In this episode, Greg and Caiti discuss recent research into mobile phone bans in schools, exploring whether they’re actually effective and why schools may choose to implement them in the first place. They also unpack debates around teacher autonomy, low-variance teaching and standardised curriculum resources, questioning whether shared approaches are truly a threat to professionalism or a way to improve consistency and reduce workload. Finally, they explore critical thinking in the Australian Curriculum and the relationship between knowledge, thinking and evidence-informed practice.
