Although mathematics education has traditionally entailed a passive acquisition of knowledge (Bird, 2023), this approach no longer meets the needs and demands of an “increasingly volatile, uncertain, complex and ambiguous” world (OECD, 2018, p. 3). Over the last few decades, mathematics education has responded to these changes through reforms in mathematics curricula to emphasise 21st century priorities such as reasoning and non-routine problem solving (Goos et al., 2020). Research indicates that challenging tasks in mathematics are an effective medium for developing these higher order skills, while preparing students both academically and holistically (Sullivan et al., 2012). Despite this, there is limited research on challenging tasks in the secondary context. To date, research has focused on challenging task interventions, related teaching strategies and their impact, primarily in primary education settings.
Therefore, this research will focus on secondary mathematics teachers’ implementation of challenging tasks through an investigation of their conceptions of and orientations towards these tasks. Adopting an exploratory design using both qualitative and quantitative data sources, this study will use an online questionnaire and semi-structured interviews (Stages 1 & 2) to help understand how these conceptions and orientations influence teachers’ pedagogical decisions to implement or not implement challenging tasks. Classroom observations (Stage 3) will be conducted to observe challenging tasks in action. Bronfenbrenner’s (1979) Bioecological Systems Theory will be used to identify and categorise enablers and barriers to the implementation of challenging tasks that emerge from the triangulated findings.
