Operationalisation of the terms “I can”, “I did” and “the student can” (Table 1A) and of the supervision levels on a 6-point scale (Table 1B) as used in the study. The third column of Table 1B indicates how the supervision scale used in this study relates to the Chen-scale for undergraduate medical education (Chen et al., 2015)
