The main objectives of this research were to explore the current circumstances regarding principal knowledge leadership, teacher professional development, and school performance in high-quality senior high schools, and to analyze the relationships between these three variables by using a mediated effects model. To achieve these objectives, this study adopted a questionnaire survey. The sample comprised 1,025 teachers from 60 high-quality senior high schools in Taiwan. The conclusions of this research indicated the following: 1. Performance was high in the dimensions of “building professional expertise” pertaining to principal knowledge leadership, “the promotion of educational knowledge and ability” regarding teacher professional development, and “the effectiveness of curriculum and instruction” in regard to school performance; 2. Significantly positive relationships were observed between principal knowledge leadership and teacher professional development, between principal knowledge leadership and school performance, and between teacher professional development and school performance; 3. Principal knowledge leadership exerted significant indirect effects on school performance, mediated by teacher professional development; and 4. Testing with the multiple-mediator model revealed that principal knowledge leadership exerted significant indirect effects on school performance, mediated by the factors of “team learning and growth” and “the expression of professionalism” in regard to teacher professional development. |
