Affective Teacher Tools: Affective Class Report Card and Dashboard.

While using online learning software, students demonstrate many reactions, various levels of engagement, and emotions (e.g. confusion, excitement, frustration). Having such information automatically accessible to teachers (or digital tutors) can aid in understanding how students progress and suggest when and who needs further assistance. We developed the Affective Teacher Tools, a report card and dashboard that present teachers measures of students' engagement and affective states as they use an online tutoring system, MathSpring.org, which supports students as they practice mathematics problem-solving at the middle school level. We conducted two development and research studies - one that assesses teachers perception of the affective report card and a second study that assesses a live affective dashboard, which senses students' affect and performance in a live class that is using MathSpring. We use computer vision techniques to measure students' engagement and affective states from their facial expressions while they use the tutoring system. In this paper, we summarize both the report card and affective dashboard, the research studies and results, and we also discuss implications, and future planned experiments for the next phase of this research.
