Resumen
Objetivo: Comparar el desempeño de estudiantes de medicina en pruebas con consulta compuestas por preguntas abiertas (PCPA), describiendo variables relacionadas con la planificación, la ejecución, el tiempo de examen, el tipo de respuesta y el dominio cognitivo de las preguntas. Métodos: Estudio observacional retrospectivo, basado en la comparación del desempeño de los estudiantes en las PCPA aplicadas sin supervisión (2023.1) y con supervisión y restricción de acceso a las fuentes información (2024.1), en un curso de medicina de una institución privada brasileña. Se consideraron como variables exploratorias: el tiempo disponible para realizar las pruebas, el tipo de respuesta y el dominio cognitivo de las preguntas según la Taxonomía de Bloom. El análisis estadístico se realizó utilizando SPSS 26.0 y Excel 365, adoptándose un nivel de significancia del 5% (p ≤ 0,05). Se utilizó la prueba de Mann-Whitney para comparar los grupos. Resultados: Se analizaron 1.160 PCPA-2023 y 1.146 PCPA-2024. La mayoría de las pruebas supervisadas presentó medias de calificaciones inferiores (p < 0,05), a pesar del mayor tiempo disponible para la prueba y del predominio de dominios cognitivos más bajos. Predominaron las respuestas largas en las PCPA supervisadas. Conclusión: Se observaron diferencias de desempeño entre los contextos evaluativos, lo que indica que las condiciones de aplicación influyen en la interpretación de los resultados y en la confiabilidad del desempeño individual de los estudiantes.
