Abstract

An instructional technology application of QR (quick response) codes for introducing commonly used chemistry laboratory apparatus for visually impaired students will be presented. Audio commentaries describing commonly used laboratory apparatus were recorded. The commentaries consisted of concise introductions and applications of a variety of apparatus used in high school and undergraduate chemistry laboratories. The QR code for each apparatus was produced and linked to the corresponding audio commentary via a unique URL. The QR code labels were attached to the apparatus. Students scanned the QR codes on their mobile device and followed the audio commentaries for a hands-on learning experience. Chemistry learning modules based on audible chemical reactions will be presented. A titration experiment based on audible detection of the end point will be presented. Quantitative data on the students’ response to the post-activity survey questions underscored the efficacy of the chemistry learning modules.
