Thank you for the invitation to review this interesting and well-presented manuscript. Multi-campus medical schools are not common in most parts of the world, though a few organizations are working toward setting up campuses at multiple locations and ensuring standardized delivery of teaching-learning and course materials and assessment across sites.
The Otago Medical School according to the description in the manuscript pursues different curricula and teaching-learning activities across the three campuses. I am interested in knowing why this model was chosen instead of having the three campuses as separate medical schools. In Australia, Canada and I assume also New Zealand education in rural healthcare facilities is considered very important and students spend considerable time in these locations. From the reference to the Moodle logs description, my understanding is that the study was conducted in 2015 and there is a lag period between the study conduct and the publication. In the interim several changes have occurred including the coronavirus pandemic which has given a major fillip to online learning. What type of topic-based learning resources were created? Did these use videos or web-based clinical scenarios? Were all students accessing the resources from cities and towns? Did any students access these resources from rural areas? Were there any internet bandwidth issues? I did not fully understand about the sampling method used in this study. Why were 60% of eligible students chosen? I like the idea of sending the students a hard copy letter along with a pen before sending them the email invitation. The authors have not mentioned about ethical approval or exemption for the present study. If the study was done in 2015 them some of the circumstances may have changed and this should be considered while considering the findings.
