Students randomly assigned to a practical workshop group demonstrated higher average quiz score than those students in a discussion or lecture groups. Each symbol represents a subject, bars signify the average (workshop, n = 9; discussion, n = 7; lecture, n = 10) for each experimental condition, and error bars indicate standard deviations. P value significance (*, P < 0.01; NS, not significant) was calculated by ANOVA and adjusted by use of the Bonferroni correction.
