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.

增强现实在教室中越来越受欢迎，因为它可以将物理环境和数字信息实时地结合在一起。快速响应代码是一种引人注目的增强现实，因为它们可以使用免费应用程序在智能手机和平板电脑中立即读取。在科学技术学科的实验室课程中，提供快速获取补充材料的帮助的教学领域。在那里，学生可以使用特定的仪器来完成复杂的测量任务，因此在会议期间可以方便地访问技术文档和测量过程的说明。这项工作描述了如何在实验室会议中引入快速响应代码，以提供指向专门设计的支持资源的链接。有了这个策略，
