Designing for Engagement: Evaluating Perception of Quick-Response (QR) Codes in Informal Environmental Education and Outreach Materials

Incorporating Quick Response (QR) codes in informal environmental education signage is widespread, but existing studies primarily focus on marketing rather than engagement in environmental issues. We present two case studies that provide new insights into the potential usefulness of QR codes as a mediating tool in informal environmental education and outreach. Overall, few participants attempted to read QR codes, but 73% of survey-takers had positive perceptions, decreasing with age. Education level did not impact perceptions. We surmise that interest in linked information influenced QR code use the most and suggest best practices for their incorporation into informal learning materials.
