Alenezi, Abdulaziz Sh2023-01-112023-01-112023-01-10vt_gsexam:36332http://hdl.handle.net/10919/113117According to the findings of the 2019 Trends in International Mathematics and Science Study (TIMSS), fourth-grade students from Gulf Cooperation Council (GCC) countries—consisting of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates—performed below average compared to other countries on mathematics and science assessments. Despite this, little organizational research has examined potential factors that might have contributed to these results or sought to quantify the variability in school effectiveness in GCC countries. Hence, the present study sought to address this gap by quantifying the variability in school effectiveness in these countries. Using TIMSS 2019 data and multilevel analysis within each GCC member state, the study found school effectiveness varied significantly, ranging between 17% and 60%, considerably more than the variation typically seen in Western countries. In addition, several school-level organizational factors showed a significant impact on school effectiveness. Schools with more adequate resources, higher-quality teachers, greater parental involvement at the school level, and a safer and more orderly environment tended to display higher effectiveness as measured by average mathematics achievement. This finding should encourage researchers and policymakers to have more informed discussions about school effectiveness in the region.ETDenIn CopyrightSchool EffectivenessStudent AchievementGCCSchool ResourcesSchool ClimateParental InvolvementTeacher QualityDissertation
