Quantitative and Qualitative Literature Review of Augmented Reality in Teaching

At Paderborn University, an AR-based app is being developed to prepare electrical engineering students for laboratory work. This paper aims to review the development of AR since 2010, particularly in technical university laboratories, through a systematic literature review. The study investigates AR's relevance in university teaching and examines specific AR applications in laboratory settings. Using a mixed-method approach, the research first employs a web crawler to gather 27,249 articles from the Lens database, followed by a bibliometric analysis. Further, Google Scholar is used to find 374 articles related to AR in scientific and technical laboratories, with 51 significant ones evaluated for application areas, findings, and other criteria. The findings show that AR in education is a growing trend, with a significant increase in publications and citations in recent years. Most studies focus on marker-based mobile AR applications, assessing aspects like motivation and user experience through surveys and interviews. However, there's limited research on AR's learning effectiveness in laboratories, partly due to the scarcity of technical equipment. One study found no significant learning impact from AR.
