Many studies have demonstrated that spatial reasoning is malleable and that improvements in spatial reasoning transfer to mathematics (Hawes et al., 2022). A recent review of the spatial training literature (Resnick & Adams, 2024) found that most studies use cognitive frameworks to explain their findings, suggesting that transfer is achieved through improvements in directly applicable spatial skills (e.g., Cheung et al., 2020). Only two studies considered other pathways, such as changes in students’ strategic approach (Lowrie et al., 2019; 2023). Despite increasing interest in explaining why spatial training supports mathematics, most studies did not examine mechanism (Resnick & Adams, 2024). This may be driven, in part, by the methodologies employed (Young et al., 2018).
The present study utilised qualitative methods to examine Year 11 mathematics students’ strategic approaches toward solving mathematics problems before and after completing a spatial training intervention. Students’ work samples and verbal explanations were first used to develop response maps (Stillman & Galbraith, 1998) outlining students’ solutions and coded based on the strategic approach employed. Subsequently, students’ cognitive and metacognitive behaviours were coded using Garofalo and Lester’s (1985) framework. Improvements were observed in students’ ability to correctly encode spatial information. Furthermore, students’ improved representational skills helped them to avoid unhelpful, naïve, non-spatial strategies.
