Linking leadership practices, professional learning community and student performance in Hong Kong secondary schools Objectives The focus of the study was to investigate the influence of leadership practices on student outcomes, being mediated through the creation of a professional learning community. Adopting a quantitative methodology, the study specifically aimed: 1. To explore the direct effect of leadership practices on student performance; and 2. To examine the mediating effect of professional learning community on influencing the link between leadership practices on student performance; Theoretical Framework In a review of research on school leadership, Hallinger and Heck (1999) found that leaders effectively influence school outcomes indirectly through multiple variables. Southworth (2005) also notes that “effective school leaders work directly on their indirect influence” (p. 102). Principals exercise some form of influence on creating appropriate conditions and culture that have a direct influence on students (Leithwood & Day, 2007). Professional learning community is one of the most commonly found school condition variables introduced in the literature; it serves as a mediator whose main function is to generate a mechanism through which the focal independent variable is able to influence the depend variable of interest (Baron & Kenny, 1986). In other words, professional learning community (the mediating variable) has a direct effect on student performance (dependent variable) and it is in turn affected by school leadership (independent variable). Although the effect of school leadership on student outcomes has been widely recognized, empirical evidence to support this link is lacking in the literature. The work of Day and his team (2009) in the UK is one of the few endeavours that address this area. This study attempted to investigate the influence of school leadership practices on student outcomes through understanding the effect of leadership practices on professional learning community building in Hong Kong secondary schools. Specifically, my study was guided by the framework shown in Figure 1. The assessment of leadership practices is varied and complicated depending on the theoretical framework researchers espouses (Antonakis, Cianciolo & Sternberg, 2004). In this study, I adopted a 7-dimension framework that is used by the Education Bureau to assess the responsibilities of principals in Hong Kong. The seven dimensions are: External communication and Connection, Quality Assurance and Accountability, Teaching, Learning, and Curriculum, Staff Management, Resource Management, Leader and Teacher Growth and Development, and Strategic Direction. Research focus on professional learning community (PLC) thus far has focused either on its impact on student learning or the school conditions conducive to teacher capacity development. For instance, Pedder (2006) drawing on the findings from a large-scale study in the UK covering 1906 students confirmed the contribution of teachers’ professional learning to student academic outcomes. Bolam and his research team (2005) also maintained that the development of a professional learning community in schools was a determining factor affecting student achievement. Thompson and his colleagues (2004) also advocated that the building of a professional learning community amongst teachers not only enhanced the knowledge base of the group but also had a significant impact on their work in their classrooms. Apparently, there are few studies that attempt to link leadership, teacher capacity and student outcomes together. The measure of student performance, the dependent construct in the study, was drawn from the quality assurance framework used by the Hong Kong Education Bureau to assess the performance of students (EDB, 2008). Two sets of performance indicators were adopted in the study; one to measure students’ academic achievement and the other their behavioural outcomes. Methodology The instrument used in this study comprised 61 items; 33 for measuring the 7 leadership practice dimensions (Kwan & Walker, 2008), 4 for PLC, 3 for student academic performance and 3 for student behavioural performance. The study targeted at vice-principals (VPs) as informants for their more objective evaluation on leadership enactment in schools. The instrument was sent to in VPs in all Hong Kong secondary schools. Respondents were asked to indicate the agreement to all the 33 statements on a 6-point Likert’s scale. A total of 179 responses were obtained. Findings Confirmatory factor analysis was conducted to validate the measurement model structure for leadership practices using LISREL. The following goodness of fit statistics was obtained, 2=886.79 (df=272), RMSEA=.063, CFI=.91, and NNFI=.90 suggesting a good fit of the model to the data. The reliability alphas for all scales were found to be in a satisfactory range (from .701 to .856). An aggregated score for all 7 leadership practices was also computed for further analysis. Kim, Kaye and Wright’s (2001) suggestion on testing the mediating effect of a variable was followed in the study; three analyses were run and tested for significance: (1) regressing the mediator on the independent variable; (2) regressing the dependent variable on the independent variable and (3) regressing the dependent variable on both mediator and independent variables simultaneously. Two sets of regression analyses with professional learning community (PLC) as mediator, aggregated leadership score (AL) as the independent variable, and student academic and behavioural performance as respective dependent variable were run. The results are shown in Table 1. Table 1 to be inserted here With three significant regressions established, the result of AL in regression (3) was compared with that of regression (2) in each of the sets. As both sets of results suggested a significant reduction in the value, so the partial mediating effect of PLC on student academic and behavioural outcomes was confirmed. The findings suggested that leadership practices had a both direct and indirect effect on student outcomes and the latter was mediated through PLC. With a view to exploring the respective effect of the leadership practices, a series of regression was run with the 7 leadership practices as independent variables. The results are shown in Table 2. Table 2 to be inserted here The findings showed that only the leadership practice of Teaching, Learning and Curriculum had a direct effect on student performance. It also suggested that a mechanism set in schools to monitor student learning could also alleviate students’ behavioural problems. The regression results further showed that the leadership practices of Leader and Teacher Growth and Development as well as Staff Management were predictors for Professional Learning Community. Schools in which whose leaders had focused at “develop[ing] leaders among school teachers”, “promot[ing] a range of continuous professional development experiences among all staff”, “us[ing] coaching and mentoring to improve quality of teaching”, and “encourag[ing] staff to think of learning beyond the academic curriculum” were more conducive to the development of teacher collaboration. Results of the study showed that leadership practices which are directly linked to teaching and learning, such as focusing at “teaching, learning and curriculum” and “quality assurance and accountability” could lead to student academic outcomes improvement. Effort in developing collaboration among teachers also appeared to be warranted. School leaders should be more visionary and forward looking; instead of establishing a quality assurance system in schools to monitor the learning outcomes of students, school leaders are encouraged to place more attention to the professional development of teachers. A team of competent teachers is the essential element for enhancing the performance of students. Significance of the study The study can contribute to the literature in a number of ways. First, it provides an empirical support to the well established and yet to be validated claim in the literature that the effect of leadership practices on student academic outcomes was indirect and it was mediated through the building of a professional learning community. Secondly, it also informs school leaders that developing and motivating teachers to meet future challenges rather than narrowly focusing at teaching and learning quality assurance mechanisms can also help student learning.
