The senior secondary Mathematical Methods subject was introduced in Queensland in 2019 and parents were concerned with the low grades attained. Students in the subject need to develop extensive procedural knowledge and fluency to participate and engage successfully. This mixed methods study informed by constructivism investigated teachers' perceptions on how procedural flowcharts can enhance procedural fluency in the subject. Data were collected through a survey and semi structured interviews with the subject teachers. The study found that procedural flowcharts can foster a classroom environment that stimulates procedural fluency and student-centred teaching and learning of mathematics. The study suggests the potential for using procedural flowcharts in other mathematics subjects at different levels of study.
