The quantification of open scholarship-a mapping review

This mapping review addresses scientometric indicators that quantify open scholarship. The goal is to determine what open scholarship metrics are currently being applied and which are discussed (e.g., in policy papers). The paper contributes to a better understanding of how open scholarship is quantitatively recorded in research assessment and where gaps can be identified. The review is based on a search in four databases, each with 22 queries. Out of 3,385 hits, we coded 248 documents chosen according to the research questions. The review discusses the open scholarship metrics of the documents as well as the topics addressed in the publications, the disciplines the publications come from, and the journals in which they were published. The results indicate that research and teaching practices are unequally represented regarding open scholarship metrics. Open research material is a central and exhausted topic in publications. Open teaching practices, on the other hand, play a role in the discussion and strategy papers of the review, but open teaching material is not recorded using concrete scientometric indicators. Here, we see a research gap and discuss the potential for further research and investigation.
