Data collection
Before conducting the study, students received explanations regarding the courses, surveys and tests that they would participate in and provided confirmation of their agreement to the data collection and processing methods. Data collection included the self-assessments taken before and after the epidemiological course and the follow-up test scores. Basic information, including age, sex, university, major and prior experience in the study of epidemiology, was also collected through the survey. All data were collected on-site.
