RESUMO
BACKGROUND: The Covid-19 pandemic has changed the education system throughout the world. This study aimed to compare synchronous online lecturing with blended flipped classroom plus jigsaw in terms of their effects on the students' learning, communication skills and critical thinking disposition. METHODS: This is an educational intervention conducted at the Nursing and Midwifery School of Shiraz University of Medical Sciences. Two incoming students of nursing and midwifery were selected by complete enumeration. Then synchronous online lecturing was given to one group (n = 40) and blended flipped classroom and jigsaw to the other (n = 44). After that, given the prevailing conditions, both methods were performed fully online. Then Participants completed an online questionnaire. A researcher-made learning questionnaire, the Interpersonal Communication Skills Questionnaire developed by Fetro, and Ricketts' Critical Thinking Disposition Inventory were used to assess the study variables. RESULTS: The mean learning scores in the blended group were slightly higher but this difference was not significant (P = 0.767). In the blended group, the mean scores of communication skills were significantly higher after the intervention in all the dimensions, except for empathy & intimacy and listening skills. In the online lecture group, there was no significant difference between before and after the intervention. Communication skills (P < 0.001) scored significantly higher in the blended group after the intervention than that in the synchronous online lecturing group in all the dimensions except for empathy & intimacy. In the online lecture group, there was no significant difference in critical thinking disposition between before and after the intervention. In the blended group, the overall score of critical thinking disposition and its dimensions was significantly higher after the intervention (P < 0.001), except for the perfection dimension. There was no significant difference between the two groups in terms of the mean total score of critical thinking disposition and its dimensions before and after the intervention. CONCLUSION: Given the global circumstances, the blended method was more effective in promoting learning outcomes and communication skills than synchronous online lectures. Furthermore, it seems that this new approach could improve critical thinking.
