Thursday Threads: Technical Debt, QR Codes in National Parks, WebP Image Format, and SSL Cautions

Week #2 of this new project to highlight interesting tidbits from the previous seven days. Well, things that were interesting to me that I hope will be interesting to DLTJ readers. Time will tell.

Experiential Learning Enhanced with 2-D Barcodes

QR-Code pointing to DLTJ

This morning I attended a presentation on “Using QR Codes and Mobile Phones for Learning” at the Ohio Educational Technology Conference. Presented by Thomas McNeal and Mark van’t Hooft from Kent State University, the example used in the presentation was their GeoHistorian Project from the 2009 ISTE conference. By using a pamphlet of 2-D barcodes labeled with strategic locations at the World War II Memorial in Washington, DC, participants using barcode scanners on smartphones were able to call up text and media from various websites while walking around the memorial. They put together a video showing participants walking through the space and their impressions of the 2-D barcode-enhanced experience.

Tom emphasized the need to have an activity that is relevant to the technology. As he put it, “Use the technology to ampliy the activity.” In this specific case, the 2-D barcodes pointed to text, pictures, and videos that provide additional background to the components depicted in the World War II Memorial. As participants mentioned in the video, it is a way add context to the experience of walking through the memorial.
