The reform and improvement requires a change from teachers building their own intellectual engagement and on-the-job teacher learning to teachers working collaboratively as leaders of the school site [12]. Thus, in order to enable teachers to work collaboratively for improved instructional practices, changes in school curricula could be a major step towards productive teacher collaboration. It would align the scope and sequence of what should be taught and learned, and teachers could collaborate with one another on daily lessons.
Similarly, educational policymakers have also recognized the importance of organizational design and effective leadership in establishing and maintaining vibrant learning communities for both teachers and students [13]. Shared decision-making, collective actions regarding school policies and reflection on broader school reform issues are seen as promising ways to engage teachers, foster collegiality, and improve practice. A professional learning community can be a pre-condition for effective teacher leadership and also be sustained by the collegial practices of teacher-led schools [14].
