan (2007) were used. The reliability and validity of questionnaires were evaluated by the Cronbach's alpha techniques, content validity ratio, exploratory factor analysis and confirmatory factor analysis. In order to analyze the data and test the research hypotheses, correlation matrix analysis and structural equation modeling were used by SPSS 25 and LISREL 10.5 software. The results showed that: synergistic leadership and systematic innovation had a direct, positive and significant effect on organizational ambidexterity, teachers' productive behaviors and organizational entrepreneurship. synergistic leadership and systematic innovation had a positive and significant indirect effect on organizational entrepreneurship through organizational ambidexterity and teachers' productive behaviors. The variables of synergistic leadership, systematic innovation, organizational ambidexterity and teachers' productive behaviors were able to explain 0.37 of the variance of organizational entrepreneurship

Objective: This study investigated the effect of wisdom therapy (general and personal) on academic procrastination among elementary school students. Method: This quasi-experimental study used a pre-test-post-test design with two experimental groups and a control group. The population included 230 female students from Pardis 2 Primary School (grades 4–6) in Songhor Kolyaei city in 2021–2022. Fifty-one students identified as high academic procrastinators (top 25% in delayed homework submission) were randomly selected and assigned to experimental group A (n = 17), experimental group B (n = 17), and a control group (n = 17). Academic procrastination was assessed behaviorally through direct observation and systematic recording of delays in submitting a non-curricular assignment over three stages. The experimental groups received six weekly 60-minute wisdom therapy sessions based on Dr. Kord Noqabi’s Wisdom Therapy (protocol year 2020), focusing on reflective thinking, identifying cognitive distortions, clarifying personal values, and creating action plans. The control group received no intervention. Data were analyzed using multivariate analysis of covariance (MANCOVA) in SPSS version 22. Results: Both experimental groups showed a significant reduction in academic procrastination (p < 0.01), with personal wisdom therapy demonstrating a stronger effect than general wisdom therapy (p < 0.05). Conclusions: Wisdom therapy effectively reduces academic procrastination among elementary students. Incorporating wisdom-based strategies into educational programs is recommended to enhance academic responsibility and student performance.

The purpose of this research is meta-analysis of the factors related to the philosophical mindset of students based on the researches published in the last 10 years. The population of this research is all the researches published in scientific journals. The sampling method was based on the Purposive sampling method. In this way, out of the total number of researches, which was 13, 3 of the researches were excluded due to reasons such as incompleteness of statistical information. In fact, studies that reported the necessary information and used correct statistical tests were selected, and studies that did not report the necessary information were excluded. The statistical sample is based on the researches that have been carried out on the factors related to the philosophical mindset of students, and their number is 10 researches (14 factors). In order to select studies suitable for meta-analysis and extract appropriate information, meta-analysis checklists were used. These checklists include researchers' names, research title, year of publication, place of implementation, statistical population and sample size, gender, educational level, research tools, reliability and significance level. CMA3 software was used to analyze the results. According to the research results, the effect size and Z calculated for 12 variables out of 14 variables are significant. Also, the largest effect size is related to t self-direction , creativity ,also the smallest effect size is related to mathematical self-efficacy and problem solving . Also, the effect size for all studies in the fixed and random model is at a high level.

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. This is a quantitative correlational research study through covariance-based structural equation modeling approach. 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. They were elementary. 4) Among all types of organizational     culture, adaptability culture had the highest effect on principals' lean behaviors

This research was conducted with the aim of investigating the role of digital leadership and technology flexibility in intelligent decision-making with the mediation of intellectual ethics and team reception. The research method is quantitative, descriptive and of the type of correlation studies based on the covariance-oriented structural equation modeling approach. The research population was all the elementary principals of Kermanshah province, of those 320 principals were selected through stratified random sampling based on Cochran's formula. To collect data, researcher-made questionnaires of digital leadership, technological flexibility, intelligent decision-making, intellectual ethics and team reception Soltani (2008) were used. The content validity of the questionnaires was confirmed by experts, supervisors and consultants. The reliability of the questionnaires according to Cronbach's Alpha was 0.94 for digital leadership, 0.91 for technology flexibility, 0.95 for intelligent decision making, 0.93 for intellectual ethics, and 0.89 for team reception.  To analyze the data, the descriptive as well as inferential analysis techniques were used through SPSS and LISREL software. Structural equation modeling showed that digital leadership has a direct effect on team reception, intellectual ethics and intelligent decision making. Moreover, digital leadership has an indirect effect on intelligent decision-making through team reception and intellectual ethics. The flexibility of technology has a direct impact on intellectual ethics, team reception and intelligent decision making. Technology flexibility has an indirect effect on intelligent decision-making through intellectual ethics and team reception. Intellectual ethics has a direct impact on team reception and intelligent decision making. Intellectual ethics has an indirect effect on intelligent decision making through team reception.
