This Fast Company video shows how Rebecca Minkoff (designer of luxury handbags, accessories, footwear and apparel) uses technology at a prototype of one of her specialty retail stores. The video offers an example to show when you cover the future of retailing in class.
To foster active learning, you might ask students why retailers are investing in new technologies like these. You could also ask students to imagine other technology applications for retail stores. I find it helpful to have them work in pairs or small groups on these questions for 3-5 minutes before soliciting ideas from individuals. I often have them write out their ideas and hand them in for “credit” and to encourage staying on task.
