Quick response codes as a complement for the teaching of Electronics in laboratory activities

Augmented reality is gaining presence in the classroom because it allows to combine the physical environment and digital information in real time. An implementation of augmented reality that is attracting great attention are quick response codes because they can be read immediately in smartphones and tablets using free apps. A teaching field where it is beneficial to provide a prompt access to supplementary materials are laboratory sessions in scientific-technical disciplines. There, students realize complex measurement tasks using specific instrumentation, and so it is convenient to access technical documentation and explanations of the measurement process during the session. This work describes how quick response codes can be introduced in laboratory sessions to provide links to specifically designed supporting resources. Thanks to this strategy, an improvement in the acquisition of experimental skills has been observed as well as a better and quicker realization of the practical sessions.
