The effects of video-based and blended learning on medication dosage calculation skills of paramedic students: A randomized, quasi-experimental study.

Background: Medication dosage calculation (MDC) is a vital component of clinical competence for healthcare providers, particularly in emergency medical services, where miscalculations can lead to life-threatening outcomes. This study aimed to compare and evaluate the effects of video-based learning (VBL) and blended learning (BL) on the MDC skills of paramedic students, with the hypothesis that BL would result in higher posttest MDC performance compared to VBL.

Methods: A randomized quasi-experimental design was used. A total of 151 paramedic students were randomly assigned to 2 groups. Both groups received a 2-week e-learning course that included video-based content and task-based exercises. Additionally, the BL group received an 8-hour classroom-based training session during the same 2-week period, which was scheduled as a single full-day session on the third day of the first week. Following the intervention, both groups completed a posttest assessing their MDC skills.

Results: The BL group achieved significantly higher posttest scores (82.19 ± 13.74) compared to the VBL group (72.24 ± 21.87), with the difference being statistically significant (P = .001).

Conclusion: While both methods were effective in enhancing MDC skills, BL was more effective. E-learning materials require further development to function as a fully independent instructional approach.
