'Reflections on teaching and learning from the AITSL on YouTube. In a linguistically and culturally diverse preschool setting, a teacher builds on emerging student interests. The teacher trials a number of learning opportunities where students can observe phenomena and the properties of everyday materials and develop concepts about the relationships of volume/sound/pitch. Through observation, she develops an understanding of the importance of responding to the stage of development of individual students. With an educational leader from her local government area she discusses how she might further develop her teaching skills. She outlines the value of to her own professional development of informal conversations with colleagues, independent research and professional learning with peers across the area.
