Description

From a preliminary study with four education experts, the authors derived six design requirements (R1-R6) categorized by three analysis objects: the course concept, the student group, and the individual student. The Concept category analyzes attention from the course structure for rapid screening and preliminary attribution; the Group category focuses on temporal attention trends and audiovisual instructional design; and the Individual category centers on "each student's detailed attention trajectory and audiovisual attention allocation." The decomposition matches the experts' agreed top-down workflow from overall course structure to specific causes of attention fluctuations.

Design Implications

Context

Requirements

• Accurate extraction of concepts and their relationships as a prerequisite for helping teachers review the overall course structure

Constraints

• Group aggregated results may mask individual differences, as attention patterns observed at the group level may not hold consistently across individual students

Target Learners

• teachers and course instructors analyzing pilot-cohort attention data

Learning Goals

• locating low-engagement segments and diagnosing audiovisual instructional design deficiencies in instructional videos

Claims

• Two case studies and expert interviews with six experts demonstrated SAVVY's effectiveness and usability for identifying attention variations and supporting video optimization [+M] — the evaluation of the system built to these requirements

Related Designs

• Savvy Visual Analytics System
• SAVVY interactive visual analytics system — the system these requirements were derived for
