Relevant Information and Information Visualization for Lecturers in Web‐Based Audience Response Systems
0 likes1,818 views
The document discusses improving an existing audience response system (ARS) called RealFeedback for lecturers. It analyzes RealFeedback's strengths and weaknesses by comparing it to other systems and interviewing lecturers. Key findings are that lecturers want to be able to view sessions from previous classes, mark answers as correct, see visualizations of the number of votes and voting speed. The document proposes visualizing this information through additions to RealFeedback's hierarchy and interface.
