Personalized System of Instruction (PSI), broadly employed in the 1970's, and Distance Learning (DL) are teaching methodologies that differ from the traditional models of education, in which the critical core of information transmission is the teacher. This work presents the main features of both PSI and DL, highlighting their similarities. Studies in which PSI and DL were used together are described, and the advantages of this junction are discussed. It is suggested, at the end of this work, that using PSI and DL together may be a viable way of dissemination and democratization of quality education, based on empirical evidence of its effectiveness.
