Table 4.
A comparison of the cognitive load between the intervention group (n = 149) and control group (n = 150) with regard to the cognitive load at three defined points in time (CL1 after the theoretical introduction; CL2 after the practical demonstration; CL3 after the practical training); the cognitive load is described as the mean (± standard deviation) on a 9-step Likert scale (very, very low mental effort up to very, very high mental effort).
| Intervention Group | Control Group | Intervention vs. Control | |
|---|---|---|---|
| cognitive load (CL1) | 2.79 (± 1.291) | 2.85 (± 1.353) | p = 0.688 |
| cognitive load (CL2) | 3.66 (± 1.441) | 3.43 (± 1.472) | p = 0.159 |
| cognitive load (CL3) | 4.75 (± 1.774) | 4.19 (± 1.860) | p = 0.008 |
