 The global pandemic's unprecedented challenges for the education community created new opportunities in distance learning activities and digital education. Whilst there has been a big focus on classroom management tools, there are technologies which have trailed behind, the ones that empower teachers to create comprehensive and engaging learning content. My name is Petar. I am a software engineer and co-founder of the German-based startup Osteles. We initiated our project with the ambition to provide a technology which enables everyone to browse through history in an intuitive and systematic manner and therefore help with the cultural, political and social economic education in our society. We have developed a data model for combining gel spatial, temporal, audio-visual and textual representations of historical information. This provides a basis of a number of applications, one of which we released earlier this year, Osteles-Schule. Osteles-Schule is a digital learning application with a focus on history and social science subjects. Teachers use it to enhance their lessons, create exercises and share interactive resources with their students in a simple yet engaging way. This is one of the public teaching modules where students are asked a variety of different questions on the topic of the Cold War. Observe how the two unions, NATO and the Warsaw Pact, are highlighted with a different color in the context of the current multiple-choice task. Select the country's assignments are an essential part of Osteles-Schule. They allow students to directly interact with the map by marking the correct territories. For other exercise types, such as filling the blanks, the Osteles browser could be used to provide hints in the form of free text, images or links to external resources. Osteles-Schule is built on the Osteles Platform's foundations, which allows it to be extremely flexible in terms of the content. It provides all the tools to create similar presentation and exercise modules to the one you just witnessed. You're enabling teachers to create their own high-quality interactive content quickly and easily. The editor enables users to select images, change the date, map coordinates or zoom level or simply edit the question formulation and add possible answers, either right or wrong. Modules that are created and shared on Osteles-Schule are under the Creative Commons license and can be freely reused and adapted by anyone around the globe. Students access the published modules via web browser anonymously without having to log in in compliance with data privacy standards. The virtual classroom functionality in Osteles-Schule allows teachers to provide their materials in an easy manner. Once a classroom is created for a module, it is assigned a unique link. This link can be then copied and shared across. Osteles complements many of the benefits of digital transformation in the education sector, thanks to which students can access many different materials at score at home through a single device in an easier and inexpensive way by breaking the geographical and cultural boundaries students from around the globe can attend and collaborate in lessons, creating a truly diverse educational experience. We believe that Osteles will help the education sector to become more resilient in the future, especially during crises such as the global pandemic. We believe that its scalability, worldwide availability and high performance will empower educators with the necessary tools for the bright future of history. We'd love to hear from you, so please feel free to reach out to us on social media or via email. Thank you for watching and enjoy the rest of the old conference.
