Abstract
Introducción: La Bioquímica Médica es una asignatura fundamental en la formación de los estudiantes de medicina, aunque frecuentemente se percibe como abstracta y de difícil comprensión. Esta situación repercute en el bajo rendimiento académico y la escasa conexión con la práctica clínica. Objetivo: Evaluar el impacto de una estrategia didáctica basada en casos clínicos y prácticas experimentales sobre el rendimiento académico de estudiantes de segundo semestre en la asignatura de Bioquímica Médica. Métodos: Estudio cuasi-experimental con 137 estudiantes distribuidos en cuatro paralelos. Se aplicó una intervención pedagógica integrando análisis de casos clínicos con prácticas de laboratorio. Se evaluó el aprendizaje mediante pretest teórico, postest clínico integrador y calificaciones prácticas. Se emplearon pruebas t de Student, ANOVA y correlación de Pearson. Resultados: El rendimiento académico mejoró significativamente tras la intervención (M pretest = 4,57; M postest = 8,43; p < 0,001), con un tamaño del efecto grande (d = 1,13). El análisis ANOVA reveló diferencias significativas entre paralelos (p < 0,001). Se observó una correlación positiva moderada entre el postest y el promedio general teórico-práctico (r = 0,640; p < 0,001). Conclusiones: La implementación de casos clínicos y prácticas experimentales tuvo un impacto positivo en el rendimiento académico, favoreciendo el aprendizaje significativo y la integración entre teoría bioquímica y razonamiento clínico. Se recomienda su aplicación sistemática en el currículo de ciencias básicas médicas.
Medical Biochemistry is a fundamental subject in the training of medical students, although it is often perceived as abstract and difficult to understand. This situation impacts on poor academic performance and the poor connection with clinical practice. Objective: To evaluate the impact of a teaching strategy based on clinical cases and experimental practices on the academic performance of second-semester students in the subject of Medical Biochemistry. Methods: A quasi-experimental study with 137 students distributed in four parallel classes. A pedagogical intervention was applied integrating clinical case analysis with laboratory practices. Learning was assessed using a theoretical pretest, an integrative clinical posttest, and practical grading. Student t-tests, ANOVA, and Pearson correlation were used. Results: Academic performance improved significantly after the intervention (M pretest = 4.57; M posttest = 8.43; p < 0.001), with a large effect size (d = 1.13). The ANOVA analysis revealed significant differences between parallel subjects (p < 0.001). A moderate positive correlation was observed between the posttest and the overall theoretical-practical average (r = 0.640; p < 0.001). Conclusions: The implementation of clinical cases and experimental practices had a positive impact on academic performance, promoting meaningful learning and the integration of biochemical theory and clinical reasoning. Their systematic application in the basic medical sciences curriculum is recommended.
