The Influence of Principal Leadership Management and Teamwork Through Achievement Motivation on Improving School Quality in Batam City Public Senior High Schools

Abstract

This study aims to analyze the influence of principal leadership management and teamwork on achievement motivation and its implications for improving school quality among teachers of public senior high schools in Batam City. This research employed a quantitative approach using a survey method through the distribution of questionnaires to 240 respondents who were teachers of public senior high schools in Batam City. The data analysis technique used in this study was Partial Least Square (PLS) with the assistance of SmartPLS 4.0 software to examine the relationships among the research variables. The results of the descriptive analysis indicate that all research variables are in the high category, namely principal leadership management with a score of 89.2, teamwork with a score of 92.4, achievement motivation with a score of 90.7, and school quality with a score of

89.3. The results of the outer model test show that all research indicators meet the validity and reliability criteria with loading factor values above 0.6, Cronbach's Alpha and Composite Reliability values above 0.7, and Average Variance Extracted (AVE) values above 0.5. The results of the inner model test show that the R-Square value is 0.575 for the achievement motivation variable and 0.622 for the school quality variable, which are categorized as moderate. The results of hypothesis testing indicate that principal leadership management does not have a significant effect on achievement motivation. However, principal leadership management has a positive and significant effect on school quality. Teamwork is proven to have a positive and significant effect on achievement motivation but does not have a significant effect on school quality. Meanwhile, achievement motivation has a positive and significant effect on school quality. The results of the mediation effect test indicate that achievement motivation does not mediate the relationship between principal leadership management and school quality, but it mediates the relationship between teamwork and school quality. Based on the results of the study, it can be concluded that the improvement of school quality is directly influenced by principal leadership management and achievement motivation, and indirectly influenced by teamwork through achievement motivation. Therefore, improving school quality can be achieved through strengthening principal leadership management, enhancing teamwork, and developing teachers’ achievement motivation.
