Resumen El valor del material escrito de autoaprendizaje (MEDA) en la educacion a distancia radica en su calidad pedagogica, necesaria para lograr un aprendizaje significativo. Objetivo. Disenar un modelo para evaluar la calidad pedagogica de los MEDAs, y un instrumento confiable y valido. Metodologia. El estudio se realizo en la Universidad Industrial de Santander (Bucaramanga, Colombia). Inicialmente se diseno el modelo para la evaluacion de MEDAs. Luego, se procedio a elaborar el instrumento: se definio el concepto de calidad pedagogica de un MEDA; se analizo la validez de contenido (analisis factorial) y la confiabilidad del instrumento (coeficiente alfa de Cronbach). Resultados: se obtuvo un modelo de evaluacion agil y un instrumento conformado por 28 items, constituidos en un solo factor, coeficiente alfa de Cronbach de 0.96 y un poder para reconocer las diferencias entre los elementos pedagogicos de un MEDA construido desde el Inductismo y otro desde el constructivismo. Palabras clave: Evaluacion de modulos, evaluacion de materiales escritos, construccion de instrumentos de evaluacion. Evaluation ofwritten material of self-learning for education at distance SUMMARY The value of self-learning written material on Distance Education is based on its pedagogic, quality necessary to achieve a meaningful learning. Objective. To design both a model and a reliable valid instrument to evaluate the pedagogic quality of the self-learning written materials. Methodology. The search was carried out at Universidad Industrial de Santander (Bucaramanga, Colombia). Firstly, a model was designed for evaluating the materials mentioned above. Thereafter, the instrument was elaborated and it was defined the concept of pedagogical quality of the self-learning written materials. They were also analyzed the validity of content (Factorial analysis), and the confidentiality of the alpha coefficient of Cronbrach instrument). Results. It was obtained an agile evaluation model and an instrument composed by 28 items, all constituted into one only factor; alpha coefficient of Cronbrach of 0.96 and a power to recognize the differences between the pedagogic elements of a self-learning written constituted from the inductive approach and another from the constructivism approach. Key words: Evaluation of modules, evaluation of materials writings, construction of evaluation instruments.
