The Impact of Teacher Leadership and Positive School Culture on the Performance of Students in Public and Private Secondary Schools in Beirut and Mount Lebanon (MBA thesis, Haigazian University)https://doi.org/10.62811/th.0141https://haigrepository.haigazian.edu.lb/handle/123456789/104The purpose of the study was to examine the role of teachers as leaders and the role of positive school culture on the performance of students. Moreover, this study aimed to show whether teacher leadership and positive school culture are positively affecting the successful performance of students, and whether the public and private secondary school students in Beirut and Mount Lebanon are performing equally successfully. An empirical study was performed using a survey questionnaire, which was distributed to 413 grade-12 students from 32 schools. The sample included 201 students from schools located in Beirut from which 110 students belong to private schools and 91 students belong to public schools; and 212 students from schools located in Mount Lebanon from which 115 students belong to private schools, and 97 students belong to public schools. Descriptive Statistics were conducted followed by Reliability Tests, Multiple Regression with Stepwise Method, Independent Sample T-Test, and Factor Analysis. Empirical evidence from this study showed that teacher leadership and school culture vi totally differ between the two types of schools: Private and Public schools. Private schools have better teacher leadership and a more positive school culture compared to public schools. Students in private schools build positive relationships with teachers, are engaged in school life, have a sense of school belonging, participate in classroom activities, are confident of succeeding in their exams, and achieve higher averages than students in public schools. Moreover, the study revealed that several factors regarding teacher leadership and positive school culture are better in schools in Beirut than in Mount Lebanon. That is why students in schools in Beirut build better and more positive relationships with teachers, and are more confident that they are capable of succeeding in their exams. This study recommended public schools to pay more attention to all the factors including teacher leadership and positive culture that contributed to the betterment of the private schools. Also, the schools in Mount Lebanon should learn why the schools in Beirut are doing better. In particular, they will benefit from knowing that the reasons for the differences are that in Beirut teachers are able to make their objectives clear, teachers are knowledgeable, teachers help students resolve problems or conflicts, teachers help improve skills and abilities of students, there is a supportive environment that motivates students to learn, high expectations of leaders regarding achievements, and the culture is oriented towards continuous improvement of the school.
