Abstract:
QR codes are two-dimensional barcodes whose black modules on a white background carry various information (text, images, links on websites, or videos). Their application is broad-spectrum: product tracking in production, logistics, healthcare, marketing, and many others. It is possible to apply them wherever we want to provide the user with certain information, and conditions allow the application of a QR code in a given environment. However, this paper describes the implementation of QR codes in the educational process. Specifically, it is the use of QR codes for the subject Measurement of technical quantities, the content of which is the interpretation of theoretical background and the implementation of experimental measurements carried out by students in laboratories. Measurements require adherence to the methodological procedure and full-fledged information to have a reliable, informative value and detect or eliminate possible measurement errors. As part of the measurements, students work with various devices and aids whose operating parameters are unreadable by frequent use. If this information were processed into a QR code, and the student had a mobile phone with a camera and software to decode this type of code, the data would be available immediately, with the required informative value, and available for download. Students must interpret the measurement results in the form of an electronic file - Measurement Protocol. By elaborating protocols, they acquire theoretical background from the given measurement issue, define measurement conditions, state the values of measured quantities, and subsequently interpret the measurement results in graphical form. If the QR code of the given protocol was available in scripts or at the measuring stand itself, the students would be allowed to download this template and write the information and data directly during the measurement into this electronic protocol without the need to rewrite the data from other display units on paper.
