Spatial reasoning has been shown to be an important, trainable cognitive skillset for developing successful engagement in science, technology, engineering and mathematics (STEM), but little empirical work has been conducted in the context of digitally mediated pedagogies. This paper reports on a study into the effectiveness of a technologically enhanced STEM program on the spatial reasoning of a cohort of year 7 students (n = 107). The students undertook five digitally based activities over the period of a week and were assessed on their spatial reasoning development and attitudes towards STEM prior and subsequent to the intervention. Results indicate that the week of learning activities had an impact on attitudes towards STEM and had a positive impact on overall spatial skills. However, no statistically significant improvements were found within the spatial sub-skills or in relation to specific activities.
