Objective: We sought to evaluate a set of flash cards to teach about lesions of the jaws and maxillary sinuses.
Methods: We placed illustrations of 30 diseases of the jaws and maxillary sinuses on the front of the cards (7 cm × 5 cm). On the backs of the cards, a description of the radiological findings and the corresponding QR code for each disease were printed. Each QR code was linked to a website where actual X-ray images of the lesion could be viewed. Students and radiologists in training could easily access the website by scanning the QR code with a handheld device. The evaluation of the system by students was quite favorable and its utilization rate was high. After a 6-month trial, we conducted a questionnaire. The subjects were 94 fourth-year students at our college, and the questionnaire was anonymous.
Results: The evaluation of the system by students was quite favorable and its utilization rate was high.
Conclusions: The learning content of our learning cards with QR codes was well received by students and was highly useful.
