Building a theoretical framework of web-based instruction in the context of distance education

This study attempts to analyze teaching and learning processes of web-based instruction (WBI) as shown in recent literature, and to develop a theoretical framework of WBI using a prominent existing distance education theory called Transactional Distance Theory in order to provide better understanding of the essential pedagogical components of WBI. Recent studies have shown that the key elements of the structure of WBI are (1) content expandability, (2) content adaptability, and (3) visual layout. And also three emerging types of interaction, or three aspects of dialogue, in WBI have been identified through the studies. Those types were: (1) academic interaction, (2) collaborative interaction, and (3) interpersonal interaction. Finally, both learner collaboration (or learner collaboravity, if we create a new term) and learner autonomy seem to have emerged in Web-based learning environments.
