Aim To evaluate the impact of an educational intervention focused on teaching students to create infographics to improve pharmacology learning. Design This is a comparative study. Methods The population was 250 nursing students who had to create two infographics in groups related to the content that had been addressed in pharmacology in two different moments. Students and professors evaluated the infographics through a 5‐point Likert scale. Scores from the official exam of the pharmacology subject were obtained. Results Most of the students scored below 50% for the “excellent” and “good” categories. Intraclass correlation and kappa correlations among students and professors' evaluations were low. The comparison between both times of students' evaluations only yields significant correlation values for the criterion “Understanding of information” ( r = .039, p = .024) and the “Visual presentation of information” ( r = .041, p = .019). No correlation was obtained between the test and evaluations values of the infographic.
