In this episode of MathsTalk, host Leanne McMahon discusses the pressing issue of out-of-field teaching in mathematics education. With recent media attention on AMSI's analysis of out-of-field secondary maths teaching and upskilling initiatives in Australia, Leanne explores the complexities of defining out-of-field teaching and its various dimensions, including qualification, specialism, workload, and capability. Drawing from extensive research and insightful anecdotes, she discusses the impact of out-of-field teaching on student learning and offers practical strategies for upskilling teachers, emphasizing the importance of government funding for retraining initiatives. Through engaging discussions and resource recommendations, including the invaluable Out of Field Teaching Toolkit podcast, McMahon aims to ignite a conversation and provide actionable solutions to enhance the quality of mathematics education across Australia.
