Research on students' adoption of course-specific approaches to learning in parallel courses is limited and inconsistent. This study investigated second-semester psychology students' levels of deep, surface and strategic approaches in two courses running in parallel within a real-life university setting. The results showed significant differences in course-specific adoption regardless of approach. However, the strategic approach seemed more stable. Sub-groups of students exhibited substantial variation: more than half of the students adopted similar approaches in both courses while large minorities showed great variability. Students scoring low on the surface approach, high on the deep approach or high on the strategic approach to learning were flexible in adopting different parallel approaches. However, students scoring high on the surface approach, low on the deep approach or low on the strategic approach seemed stable across contexts. This suggests that even smaller variations in teaching and learning environments can influence students' approaches to learning.
