متن کاملDesigning an online lecture in the discipline of soil science Category: Refereed Professional Practice
Technological developments have not only been introduced to support traditional face to face education, but also to facilitate the spread of distance education programs and online learning. This paper contributes to the development of online lectures based on the foundations provided by learning theories (behaviourism, cognitivism, constructivism and connectivism). Using this approach, the auth...
