	abstract = {<p>Das Internet bricht etablierte Praktiken der Unterrichtsvorbereitung auf. Neue Akteure werden sichtbar und die Rolle der staatlichen Regulation wird infrage gestellt. Wie finden Lehrpersonen an Schulen Unterrichtsmaterialien und wie gehen sie mit selbst entwickelten Materialien um? Eine large-scale Untersuchung mit 1.960 Lehrpersonen aus Deutschland erfasst ihre Handlungspraktiken mit Blick auf die Informationsquellen und Formate der Kollaboration. Die Ergebnisse best\&auml;tigen vorliegende Befunde, wonach Lehrende Materialien aller Art in den Weiten des Internets \&ndash; vor allem \&uuml;ber \&laquo;Google\&raquo; \&ndash; suchen. Sie sammeln, entwickeln diese f\&uuml;r sich und tauschen sich kaum mit Kolleg:innen aus. F\&uuml;r die weitere Entwicklung eines informationellen \&Ouml;kosystems f\&uuml;r Bildung, das schul\&uuml;bergreifend einen Rahmen f\&uuml;r Lehren und Lernen in Schulen schafft, gilt es, das Zusammenspiel der Akteure neu auszurichten. Neben der Bereitstellung von offenen Materialien durch private und staatliche Anbieter:innen kommt insbesondere der kollaborativen Erarbeitung und (Nach-)Nutzung eine besondere Bedeutung zu.</p>

	title = {Open Educational Resources in K-12: Common Predictors for Creating and Reusing Fall Short},
	journal = {Open Praxis},

	year = {2024},
	chapter = {347{\textendash}361},
	abstract = {<p>Despite widespread efforts to promote Open Educational Resources (OER) in German K-12 education, their adoption remains relatively low. Previous research has identified common enablers and barriers to OER adoption (i.e., OER (re)use, adaptation, and creation) from an international and intercultural perspective while a hierarchy of such predictors has not been established yet. In order to inform future support structures and policies, this study aimed to identify the most important enablers and barriers to OER adoption in German K-12 education. For this purpose, common enablers and barriers as well as survey items covering these were identified through a literature review. 1,639 teachers were surveyed. While the tested models for whether and how often educators reuse or create OER showed significance, their predictive power was limited. Notably, awareness of OER, and the frequency of cooperation and local sharing of educational resources were the strongest and most consistent predictors. Other predictors such as lack of high-quality material, lack of time, attitude towards sharing, and OER-related skills were less consistent or showed little explanatory power. In conclusion, commonly identified enablers and barriers alone cannot fully explain OER adoption patterns in this context. These findings highlight the need for more context-specific approaches to enhance OER integration which in turn could inspire OER promotion in similar contexts.</p>

not only are metadata standards necessary, but also open Application Programming Interfaces (APIs) are required in order to exchange information. In conclusion, it is essential that all relevant stakeholders agree on an explicit policy to be developed collaboratively. A metadata exchange service can serve to connect all partners.},

The article presents two cases of reference plattforms (Elixier and Edutags) using different ways to aggregate the contents. A comparison of the inventories of both systems makes visible that each system can benefit from the other{\textquoteright}s metadata. For the example of OER (open educational ressources) it can be shown how automatic aggretation can support manual tagging. As a conclusion a joint system is suggested that combines different aspects of both platforms.},
