Computer-Mediated Communication In Higher Education: An Exploration Of Knowledge Construction , Mustafa Tuncay Saritas Jan 2006

Computer-Mediated Communication In Higher Education: An Exploration Of Knowledge Construction , Mustafa Tuncay Saritas

Retrospective Theses and Dissertations

Constructivist theories about knowledge construction emphasize that knowledge construction is more powerful and meaningful when it is actively built up by students through engaging in equilibrated exchanges and experiencing cognitive disequilibrium. From this perspective, knowledge construction is thought to be effective in learning environments where intense interactive discussions can take place, deeply held values are shared, and complex issues examined from multiple perspectives (Harasim, 1990). Computer-mediated communication, more specifically computer conferencing systems (CCS), has captured the interest of educators as an ideal tool to create this type of learning environment, featuring active, participative, and reflective learning;This study developed a ...

A Comparison Of Reading On Computer Screens And Print Media: Measurement Of Attention Patterns Using Eeg , Joel Carl Geske Jan 2005

A Comparison Of Reading On Computer Screens And Print Media: Measurement Of Attention Patterns Using Eeg , Joel Carl Geske

Retrospective Theses and Dissertations

This study explores if media affect attention patterns for subjects reading text. A series of typography studies done in the mid-1990's show that typography for the computer screen does differ from print standards. A further review of the literature suggests that there is a difference in how the brain reacts to various media. Some of these variations indicate a decrease in attention and ability to concentrate. However, no studies have been done to confirm that the task of reading varies significantly dependent on media, nor has the research studied brain patterns of subjects' attention to reading materials using various ...
