The conversion of the Classroom Challenges from detailed, paper-based lessons to computer-based tablet technologies is well under way.  Development of the activities and software is accomplished through a series of design experiments and usability studies.  We have been holding usability studies beginning in the Fall of 2013 and continuing through 2014.

During usability studies, multi-modal data is captured in the form of multiple video feeds of the overall interaction and close-ups of the individuals, screen-monitoring of the tablets, and log data from the application as well as separate audio recordings.  The image below depicts the screens of two participants in a usability study on Classroom Challenge “Interpreting Distance Time Graphs” as implemented through the FACT system.

Usability Studies have been conducted on large groups of students to replicate the effect of a classroom setting.  The following images were taken from a recent experiment.
