Resumen
Effective applications of IT in education are those aligned with the teaching/learning model driving the course and the spatial and temporal boundaries of the communication. Pedagogical models can be broadly classified into objectivist, which emphasizes the one-way transmission of concepts from professor to students, and constructivist which is based on the belief that knowledge emerges from interaction. IT applications consistent with the objectivist model are aimed at mediating the lecturing process by complementing or replacing the traditional role of professors and printed materials. IT applications in the constructivist paradigm consist of supporting collaborative learning environments during lectures and beyond them. The temporal dimension of communication refers to whether a course is taught in real time or delayed time. The conceptual model presented in the article integrates the three relevant dimensions, pedagogy, location, and mode, to illustrate the alignment between different alternatives.
