Abstract
Objective

To analyse a problem-based learning experience (PBL) in the sixth year of medicine, within a course organised in successive rotations of 12 school days for 7 annual groups.

Material and methods

Each group was divided into subgroups of 6–8 students. Each subgroup was assigned two cases with radiographic images that they had to prepare and present in a joint session in which the students discussed each case and the teacher acted as moderator, without providing solutions. Finally, they had 15 days to complete the debate in an online forum and prepare a written report on each case.

Results

During 6 consecutive years, 1001 students participated, whose annual grades ranged between 7.7 ± 1.6 and 9.0 ± 0.7 (mean ± standard deviation). No correlation was found between the degree of difficulty assigned to the cases and the mean score obtained by each group (R2 = 0.0115). Sixty-six point two percent completed a questionnaire rating various aspects of this experience above 4 out of 5 points and providing overall scores above 8.3 out of 10 points in the different years. The students found this experience appropriate to the objectives of the subject and useful for their educational needs.

Conclusions

PBL allows students to acquire skills of understanding, reasoning and deepening in radiological diagnosis. This study demonstrates that an experience based on PBL can be included in a radiology course organised in a traditional way, allowing students to be graded regardless of the difficulty of the cases.

Resumen
Objetivo

Analizar una experiencia de aprendizaje basado en problemas (ABP) en sexto curso de medicina, dentro de un curso organizado en rotatorios sucesivos de 12 días lectivos para 7 grupos anuales.

Material y métodos

Cada grupo se dividió en subgrupos de 6–8 estudiantes. A cada subgrupo se le asignaban dos casos con imágenes radiográficas que debían preparar y presentar en una sesión conjunta en la que los alumnos debatían cada caso y el profesor actuaba como moderador, sin aportar las soluciones. Finalmente, disponían de 15 días para completar el debate en un foro online y elaborar un informe escrito de cada caso.

Resultados

Durante 6 años consecutivos participaron 1001 alumnos, cuyas calificaciones anuales oscilaron entre 7,7 ± 1,6 y 9,0 ± 0,7 (media ± desviación estándar). No se encontró correlación ente el grado de dificultad asignado a los casos y la calificación media obtenida por cada grupo (R2 = 0,0115). El 66,2% completó un cuestionario valorando diversos aspectos de esta experiencia por encima de 4 sobre 5 puntos y aportando puntuaciones globales superiores a 8,3 sobre 10 puntos en los diferentes años. Los alumnos encontraron esta experiencia adecuada a los objetivos de la asignatura y útil para sus necesidades educativas.

Conclusiones

El ABP permite a los estudiantes adquirir competencias de comprensión, razonamiento y profundización en el diagnóstico radiológico. Este estudio demuestra que se puede incluir una experiencia basada en ABP en una asignatura de radiología organizada de forma tradicional, permitiendo calificar los alumnos con independencia de la dificultad de los casos.
