Satisfaction of medical students in studying histology using virtual and light microscopy: A cross-sectional study

ABSTRACT

Background@#Medical education has changed as a result of the COVID-19 pandemic. There has been a shift from face to face learning to virtual classes using online learning platforms such as Canvas. These virtual and online alternative methods to medical education brought up concerns about the preparedness of medical students in studying Histology. This study addresses the student’s preference and attitude on the learning of histology using light microscopy vs virtual microscopy. @*Objectives@#The specific objectives of the study are to determine students’ preference, attitudes, and overall satisfaction on the use of light microscopy vs virtual microscopy using a Likert scale. @*Methods@#An enhancement program was conducted by the Department of Anatomy, UP College of Medicine from June 13 to June 17, 2022 among first year medical students. The students were exposed to prosected cadavers, models, specimens, histologic glass slides, and electronic images. During the activity, the second and third floor of Calderon Hall was divided into several stations, each with its own learning outcomes.This is a descriptive cross-sectional study. In all the learning stations, both virtual and light microscopy learning modalities were made available to the students. The student was at liberty to select virtual microscopy, light microscopy or both. In one of the stations, allocated to OS 205 (The study of the anatomy and histology of the thorax), students were randomized to one learning modality (light vs virtual microscopy) and made to identify one predetermined structure. Students answered a short questionnaire that allowed them to express their preference for the modality that was assigned. The questionnaire survey included questions on students’ preference for either light microscopy (LM) or virtual microscopy (VM), ease of use, and satisfaction. A total of five statements were included in the survey questionnaire. All questions in the survey were scored on a 5-point Likert scale (5 strongly disagree, 4 disagree, 3 neutral, 2 agree, and 1 strongly agree). A comments section was also included in the survey to explore students’ experiences of the two learning methods.@*Results@#A total of 160 students participated in the study. Seventy-nine (79) students were randomized to the light microscopy group and 81 one students were randomized to the virtual microscopy group. There were no differences in the demographic characteristics between those randomized to virtual vs light microscopy.There were no differences in the net ratings between those randomised to virtual vs light microscopy in the following domains 1) ease in looking for structures, 2) ability to identify the structure correctly, 3) method enhancing learning, and 4) overall satisfaction. There was a difference in the net rating between those randomized to virtual vs light microscopy in the domain on quality of the image being easily adjusted (58% vs 97.5%).@*Conclusion@#Medical students who used light microscopes demonstrated a more positive attitude towards its ability to enhance learning and showed greater satisfaction in using this method. Ease in manipulating image quality was better in the light microscopy group. However, the accuracy of identification of histological structures using either platform did not differ. Both virtual and light microscopy are effective learning methods.
