Cognitive load assessment in computer based video training for the purposes of one-hand knot tying

Type: dissertation
Study design: Clinical Trial
Abstract: The purpose of practice is to enable learning and this can be indirectly observed through performance. The current study employed the dual task methodology to assess the effectiveness of computer based video training during the practice of the one-hand knot tying among novice learners. Sixteen students were randomly assigned to one of two groups: practice and non-practice groups. A pre-recorded instructional video was presented to all participants. The practice group completed 10 trials of the one-hand knot tying on a bench top simulator, while the non-practice group did not. All returned a week later for a transfer task. Subjective ratings of mental effort and reaction time were indices of cognitive load. Time on task served as an indication of task performance. Results showed the practice group had reduced cognitive load and shorter performance times compared to the no practice counterparts. These findings imply that self-directed practice alongside Computer based video training (CBVT) is an effective tool in teaching technical clinical skills.
