To support AST's effort in building a teacher-led culture of professional excellence centered on the holistic development of our students, we strive to enhance research literacy and promote critical inquiry among the teaching fraternity.

What support is provided for teachers embarking on Critical Inquiry?

We strive to build a culture in which teachers view the critical inquiry of their teaching and learning as an integral part of their professional practice. To nurture such a culture, situating critical inquiry in professional learning communities within schools is a first step.

AST also provides the following support to encourage teachers to embark on their Critical Inquiry journey:

AST designs and organises a series of courses to equip teachers with the knowledge and skills in conducting critical inquiry for their professional development. Sign up for a course of your choice through OPAL2.0.

As reflective practitioners, teachers in professional learning communities can make use of various critical inquiry methods to systematically investigate their instructional practices. This will help them reflect upon and refine their classroom practices collaboratively, to continually improve student learning.
