RESUMEN
El sistema educativo cubano actual necesita que los docentes de la educación médica superior puedan usar de manera correcta y eficaz la totalidad de los medios de enseñanza que estén a su alcance. Este trabajo tiene el propósito de argumentar la importancia de la utilización del pizarrón en aras de aumentar la calidad en el proceso de enseñanza aprendizaje potenciando la función educativa y humana del maestro. Ninguno de los adelantos de la ciencia y la técnica que existen en las aulas hoy debe sustituir al pizarrón como base para una buena exposición del material a aprender y para generar experiencias de aprendizajes, por lo que se exponen algunas consideraciones sobre su efectividad como medio de percepción directa y modelo explícito de comunicación.
The Cuban educative system needs that the higher education professors can use in a proper way all the teaching aids at their disposal. The purpose of this work is to back up the importance of the use of the chalkboard so as to increase the quality of the teaching-learning process favoring the educative and humanistic functions of professors. None of the scientific advances that are in the classrooms at present should substitute the chalkboard to teach the contents and to generate learning experiences, that´s why some considerations are exposed about its effectiveness as a teaching aid of direct perception and a model of explicit communication.
