The aim of this article is to empirically investigate the advantages and disadvantages of different search strategies in synthesizing research papers that use Virtual Reality (VR) educational technology. The aim is to identify cognitive biases on the part of the reviewers through different concrete searches. Using two search strategies, the study identifies the extremes between an AND search that finds as few irrelevant studies as possible but overlooks relevant ones, and an OR search that searches as broadly as possible but picks up many irrelevant studies. The article aims to show how systematic searches in educational research should be designed to adequately address the typical challenges of systematic analyses (e.g., recall-precision problem, cognitive load).

The search strategies were developed based on a Google Scholar search for existing systematic reviews on VR. Here, the two search strategies differed only in terms of their linkage between a technological (VR) and a pedagogical search term. The two elements were linked with either an AND or an OR. The search items were screened in a two-person cross design and evaluated on different measures of precision and recall.

There was no evidence that the more comprehensive search (OR) is superior to the narrower search (AND), but slight evidence of cognitive biases in the screening or search process in the more comprehensive search (OR). These results should be further evaluated, investigated, and, above all, replicated in further studies.

Open educational resource (OER) as free teaching and learning materials can contribute to the collaborative design and development of teaching. To support higher education teachers in their work with teaching in general and OER in particular and to encourage their use of OER, it is necessary to pay attention to their needs and requirements. This paper presents the results of a research project, identifying the usage behaviour of German-speaking higher education teachers. In an interview study, they were asked about their experience with OER to get detailed insights into their practices concerning their \‘use\’ and \‘revise\’ of materials. From this, four user types were derived according to different OER activities, such as creating, reusing, editing, and publishing OER, and their scope. Finally, these user types are transferred to considerations when designing OER infrastructures and establishing support options. These are aligned with the specifics of each user type, making the research findings a complementary contribution for application in higher education.

Open Educational Resources (OER) erm\öglichen, digitale Lehr- und Lernmaterialien frei verf\ügbar und ohne Einschr\änkungen nutzbar zu machen. Daher haben OER grosses Potenzial, Lehre kollaborativ zu gestalten und zu entwickeln. Um die Nutzung von OER zu f\ördern und Hochschulehrende im Umgang mit OER unterst\ützen, ist es wichtig, auf deren Bed\ürfnisse und Anforderungen einzugehen. Daf\ür sind detaillierte Einblicke in Praktiken und Verhalten der Lehrenden bei der Verwendung und \Überarbeitung von Materialien notwendig. In diesem Beitrag werden Ergebnisse eines Forschungsprojekts vorgestellt, welches Nutzungsverhalten von OER durch Hochschullehrende identifiziert. Methodisch wurde eine Interviewstudie mit Hochschullehrenden \über ihre praktischen Erfahrungen bei der Arbeit mit OER durchgef\ührt. Auf dieser Basis wurden Anwendungstypen abgelei-tet, die sich auf die OER-Aktivit\äten bei der Erstellung, Nutzung, Bearbeitung und Ver\öffentlichung von Materialien beziehen. Hieraus konnten Optionen bei der Gestaltung von OER-Infrastrukturen und Unterst\ützungsm\öglichkeiten f\ür deren Nutzung ermittelt werden.

When designing OER infrastructures it is essential to be aware of practices higher education teachers have for digital environments while reusing and revising as well as sharing OER. Therefore, we conducted an interview study and designed a prototype concept based on expectations and requirements of higher education teachers regarding version management and collaborative elements.

Open Educational Resources (OER) bilden ein wichtiges Element im Diskurs \über eine
Digitalisierung von Bildung. Der Beitrag erhebt den Stand der internationalen empirischen Forschung zu OER, um dadurch Desiderate f\ür eine zuk\ünftige Forschungsagenda aufzuzeigen. Mittels eines systematischen Mapping-Ansatzes wird daf\ür die empirische, englischsprachige Forschungslandschaft kartiert. Die Ergebnisse zeigen, dass Forschung vor allem im Hochschulbereich betrieben wird und wenige Studien f\ür den Bereich Schule vorliegen. Forschungsmethodisch sind quantitative Studien pr\ävalent, die vorwiegend umfragebasiert durchgef\ührt werden. Das prim\äre Forschungsinteresse der Studien konzentriert sich auf Wahrnehmungsfaktoren von OER sowie auf deren \Übernahme und Nutzung in der Bildungspraxis. Ein weiteres Forschungsfeld sind Offene Textb\ücher und deren komparative Kostenvorteile oder qualitative Vergleichbarkeit mit kostenpflichtigem Bildungsmaterial. Forschungsdesiderate liegen im Feld der Usability respektive Benutzerfreundlichkeit von OER-Repositorien. Forschung hierzu k\önnte die zahlreichen Bundesl\änderinitiativen zur Etablierung von OER Landesportalen unterst\ützen. Weitere Forschungsl\ücken finden sich bei den Effekten der Nutzung von OER auf das p\ädagogische Handeln und die Ver\änderungen etablierter Bildungspraktiken.

For almost 20 years, Open Educational Resources (OER) are an integral part of the debate about the digitisation of education. However, the empirical landscape of OER research is vivid and largely obscure.
This article reviews the state of international empirical research on OER to reveal trends and gaps and, in this manner, identify possible desiderata for further research. We use a systematic mapping approach to examine the empirical English-speaking research landscape from 2015 to 2019. The results reveal that research primarily concentrates on the higher education sector, while only a few studies are available for the school and other educational sectors. In terms of research methodologies, quantitative approaches
are prevalent, with most of them being survey-based. The main research interests of the empirical studies lie in the perception of OER and the barriers to their use in educational practices. Open textbooks as a form of OER and their comparative cost advantages or qualitative comparability with traditional
educational material constitute an emerging research field that is almost exclusively located in the U.S.
Research gaps exist regarding the usability and user-friendliness of OER repositories. Addressing these gaps could support the numerous initiatives in different countries to establish and equip repositories.
Additional gaps for empirical research were identified regarding the effects of the use of OER on pedagogical approaches and established educational practices.

Open informational ecosystems play a crucial role in fostering open educational resources (OER) and allow new opportunities to share and collaborate in the learning and teaching environment. Such ecosystems containing interoperable infrastructures and open interfaces aim at fulfilling user needs and fostering practices related to the concept of OER and the five user rights (5 R\&$\#$39;s). To fully embrace this role, those ecosystems need to be designed carefully. In this paper, we discuss implications for open informational ecosystems to fully comprise the concept of OER and related user needs. We carried out literature reviews to analyse recent aspects of the 5 R\&$\#$39;s in relation to user behaviour and infrastructures. We will introduce the results from these reviews and illustrate upcoming questions and challenges for the design of an ecosystem respecting the 5 R\&$\#$39;s conceptual ideas. With our recommendations, we aim at contributing to a better understanding of the concept of OER to improve ecosystem development and implement useful and user-friendly functions.
