Comparison of overall student performance on final multiple-choice exam
TD
Next we compared students’ exam scores before and after the educational intervention for all students in the TD (n = 129) and OFC groups (n = 114) and students in the TD (n = 23) and OFC groups (n = 28) who responded to the survey. Students answered 20 ophthalmology multiple-choice questions (MCQ) as part of completing the course. Each question had the same weight, and the total score was converted into a 0–100 scale. Independent samples t test was used to compare the differences between the two groups. This analysis of the final exam MCQ score showed that there were no statistical differences between the TD and OFC group (P = 0.0651). Comparison of the final exam MCQ score for survey responders between the TD and OFC found no evidence of a statistical difference in the score achieved. Overall, this indicates that the OFC did not negatively influence knowledge gain.
