Videos of demonstration versus text and image-based material for pre-skill conceptualisation in flipped newborn resuscitation training for medical students: a pilot study

Abstract

BackgroundThe flipped skills lab is a student-centred approach which incorporates pre-class preparation (pre-skill conceptualization) followed by repeated, hands-on practice for practical skills training. Objective measures of skills acquisition in the flipped literature are few and conflicting. The importance of pre-skill conceptualization in flipped skills training suggests that pedagogically informed pre-skill conceptualization can enhance outcomes.MethodsA mixed quasi-experimental study was conducted on 41 final year medical students who followed a flipped newborn resuscitation skills lab. Pre-class preparatory material covered conceptual and procedural knowledge. Students in the traditional group (n=19) and those in the experimental group (n=22) received identical reading material covering conceptual knowledge. Procedural knowledge was shared as demonstration videos to the experimental group, while the traditional group received a PowerPoint presentation with text and images covering the same material. Knowledge acquisition was assessed by 20 single best answer questions before and after hands-on practice in the skills lab and skill performance was tested post-intervention with a simulated scenario. Students’ perceptions were collected by survey. Quantitative data was analysed using Wilcoxon Signed Ranks test and Mann-Whitney test as appropriate. Qualitative data was analysed by thematic analysis.ResultsOverall student rating of the intervention was positive with ratings of 4.54 and 4.46 out of 5 by the traditional group and the experimental group respectively. Post-intervention skill performance in the experimental group was significantly better (p<.05) in the experimental group (M=87.86%, SD=5.89) than in the traditional group (M=83.44, SD=5.30) with a medium effect size (r=.40). While both groups showed significant knowledge gains, only students in the experimental group showed a statistically significant gain in procedural knowledge (p<.05) following the flipped skills lab. Finally, while both groups self-reported feeling more knowledgeable and confident following the intervention, the level of confidence was superior in the experimental group.ConclusionsFlipping the skills lab with pre-skill conceptualisation combining text-based conceptual knowledge and video-based procedural knowledge followed by simulation-based hands-on practice improves procedural knowledge and skills acquisition in newborn resuscitation training for medical students. This study shows that in addition to temporal benefits, pedagogically informed pre-skill conceptualization can confer procedure-specific cognitive and emotional benefits supporting skills acquisition.
