Irrespective of how digitally savvy they think they are, most people will spend the majority of their time browsing online content before walking away without leaving a social trace. On other occasions, however, they go online purposely to meet people and interact. The first is visitor behaviour, the second is resident behaviour. This idea of visitors and residents defines opposite ends of what is really a smooth continuum, with private, functional use of the web at one end and highly visible activity at the other.
Joyce Kincannon on 01 Apr 15"Despite our best efforts, presentations can sometimes turn into one-way communication- us talking and students passively listening. You may be stationed at the front of the classroom, perhaps using PowerPoint slides or showing a video on a screen, while the class follows along silently in their seats. Or, any discussion that is generated might be dominated by the verbal few, with quieter students too intimidated to jump in. Also, when you look at the multiple studies that indicate the brevity of a student's attention span, ranging from two to ten minutes, a lengthy presentation can lose the audience it was designed to teach."
